The KE0VH Hamshack Sept/Oct/Nov 2020

January 11, 2021

Well, dadgummit (no he didn’t dad had teeth!) here I am finally getting around to getting out a 3 month edition of “the Hamshack”.  Lots of stuff to share with you in this edition, so buckle up it may be a long one.  But a lot has happened since August, so let’s get started.

By the way, I have a small editorial that I am writing here that will be at the end of this month’s article.  Just a heads up.  It’s a doozy…………….

The new repeater is up and operating at the weekend and getaway QTH of Cris W5WCA in the Grand Lake area north of Granby.  448.250 covers a large portion of the valley and Cris reports that you can get into the repeater going down the east side of Berthoud pass and on thru the towns of Winter Park, Frazer, and the rest of the valley.  We were worried about Cris’ place there during the “Troublesome” fire that destroyed many homes in the area around Grand Lake but thank the Good Lord Cris’ and Amanda WØHOP’s places were spared, where so many others lost homes.  We are thankful primarily for that of course, and that the repeater is still on the air for that area connected to SkyHubLink.  The repeater is a Motorola pair with a flatpack duplexer and is putting out 20 watts on AllStar node 506061 connected to SkyHubLink fulltime!

The repeater at W5WCA’s cabin, Coverage map, and the Cushcraft AR-450 antenna.

And now after a wait the long anticipated 449.625 has finally found its permanent home on the marvelous site of Mt. Morrison between the towns of Golden and Morrison on the west side of Lakewood overlooking the Denver Metro.  This site has just a TREMENDOUS view of the metro area and the repeater is covering from Castle Rock up to Greeley and some of the mountain valleys west.  We seem to have a shadow though up I-25 thru Thornton and north.  The antenna is a Diamond X-50 and the repeater is Fusion digital with full Wires-X capabilities.  You can steer the repeater around the Wires-X system with your Yaesu Fusion radio in Wires-X mode.  On Saturday nights we put 449.625 on the America Link Wires-X room for the International Wires-X net.  Check it out sometime and have fun with the repeater!  And thanks to the crew who helped set up the repeater on that beautiful day.  KD0SIY, N0XRX, W0SKY, KD4DT, KE0LNU, & KE0VH, with a special thanks to the site manager Mark Smith for helping us out!

As of this writing as well we are anticipating getting a new Fusion Wires-X repeater on the air from Milner Mountain above Loveland in the next month thanks to Conrad KØSVT.  This system will give great fill in Fusion Wires-X coverage from Thornton north to the Wyoming line and all of Ft. Collins, Loveland and Longmont.We also have been given another analog system that we will think about where it is needed in 2021.  Plus the 449.575 repeater will be on air soon covering a large area near Pueblo for SkyHubLink from Bakulite Mesa on the NW side of Pueblo.  Stay tuned for details on when these machines come on line.

The new home on Milner Mountain for the new 447.800 Fusion Wires-X repeater (not shown) and the old derelict and abandoned Motorola repeater that will find a home sometime on SkyHubLink.

😊So how about “Shopping Cart Mobile”!  Gotta always have your radio with you!  One day at King Soopers! 😊

Another project at “The Hamshack”.  I was wanting to use my Astatic D-104 microphone with the Yaesu FT-991A, so sure enough someone had information on how to do the modification already, so I ordered the little kit from W2ENY on Ebay.  (https://www.ebay.com/itm/W2ENY-HiFi-kit-replacement-element-for-Astatic-D-104-All-Models/233277861976?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20160323102634%26meid%3Dd181a0ac62574f338a5f6efefb27fc7f%26pid%3D100623%26rk%3D4%26rkt%3D5%26mehot%3Dpp%26sd%3D352922839514%26itm%3D233277861976%26pmt%3D0%26noa%3D1%26pg%3D2047675%26algv%3DDefaultOrganic&_trksid=p2047675.c100623.m-1 ) It works great.  The kit comes with everything you need to do an upgrade for todays transceivers including a voltage blocking cap.  And, the microphone is easily reverted back to its original form if you so desire at a later time.  So these days you will hear me on the mic when I am at home on the FT-991A it will be on the modified D-104!

 

The old original dynamic mic element removed from the head of the D-104, and the new condenser assembly

 

 

And old Amazon mailer as the backer/insert padding to hold the element in place, and the finished conversion wired into the FT-991A.  I left the original 4 pin Kenwood type plug assembly on the mic cable, and adapted to the RJ-45 type input on the radio with a temporary setup to test.  My favorite microphone of all time, will never part with it.  Well, at least not while I am alive!  😊😊😊

Another project fix from Skyler WØSKY.  So the repeater for WØJRL analog 447.175 on SkyHubLink, an older Yaesu DR-1, lost its transmit.  We had been operating the repeater on Lookout Mountain (and may be moving it soon to a better location) and all of a sudden it stopped transmitting.  Well Skyler went up and found that the transmit section was indeed dead.  So with a little research and his ingenuity, he managed to insert a Motorola VRM-650 and get it to interface to the DR-1 controller. The repeater is based on a pair of FTM-400’s contained in the repeater box.  Skyler found the pinouts for both radios and matched them up.  Now we are running this repeater as analog, but Skyler is confident that it COULD possibly be used as a YSF digital repeater. The VRM-600 is capable of passing digital signals and can be used for DMR and possibly P-25 digital modes too.  The Motorola however is only capable of 20 watts full duty cycle, so it wouldn’t be quite as powerful as the original FTM-400 50 watt radio.  Skyler refers to it as the “YaesuRola” or “FrankenFusion” repeater.  We will be redeploying it soon at a better location for analog coverage to complement 449.450.

On the left you can see the Yaesu radio and on the right is the Motorola VRM-600

***********************************************************************************************************************

AND another NET joins the SkyHubLink system!  If you have digital questions and would like to learn more about operating those modes such as DMR, FUSION WIRES-X, and others, be sure to join Doug KEØDC and Bucky (Bill) WØSUN on the radio or Google Meet where they will talk about everything digital radio, It’s held on Wednesdays at 19:00 (7pm) MST on the Sky Hub Link. You do not have to have a digital radio to participate, you can join them via analog 449.450 and the various AllStar connections. For more information and how to connect, go to https://skyhublink.com/repeaters/ and https://skyhublink.com/nets/.

****************************************************************************************

HEY!  A GREAT FIND on Amazon for a power supply that will power just about any radio!  It says it is rated at 30 amps.  When I was running it in the shack I didn’t notice any voltage fluctuations or noise being generated either.  It seems pretty darn solid in testing.  We are going to use it to power a node radio for the Pueblo 449.575 repeater connection back to the SkyHunLink system.  So far as we have not been able to deploy the system yet, during Skyler W0SKY’s testing the power supply bears itself out!  And, it is very small, at 7.75 x 3.25 x 1.5 inches.  Now I haven’t tried to power my FT-991A with it, but it supposedly has enough horsepower 😊 to do so.  The voltage output is adjustable with a small pot next to the output section.  So far, I am suitably impressed!

A closeup of the output side of the power supply showing the voltage adjustment pot.

The Motorola GM-300 analog node radio, the Raspberry Pi3 AllStar link with fan (Love the lights!) and the Power Supply with a volt/amp digital meter.  This is the AllStar node radio that will be deployed for the Pueblo 449.575 repeater.  The node setup will be hosted by our good friend Ray, AAØL.

As mentioned above, you can adjust the voltage out of the supply with a pot located just to the left of the outputs for a “perfect” 13.8 volts!  And it just plain looks GREAT!  Easily readable!

The Pueblo repeater on 449.575.  This had been deployed on Mt. Princeton working well for a couple of months until the 449.925 Methodist mountain repeater came on line.  Now it has been re-allocated for the Pueblo area from Bakulite Mesa.  We hope to deploy this one weather and scheduling permitting before the end of the year.

Tom KD4DT is the proud owner of a new Yaesu FTM-300 and shows the way that he mounted the control head in the dash of his car.  The radio itself is mounted under the seat and can easily be moved to his other vehicle!  Great job, nice install Tom!

 

Seen by Skyler WØSKY on a hike in the mountains!  An APRS solar powered digipeater setup probably setup by Chuck NØNHJ.  I say probably because according to Skyler he is responsible for at least 15 of these around the state!  This is really awesome since APRS coverage in the “hinterlands” (where there ain’t a hint of nothin’) is so very important for emergency APRS use.  Skyler saw this one in the Dillon area.

AND, JUST FOR FUN AT THE END! For all us Engineers!

 

 

My Jinki and Liu Liu LOVED THIS! Thanks to Jim KCØRPS!

 

Well, OK here is my editorial that really has nothing to do with the “Hamshack”, so I will stow it at the end here.   I need to say something about the pandemic going on.  As of just yesterday, the USA is seeing more than 150,000 new cases a day.  There are so many hotspots that I can’t mention them all there, but the information is readily available from many sources, so you can pick the one you trust and go from there.  I have a wife in healthcare, and folks, the medical community will tell you that this is an ongoing and serious issue, and they are ALL exhausted.  So, if you don’t believe the news media, talk to someone in the medical community.  We want to know the real truth and facts, so get it from those who are dealing with over loaded beds and are on the front line.  And as I shared on the SBE SkyHubLink Net, we need to be wearing masks.  If you simply don’t want to for whatever reason, now we are getting word that, as I have really thought all along, it will provide you a modicum of protection for yourself, and especially for those around you, from you!  As one lady put it, I heard last week, “I wear a mask because I care about you.  If you don’t, I guess you don’t care about me”.  By the way, the graph below is just Colorado as of this writing.  34 average deaths per day.  Honestly, I don’t know how I could look someone who has lost a loved one during this time in the face and not think that the complaining and arguments that have arisen between so many can be justified.  Shame on us. We should care about EVERY SINGLE DEATH, more than a quarter of a million at this writing fellow Americans.  Are we really THAT selfish and petty???????  Unfortunately, we have a lot of people making decisions not to wear masks and by that token, are making the decision to expose you and me.   Very sad……..  THANK YOU to those of you who do care.

The KE0VH Hamshack for July 2020

July 19, 2020
By

July 2020

Many things to cover in this addition.  First, the NEW 449.850 AllStar repeater is now on the SkyHubLink full time in Colorado Springs.  Skyler WØSKY and I put it on the air from the “Gardner Rock” site on the southwest side of town up in the foothills.  Thanks to our good friend Vic Michael for allowing us on the site and Dave West of Mountain Country radio for the internet connection.  The repeater has GREAT coverage so far, up and over Monument Hill north of town and south to just north of Pueblo plus out onto the eastern plains.  We have been searching for a Colorado Springs coverage repeater for quite some time and now are able to serve this area with a SkyHubLink connection.   We decided to do this one analog to introduce more amateurs in the area to the SkyHubLink and ease of setup in this case.  More on the new repeater later in the “Hamshack”!

With the thunderstorm and lightning season well underway one of the projects I wanted to accomplish was getting our node radios for the YSF system link that connects the Wires-X linked repeaters to the rest of the SkyHubLink.  And, I decided to homebrew the 449.450 analog AllStar node radio antenna instead of using a vertical that I had employed.  A simple 5 element Yagi plan made from some brass rod and loose molding that I had on hand in the garage junk bin.  I wanted to mount the antenna inside the garage, and since I am line of site to the repeater at 11,440 feet, I really didn’t lose any signal that would have caused problems.  Since the YSF link radio antenna is a professional level 3 element heavy duty beam antenna and is mounted in my attic on the other end of the house from the garage, a little separation between the antenna’s wouldn’t be a bad thing.  In the pictures below you can see the easy construction and how simple the antenna is.  Now there is about 30 feet separation and both antennas are “inside”, so I don’t have to disconnect them during storms, thus losing link node radio service to the repeaters.

The simple construction of the repeater Yagi, cut for the middle of the 5 MHz of the 449.450 repeater output and the input, so it is cut for 446.950.  In the picture blow you can see the simple soldered feed point on the split driven element.  Standard element spacing is used.  And the mounting is keeping with the simplicity of the design.  Mounted to the rafters in the garage and out of the elements, the antenna has been on the air now for about 2 weeks as of this writing and is working well connecting 449.450 to the SkyHubLink system.

The antenna mounted in the garage and the analyzer measurement using a NanoVNA

My good friend and SkyHubLink colleague Mark NØXRX worked this past month on a derelict Heathkit SB-200 amplifier that had really needed a restoration for quite some time.  It had sat on a shelf for who knows how long and was quite in need of some loving care by a good technician.  Mark really knows his stuff, so with that I will let him tell the story of getting this fine amplifier back in operational order.

The AMP definitely was owned by a smoker at some point in its life. It had a lot of smoke residue all over the case and frame. The front light came on when I powered it up, but the tubes wouldn’t. With some simple troubleshooting I found at least two capacitors in the power supply that were bad and a few other things.

I picked up a new power supply with some more modern components and a much cleaner package. Well I had to assemble it.

I replaced the RCA RF input with an upgraded SO-239

I found bad/broken diodes as well. The crystal diode was hard to find and I’m still waiting on it to arrive. The silicon diode I had in my parts bins.

I installed a slow-start relay board to protect the power supply and the tubes. This is a mod from Harbach Electronics. They only provide the parts and I assembled it. The trick was getting a good place to mount it (They don’t provide the mount).

I installed a slow-key as well so I can use it with modern radios like my ICOM IC-7300 and Yaesu FT-991 without the need of an external adapter box. This is also from Harbach Electronics. This was a tight install.

After cleaning everything up this is how it ended up.

Now tubes all work, well the best that I can tell so far. I still need the RF diode before I can start doing other tests.

 

I still need to install a protection circuit for the meter. Apparently, that is the hardest and most rare part to buy so I want to protect it. There are some other mods available, but I think I already have way too much time and money into it so far.

Thanks for the contribution to the “Hamshack” article Mark!  GREAT JOB!  It looks amazing!

**************************************************************************************************

The node radios at the home QTH were originally in separate racks on either side of my operating position and it was difficult to see the 449.450 link setup in the upper right-hand rack due to a computer monitor placement.  With the new antenna setups and the way they fed into the shack where I wanted them finally it was easy to place the two node radio’s and power supplies where I can always see the fronts of the radio’s and the power supplies, plus makes much easier access for troubleshooting any possible issues that could crop up.  This is a project I have wanted to complete for quite sometime so that there would be easier access to the UPS and the network connections.

BACK to Colorado Springs, here are the pictures of the day Skyler and I installed the 449.850 analog AllStar repeater.  Skyler built the repeater out of a Raspberry Pi3, two Motorola radios, and the UREI interface box.  The Pi serves as the repeater controller and AllStar network interface, with audio interfaced in the UREI.

Last week on Lookout Mountain and the 449.625 Wires-X repeater there were several electrical power hits to the site that took out the hard drive on the computer that takes care of the Wires-X functions and links to the SkyHubLink Wires-X room 46361.  Over the weekend I rebuilt the computer using Windows 8.1 instead of the old Windows 7 system, did the system updates, the remote Wires-X system configurations for unattended operation. By the way, be sure to do this on your Wires-X computers as you don’t want updates and other computer functions happening during main usage hours.  You want to make sure that full restarts will take place if power anomalies happen.  Now the system is back on air on Lookout Mountain updated and working perfectly. And dusted!  Speaking of electrical power, see the system below that Jeff AK6OK has set up at his repeater site in Auburn CA covering Rocklin, Roseville, and the area NE of Sacramento CA.

A couple of years ago now I wrote about my 5BTV vertical tilt over mechanism that I built from a couple of pieces of angle iron and bolts with wing nuts.  This has been a very beneficial and inexpensive way to have a much easier time repairing and maintaining my vertical antenna.  I also had previously modified the antenna for 12 and 17 meters by adding wires fed at the bottom of the antenna and supported by PVC spreaders attached to the antenna after reading about them in another article.  Well after a few years, the antenna needed some repair and attention as one of the “spider” elements between the 20- and 40-meter sections of the antenna had broken and fell. The wire antennas had fallen too with the top spreader support. With the addition of the mounting scheme you see below, repairs to full operation only took a little while with the addition of my tilt over homebrew mechanism.  The two top wing nut bolts are the vertical supports, the bottom is the pivot point.

The tilt over mechanism that pivots on the bottom bolt next to the feed line in this view.  The two red wires are the 17 and 12 meter ¼ wave wires.

The antenna tilted over for repairs.  You can see the pivot point mounted to a pole in the ground on the right.  Below is the mounting point for the “spider” element of the antenna.

 

The “Spider” element repaired, and the top spreader secured in place for the wire elements for 17 & 12 meters.   Below another view with the suspension lines in place on the PVC spreader.

The repaired antenna back in its upright and locked configuration and new suspensions for the 17- and 12-meter wires.

The KE0VH Hamshack for June 2020

June 21, 2020

JUNE 2020

Greetings all, happy Summer and June! Even with the Covid virus still among us, let’s think about others and the possibility that we could possibly encounter it and even carry it to those whom it could be really bad news. I am approaching 60 in September, have had cancer (emphasis on the “HAVE HAD”, thank the LORD!) in the past and am entering the age group of higher risk. I am still wearing a mask around others out in public and will continue to do so until they come up with the vaccine. Let’s really care about those around us and help keep us ALL safe!
Just a personal note.
**************************************************************************************************
SO MANY things to write about and update you on about the SkyHubLink System. (www.skyhublink.com)
As of this writing, I would like to emphasize the following about protocols that I have been asked about regarding operations on the SkyHubLink system repeaters. From the webpage:
IMPORTANT OPERATING PROTOCOLS & PROCEDURES. We ask that as you are using the system on one of the associated repeaters that due to digital linking, please leave a 5 second space between transmissions to allow someone on another mode or repeater to be able to break in. It also helps if you hold your PTT key for about a half second after you speak your last syllable, so that you won’t be “cut off” with your last word. Ask frequently if there is anyone else who would like to break in or join the conversation. Being too tight with the PTT can exclude someone trying to get in from another mode. Don’t be quick on the PTT trigger as it were, or others may not be able to join in. While we encourage longer fun rag chews on the system, but it is important to observe this operating practice to allow others to join in or in case of any urgent or emergency traffic from another mode. AND, if you have more than 2 people it is really important to set up rotations of operators so that digital collisions and no one being heard won’t be a problem.
ALSO, it is very important that you do not “KERCHUNK” the repeaters on the system. This causes issues with the BRANDMEISTER DMR links and will lock out the DMR system which is bridged into the AllStar system. Please do a full call and ask for a radio check if you are testing or just simply want to check if you are “making the repeater”. The DMR and Fusion repeaters have virtually no squelch tail to hear. Thank you for your attention to this matter.
Now we on the air with the 446.275 Simplex node on the NØAMY (Tony) YSF Reflector 92722 in Colorado Springs full time on the SkyHubLink. It covers the central part of Colorado Springs very well as you can start hearing it on Monument hill on I-25, and we are going to drive the signal as we can to determine full coverage at this time.

 

NØAMY’s node antennas for UHF and VHF, the control point for all, and his AMAZING monitoring rack for just about all frequencies and modes! WOW! GREAT STUFF TONY!

 

 

The NØAMY front yard TOWER (YES, the tower lights work!) and the 446.275 Raspberry Pi/MMDVM Pi-Star setup with the Motorola MCS-2000 data radio comprising the node for Colorado Springs on YSF 92722 US SkyHub Denver SkyHubLink. So, when in Colorado Springs get on the node when you can!
**************************************************************************************************
Myself, Mark NØXRX, and Lee NØVRD have now put 448.400 on the air from just NW of Parker Road and I-225 in Aurora on the allocation of the coordinated frequency that our good friend Cliff NØZUQ had on the air for a long time, but has been silent now for several years as Cliff lives in Colorado Springs and hasn’t been able to look after the system. So essentially I took it over with his blessing, and re-coordinated the frequency pair to the with the CCARC (Colorado Council of Amateur Radio Clubs Frequency Coordination Database)( https://coordination.ccarc.net/cgi-bin/ccarc/main) Then I got together to put it back on air along with my aforementioned buddies with a Yaesu DR-2X repeater to cover the southern area and east where we weren’t solid with the other repeaters. We spent a Saturday putting together the antenna and mounts and getting the repeater in a rack having a great time! It was a VERY windy day and a front that later that afternoon brought in some pretty heavy thunderstorms, so we got the work done with time to spare. Matt KEØLNU way up in Coal Creek Canyon, about 33 or so miles directly to the NW of Golden helped us test and was able to successfully get into the repeater from his QTH on an omni directional antenna. We are putting out 50 watts TPO to the Diamond X50 antenna about 165 feet or so above the ground on the 12-story building. So far as tested it has great coverage to the east, northeast, and even west along C-470. We still have coverage testing to do for other directions, and I could also get on it north of Denver on hilltops along I-25 when driving to Cheyenne one day. We are still working on the linking system as it will be connected via an internet link directly to 448.350 on the west side of town using the Yaesu IMRS (Internet Multi Repeater Site) linking functions. Since 448.350 is using an FTM-100 node radio to connect to the SkyHubLink Wires-X room 46361, this will allow both repeaters to still connect to the rest of the SkyHubLink as you cannot use an HRI-200 Wires-X controller and IMRS on the repeaters simultaneously. Here are some pictures from the site and the work done to get the system on the air!

The repeater is in Fusion digital mode only. We will announce via the email list when the final connection is made, and the repeater is on the SkyHubLink. By the way, this one will not be Wires-X steerable. It will be locked into SkyHubLink as its parent repeater 448.350 KDØSSP is. For those of you who want to operate on other Wires-X rooms remember 449.600 NØPUF/R on Warren Mountain serving the south metro area and 449.625 KEØVH/R on Lookout Mountain serving north and northeast are steerable to other Wires-X rooms. HAVE FUN! OPERATE and use the system!

Mark NØXRX and Matt KEØLNU have had some interesting projects going on recently that I wanted to share here in the “Hamshack”! First Mark has been working on a mobile ham station in a trailer that has morphed into his office space at home during the “stay at home” times we all have experienced. His trailer is air conditioned or heated depending on the need and can do the dual function with ease and comfort. This is a developing story, so stay tuned as we are looking forward to further developments and hey Mark, lets head out for field day one day soon brotherman!

Mark NØXRX, the trailer, and below the hamshack/office inside

The equipment wiring and rack at the rear of the interior, and the front with cabinet space and “workbench”

And onward to Matt KEØLNU’s Jeep and ham radio project. Matt is getting ready to do some 4-wheelin’ with ham radio onboard of course. He is using his Kenwood G-707 dual band mobile rig cleverly mounted in the jeep above head and control head in good view. GREAT JOB MATT!

KEØLNU Ready for some adventurin’ in Colorado!

KE0LNU’s G-707 radio is mounted in the box above left. In the right-hand picture, you can see the copper wire making up his antenna for reception of broadcast stations for the Jeep. Rather clever, I think! Great job Matt!

Summertime on the backyard patio at my QTH is one of the most relaxing and enjoyable things that I love. The Monday Night SBE/SkyHubLink net there is a fun and pleasant time for me during the summer. This year, I have my backup/extra Yaesu FTM-400 that see duty when I set up and test emergency generator, power supply, radio and I-Pad out on the table. Running the NET from there is something I will be doing a lot of this summer for sure! I can monitor both the Fusion 448.350 and analog 449.450 repeaters easily this way.

And there’s Jeremy N6JER checking in via hotspot, and AK6OK Jeff, on the K6IOK repeater in Auburn.
Both in Rocklin CA, note the mileage to the stations from KEØVH. Another feature of Fusion equipped radios.

Hey maybe my good friend John Bissett at RadioWorld would like this for his Workbench article. Need a cap for an NMO mount without an antenna, check out this idea!

1. Drink the Gatorade. 2. Take some electrical tape and make a cap for the NMO mount! 😉 3. AHHH!
Finally, this month, while watching a movie on NETFLIX (I forgot what at this time) I saw this old VERY RARE Bomber version of a Zenith Transoceanic Model 7G605, circa 1942. Beautiful examples like this movie prop are extremely rare in such condition and just rare anyway, plus commanding a high price. Great movie prop for a period movie for sure. Snapped the picture off my TV while viewing the movie.

The KE0VH Hamshack for May 2020

June 20, 2020
By

Greetings all! I hope this month finds you safe and well, and that this whole ordeal hasn’t been too bad on you and your family. I pray for all those so severely affected and I hope you do too. Lets help out those we can when we can and keep each other in prayer and care!

I have been having a ton of fun with FT8 on just about all bands over the last couple of months. I have worked more than 200 stations on all the bands on this really fun digital mode. I have also worked countries that I never have before, including a Ukrainian maritime mobile station. Absolutely fascinating what comes up on your WSJT-X software screen. It was SO EASY to interface with the FT-991A and its onboard soundcard. Plus I am doing Winlink email via VHF and the soundmodem software and Winlink Express. Here is a sample of my logbook loaded onto QRZ.com as of this writing:

Lots of fun to be had with the very exciting and easy to get on mode.

And another exciting evening back in April! Literally around the world!

I have yet to work the Mongolian station I heard on recently but will keep trying of course!

Brad, KEØLLH who is a member of the FrontRange6Meter@groups.io that I am also a member of, has built this really nice 6 meter dipole for doing FT8 and meteor scatter here in the Denver area. This group actively spots band openings and different mode communication abilities and shares via email as events occur. There have been some exciting openings on 6 and 10 meters lately, even some on 2 meters. If you are interested, I would encourage you to check out this fun forum!

Here is another antenna idea from the group! A nicely made 6- and 10-meter combined antenna.

WOW! What a GREAT MATCH!

*************************************************************************************************

Talking to Cris W5WCA via FUSION recently.

***************************************************************************************************

And now the latest with the SkyHubLink System!

We are actively working on getting the Warren Mountain 146.88 analog repeater on the air via AllStar here as soon as possible but have ran into some issues as far as the repeater being able to solidly hear the link radio from a remote site yet to be determined. More on this as it develops. We have decided at this time to keep KEØVH/R at the Lookout Mountain site and possibly put another repeater to be determined at the Milner site above Loveland. Our good friend Vic Michaels, a ham himself although inactive, has been very accommodating to our ham group in allowing us to be on his site on Lookout Mountain and to be able to put a repeater at Milner. This would give the SkyHubLink continuous front range coverage from Monument Hill to the Wyoming boarder. We also are grateful for Daryl W3ORR for the Wires-X simplex node in Cheyenne. We hope one day to be able to utilize Daryl’s node to connect to a Fusion full repeater in Cheyenne. We also hope to have Eldorado Mountain’s 447.175 from the CRA connected into the SkyHubLink soon. This would provide that coverage fully north of Ft. Collins and a good coverage of the Boulder “RF hole”. That would really be exciting to be able to do. We have a simplex Wires-X node in the Dillon/Silverthorne area via the N5SKH-ND system thanks to Steve N5SKH. It doesn’t cover a lot, but we hope to expand that sometime soon too. AND, soon Glenwood Springs, Rifle, Carbondale, and probably almost to Aspen will be covered via Wires-X with Andre’s NØSWE Fusion repeater. This will literally then make the I-70 corridor from Denver to the Utah State line coverage complete for the SkyHubLink.

******************************************************************************************************************

ANNOUNCEMENT!

******************************************************************************************************************

We are excited to announce too that now the SkyHubLink has two new affiliate partnering repeaters to add to the group! The first is the Andy’s AllStar Akron Colorado based NØSTY repeater on 449.925 MHz, 100 hz pl. It covers the town of Akron and about 7 miles out currently. Also welcome to our new friend Jeff AK6OK, and the Fusion Wires-X repeater on 147.360 that covers a HUGE area NE of Sacramento CA, including all our EMF/K-LOVE friends and fellow hams/engineers around Akron CA and Rocklin CA! I am more excited about this than I can tell you! 😊 The repeater site above Akron CA is really cool, as you can see in these pictures:

The site also has a fully remote-controlled HF Station! See Jeff’s webpage at https://k6iok.com/k6iok-repeaters for all the information on what they are doing there!

A panorama of the view from the K6IOK site and below some of the “residents” that live there, no kiddin’!

 

And below you can see Jeff and one of his friends during a site visit! Nice companions while you work on the repeater systems right Jeff? 😊

Maybe another ham hangin’ with Jeff????? No, wrong animal……..

Coverage for AK6OK FUSION Wires-X, now on the SkyHubLink

A busy day on the SkyHubLink! What’s the use of quiet repeaters? No, really!!!

And the Wires-X Connections into SkyHubLink

In the above picture of the Wires-X nodes, you see at this time that, in order left to right, are the Dillon simplex node, 449.625 KE0VH-repeater on Lookout Mountain above Golden CO, W3ORR simplex node Cheyenne WE, 448.350 KD0SSP repeater in Lakewood CO, the Rocklin CA K6IOK repeater, and the 449.600 Warren Mountain repeater above the SW section of the Denver metro area. This then links into the rest of the system via the YSF Radio node at my house that is on the 448.350 repeater frequency and then via internet into the SkyHubLink server. The diagram below lists the primary backbone system of the SkyHubLink.

More system news: From up in NE CO, Danny NØPRG is working along with his guys on their system that will also be linked in soon. Look for coverage for Steamboat Springs, Craig and another link, probably DMR into Grand Junction. That will be coming up this summer and check back in future editions of “The Hamshack” for more information. We are also hoping that our good friend Andre NØSWE will get his Fusion Wires-X repeater on the air as soon as the road becomes passable up on Sunlight Peak above Glenwood Springs. It will cover a massive area from Eagle CO to out near

 

Also I will send out information on the email list as it becomes available. If you would like to be on the list but are not at this time, email me at ke0vh@outlook.com. By the way, I need to thank folks for the help, maintenance, and connections that make the SkyHubLink system possible:

And, it you are an Anytone DMR Radio user, we have a SkyHubLink member who is our resident “expert” 😊. Tim KAØAAI writes his own codeplugs for these radio’s and really knows them well. Email or text me at 303-704-3290 and I will put you in touch.

 

Seen at a LOVE’s Truck Stop near Cheyenne. Any idea what kind of antenna this is? I was going to ask the guy, but he was on the phone the whole time pumping gas and then quickly drove off!

Using the mobile hotspot linked thru the cellphone to the SkyHubLink in Colorado City CO talking the Dayrl W3ORR in Cheyenne. Love the Fusion feature of being able to see distance to station you are talking too. VERY COOL!

Watching a war movie on AmazonPrime one evening, look at this jewel that was a movie prop! A VERY RARE Zenith Transoceanic BOMBER model 7G605 (circa 1942). A working good condition model is a real treasure! I’ve only seen one in real life at an antique store and it was in awful condition but still very expensive. When restored and operating, I don’t even want to know what the price would be! 😊 See a video about this radio at: https://www.youtube.com/watch?v=ddi0QtwjCJE

AND FINALLY, AMEN!

The KEØVH Hamshack for March/April 2020

May 23, 2020
By

March/April 2020

Greetings from Wheat Ridge CO. Yes I too have been working from home in the KEØVH Hamshack / Eastern Colorado “mini NOC”. I hope this finds you and your family safe. There is absolutely no more important thing that we can do right now than to do everything we can to keep our families, and others, and ourselves safe from this virulent pestilence that is effecting and infecting our entire world right now. We need to really be aware of and deeply caring of our neighbor as our Lord asks us to be. Let us really follow the guidelines to protect all those within our sphere of influence. And to help out those in need when and where we can.

The KEØVH Hamshack in “EMF Engineering” mode! During a meeting, via remote facilities!

Its actually been a lot of fun working at home. Its amazing to me how these days everyone is finding out the different ways to work remotely and make everything happen. Cudos to our IT crews at EMF and the Engineering department for making it work. It has been so wonderful to see my fellow colleagues around the country via our remote connection facilities. The people and company that I am blessed to work for and with, and my amateur radio community friends have blessed me beyond measure. I am wondering how all of this will manifest itself in the future for people who can work remotely and how as this crisis has made certain things absolutely necessary, how it will possibly make changes to our society. Will some businesses change and will working remotely, schooling remotely, seeing our doctors remotely become more of whatever the “new normal” might be? It will be interesting to see how the next couple of months and even year plays out. And please lets remember to pray for, support where we can, and be friends, real friends to our neighbor in need where we can. So many are suffering HORRIBLY during this time. More on that later.

This is one of my favorite internet things ever. Want an idea of how small we are in the Universe, or how LARGE?

Then take a look at this site:

https://scaleofuniverse.com/

Its been around since 2012, but is still mesmerizing and profound:

If you have some good rope, here’s a trick that might just get you home when you get stuck in your vehicle. Thanks Sam!

IF you are using a hotspot for digital radio communications, it is VERY IMPORTANT to keep up with this

https://amateurradionotes.com/pi-star-updates.htm

 

The latest update as of this writing is in the upper right of the above is:

Be sure to do this…..often! New nodes and improvements in the software are available frequently.

And thanks to my good buddy Kenny K4KR for the great picture here of his VERY NICELY laid out shack. Here you see his WSJT-X software running and interfaced with his FLEX 3000 Radio system, and using AC Log from N3FJP. And I have just started using the logging software myself. It is a really cool system that will interface with your radio and various software systems like WSJT-X. It keeps up with your contacts, possible awards earned, and all those great features such as uploading to LOTW and EQSL. If you would like to learn more go to the website https://www.n3fjp.com/aclog.html

Below are pictures of KEØVH operating WSJT-X on the FT8 mode using the same software as Kenny but interfaced to my Yaesu FT-991A. A single USB cable from the computer to the radio’s on onboard USB connection and onboard soundcard makes the digital modes extremely easy. The Yaesu system uses its own software drivers for the USB port setup but it is really easy and quick to do. If you decide to do this with your FT991A and need help don’t hesitate to holler at me! Or you can call on the phone, or SkyHubLink!

Here you can see my open AC Log, and WSJT-X operating the Yaesu FT-991A

Operating on 6 meter WSJT-X FT8 mode. Was pretty dead when I took this picture, so I went to 15 meters and contacted quite a few stations in north and south America. And, using the https://pskreporter.info/pskmap.html website I was able to see everywhere that heard me. This is a really remarkable site that listens for communications on the ham bands and can show you in real time where your signal is being heard! SO COOL! Here on this map you can see where KEØVH’s FT8 signal was heard on 20 meters (with hour stamp) one afternoon (17 hours ago when I pulled this picture). West coast of Africa, Hawaii, Japan, and out of the shot a New Zealand and Australia monitoring stations received my signal!

Pi-STAR UPDATES VERY IMPORTANT!

 

IF you are using a hotspot for digital radio communications, it is VERY IMPORTANT to keep up with updates for your

Pi-Star. This will enable you to of course in additions to the latest updates for nodes and operations,

https://amateurradionotes.com/pi-star-updates.htm

 

The latest update as of this writing is in the upper right of the above is:

Be sure to do this…..often! New nodes and improvements in the software are available frequently.

AND, Skyler WØSKY is at it again!

This setup is a couple of Kenwood TK-88 type radios that Skyler is building into a repeater that will be deployed on the SkyHubLink.com system in Akron CO for our friends Andy NØSTY and Corey KEØHFK to be on with us (plus others in the Akron area). Corey has a tower and antenna already at his home on the south side of Akron and it will be great to have them join us on the system.

I guess Matt KEØLNU had a bit of snow at his place up in Coal Creek Canyon NW of Golden. Enough to almost bury his mobile antenna for the Yaesu FTM-400xdr. Matt is that your car under there? HOLEY MOLEY!

Hello Cris W5WCA via my C4FM Yaesu FT-3207D!

 

AND, while I am at it, here are several articles about ham radio “social distancing”!

 

https://gardnernews.com/ham-radio-operators-practice-their-social-distancing-on-air/

http://www.arrl.org/news/ham-radio-clubs-connect-amid-social-distancing

https://www.newsobserver.com/news/coronavirus/article241608001.html

 

😊 It was noted by one ham on QRZ.com that he preferred 40 meters! 😊
