The KE0VH Hamshack for February 2018

March 8, 2018

Greetings, Happy February

Lots of pictures to show you this month. So let’s get started!  BE SURE to see the last story though!  It is a real kicker!

 

OK!  I did it!  Last of January I passed the Part 107 Remote UAG Pilots Exam!  I am really excited at this accomplishment and look forward to operating both my and the company’s DJI Phantom 3’s for fun and for work.  Thanks to Sam and Jeremy for the help and encouragement in getting this certificate.  There are a great many study materials available on Amazon.com and the apps on the I-stuff.

There are a lot of rules pertaining to flying drones both as a recreational hobbyist and for commercial use such as inspecting towers and other tall structures, real estate, etc.  A lot of people for instance on YouTube are posting videos that are just downright dangerous and even reckless without understanding and adhering to the FAA rules about airspace and safe operation.  And of course in todays world there are apps that you can have on your phone to assist you in know where you are in the National Airspace, altitudes to safely (and legally fly up to) operate your drone.  See the FAA’s “B4UFLY”.  For instance there is a drone ceiling rule of no higher than 400 feet above ground level, unless flying within a 400 foot radius of a structure, then NO higher than 400 feet above the highest point of that structure.  You must notify airports and heliports of your flight if within 5 miles of said facilitiy.  NO flying over people unless they are inside a structure or automobile unless they are part of “your crew”.  VLOS, which means “Visual Line of Site”.  You must be able to see your drone with the naked eye, no binoculars for primary visual tracking, etc.  So on an so forth.  Even with a lightweight drone.  So before you fly, do know what you are doing!  I recommend 2 study guides that I used, check this link to amazon:

https://smile.amazon.com/Remote-Pilot-Test-Prep-2018/dp/1619545594/ref=sr_1_1?ie=UTF8&qid=1517499493&sr=8-1&keywords=remote+pilot+study+guide

“TestPrep” is only around $14, and INCLUDES 5 online (very accurate) practice tests.  The other app on my Ipad I used is called “FlighReady”. It costs around $24.  But with these I was ready to go.

After passing the test at an FAA facility here in Denver at Centennial Airport (registration is fairly simple but can be confusing), you must then apply for the license via the IACRA FAA website.  That again took a little understanding from the FAA “helpdesk”.  I have the official directions on what to do so email me if you would like a copy.

!  Check out this video of a 737 flight simulator that a guy in Britain built in his outside garage.

And this inside a garage!  Pretty amazing!

I made a ham radio shack video a few years back, you can see an old version of “The KEØVH Hamshack” in this video on YouTube from 2008!  See it at https://www.youtube.com/watch?v=kHhLYk7BiSU at about the 3:05 point in the video.  Everything there is long changed out except the D-104, the code key and headphones, and the Heil mic!

Here is the KEØVH AllStar Node 46020 in the Lakewood office.  Keeping in touch with hams across the country directly via the simplex repeater here.  Holler at me sometime via the node.  Shane KØSDT has a node up and operating soon.  We continue to grow this system and as you can see here it is connected to the Sky System hub node 46079 which in turn is connected to several other nodes, including the N6JER system in Rocklin CA.  If you have any questions or need some help setting up your own node let us know.  You can use an older computer or a Raspberry Pi and downloadable images to get started on your node.

And here is Skyler Fennell KDØWHB , our AllStar guru and EMF Contractor talking to the NOC and calibrating one of our stations in Colorado.  Skyler is a great help for all things AllStar, and runs several nodes including the KC5ORO Socorro New Mexico node where he is a student at the university there.

I found a buyer for the 1954 Admiral TV that I have had for a few years that came from Glenn, WNØEHE for myself and Greg WB7AHO to restore.  Greg did a great job in replacing tubes, capacitors, and doing alignment procedures to get the set operating and fully functional again.  The TV now has a home outside of Phoenix in a home that is dedicated to all things 50’s!  No kidding.  The new owners were so excited to find this set and I am really glad that it will actually be used (I sent an HD converter box with it) at its new home.  Will post pictures of it in its new home when they send them.

Greg doing some final tune-up and adjustments on the Admiral

During our 2018 Engineering Summit at K-LOVE HQ in Rocklin, we had the opportunity to go to classes for various pieces of equipment we use and great follow up information and updates for our technical resources.  Steve Wilde, who is our transmitter and antenna expert, and who is in great demand around the country for high power transmission operations was on hand to teach a class or two on using the Field Fox Cable/Network/Spectrum analyzer.  Very informative and educational from essentially the ground up on the extremely useful and portable tool.  Thanks Steve!

Basic Field Fox Op’s

High power transmitter operations, tuning, and troubleshooting the PA circuits

I love watching some the shows on Netflix especially when you spot radio gear in the scenes.  Here are some more great pictures of gear used in the programs.  These are from the show “The Crown”.  Note the microphone the Queen, played by actress Claire Foy is using at an address being given in one of the scenes:

You know this one, an Astatic D-104 in a suspension mount.

From the series “Stanger Things” on Netflix, a Heathkit (I believe a DX-60 Phone & CW transmitter)

A Heathkit speaker/PS, the DX-60, an HG-10 VFO for the transmitter, an HW-16 CW Transceiver,  and a GE Desk mic

Unsure of course why they teamed up a transmitter and transceiver, other than to just look cool!  J

By the way here are some more pictures from our engineering summit.  Here is my portable AllStar link that using my hotspot in my cell phone, I was connecting to the WØGV repeater in Denver where I talked to Jim KCØRPS, Gerry WØGV, Matt KEØLNU, and connecting into the KC5ORO AllStar repeater in Socorro NM had a nice chat with Skyler KDØWHB.  The system worked well, and Shane KØSDT had his portable link in his hotel room across the hallway checking it out, and of course I had to help him test it!

The Baofeng UV-5R handheld that is my general carry around HT, and the portable AllStar Raspberry Pi3 and Yaesu FT-170 that is my 2 meter “node” radio.

 

By the way, here is “professor” Shane KØSDT, teaching a class on our remote control system at HQ during our engineering summit!

And also from HQ, a Pano picture of the engineering “museum” of old network equipment:

Split into two pictures, note the Sparta Mixer on the right and the tower section top picture.  YES, it LIGHTS UP!

 

I just HAD to share this with you.  EMF Engineer Mike McGregor had to come up with an absolutely outstanding solution to come up with an answer to a perplexing problem experienced recently with the installation of a used transmitter building enclosure at a site in his area.  The building was bought used and had no tubular framework or supports on the lower side of the building for the crane lines to go thru after the building was lowered into place.  The lines from the crane supporting the building are very expensive, and the crane operator didn’t want them damaged or destroyed as the cost would have been enormous.  But when they lifted the building over the foundation to set it down, there was NO WAY to remove the lines.  This presented quite the dilemma!  What to do about this?

The building being lifted off the transport.  Note the lines on the flat building bottom!

Uh OH! There’s the problem!

Well, you can remove one cable, but not the second one.  2×4 isn’t the answer, hmmmm…..

So Mike and his crew came up with an ingenious answer, apparently hearing that ICE would be usable in bags and when it melts would of course since the building was in place on one side, would then lower the building into place.  SO, Mike and his crew went and bought bags of ice, and here you go!

A couple of hours later:

Cable is removable now!

Going DOWN!

LOOK AT THAT!  PERFECT!

 

SUPER KUDO’s to Mike and his crew!  What do you bet that could be used again?

The FINAL setup, in place perfectly and ready for equipment!

 

A new service from our favorite airline? J

The KE0VH Hamshack for January 2018

HAPPY NEW YEAR!

 

FROM Colorado Public Radio

http://www.cpr.org/news/story/this-radio-station-helps-colorado-seniors-dial-back-the-years

Thanks to Jim, KCØRPS for this link.  A senior living radio station at a facility here in Denver!  What an absolutely wonderful idea!

 

Well I am getting on studying for the FAA Part 107 Drone Pilots license.  Back in December I ordered the “2018 Remote Pilot Test Prep 2018: Study & Prepare: Pass your test and know what is essential to safely operate an unmanned aircraft” from Amazon.  At only $13 it is quite a buy and easily available.  To fly a drone commercially you must have a FAA Part 107 certificate.  At EMF several of us field engineers are prepping for this so that we can fly aerial missions around towers and sites to help find problems with towers and antenna’s, and to survey sites and the like.  This is really fun and to that end I am even buying my own DJI Phantom drone.  More on that next month!  I can’t wait to post some of my own video and pictures here in “The Hamshack”.  If you want to take a look at the book with all supplements supplied Plus 5 FREE online practice tests you can go to:   https://smile.amazon.com/Remote-Pilot-Test-Prep-2018/dp/1619545594/ref=sr_1_2?ie=UTF8&qid=1514918117&sr=8-2&keywords=2018+pilot

 

Yours truly (under the direction of Remote Pilot in Command) Jeremy, N6JER near Roseville CA, getting the DJI Phantom 3 ready for flight and just after takeoff in a hover

The Colorado State EAS plan has long been in need of an update, and with so many stations changing call signs, frequencies, new stations coming on there are a lot of discrepancies in monitoring assignment and is quite confusing these days.  According to CBA president Justin Sasso, “In 2018, the CBA will call on broadcast engineers, in each region, to submit changes and edits to their Local Area Plan.  The CBA will start by addressing one plan at a time and edits will be made based on the input we receive from broadcasters within that area plan.  Once the edits are complete they will be submitted to the FCC for approval.  Upon FCC approval, we will update that plan online.  Unfortunately, parts of the State Plan are made up of older documents that may require hand transcription, so we can edit the plan moving forward.  While we’re calling on broadcasters to update their area plans, the CBA will begin the process of converting each plan into an editable document, so future changes can be made with greater ease.  While the State Plan outlines other emergency contacts and information, the CBA’s initial goal will be to update the broadcast portions of the Local Area Plans first.  Other areas can be addressed at a later date, once this initial clean up attempt is complete.  We look forward to getting this task underway and appreciate the cooperation of Colorado’s broadcast community in advance.”

We will be having a local Denver SBE Chapter meeting on this, probably in February, I will announce that via an email to our SBE NET email list, and you can watch for it at: http://www.smpte-sbe48.org/ Please, if you can attend this in Colorado “about EAS” meeting we would really appreciate it.

The “Hamshack” in Flight Sim mode.  Note the GPS on the small right hand screen and the airport info on the left screen

The table below (Thanks Jim KCØRPS) was produced by a free web site: www.tvfool.com , a very powerful web site that uses the FCC and USGS databases and the Longley Rice algorithm to predict all television stations that can be received at a specific address and the quality of that signal based on the appropriate VHF/UHF antenna at the viewer’s home.  The nature of digital is it is perfect or it is not so let me help explain the numbers for your home:

  • The real channel column is the physical channel our signal is transmitted on.
  • Virt is the virtual channel you select by remote and displayed on your screen. Channel 4.1 is actually transmitted on channel 35.  The significant issue is that channels 2-6 do not work in digital and those channels were relocated to the UHF spectrum; channels 7 & 9 returned to their original high VHF assignments; therefore you must have a VHF/UHF antenna to receive all local signals.
  • Looking at the table below the NM column is the power in decibels over noise; this is a logarithmic function where an increase of 3 dB equates to double the power delivered to the TV.  For your TV to decode a digital signal you must have an NM number higher than 14 dB; we are at 0.8 dB; not a receivable signal.
  • The next column Path where having LOS (line of sight) is optimum for receiving our signal.  1 Edge is relating to single edge diffraction and 2 Edge is a multiple edge diffraction both causing significant obstacles to receiving an adequate signal.  (see graphs further below)
  • You can look at your data for your location at: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d513442bbba0129

 

Take a look at this, really COOL!  Live Weather: www.ventusky.com/ this site shows so much more than a standard weather map.  All kinds of weather data, including clouds, wind speeds, air pressure, snow cover, etc.  REALLY USEFUL!

I also have a node template I can send you if you want an example with just a few changes.  I would be glad to help in this in any way I could.  And in the last August “The KEØVH Hamshack” article you can find details on my hardware and setup for a portable AllStar node.  See it at http://www.ke0vh.com/hamshack/archives/TheKE0VHHamshack201708Aug.pdf

 

AND, to have a backup generator on site, good idea or not?  Read about it here:  http://www.radioworld.com/article/standby-power-basic-equipment-or-boondoggle/222769/  Now, I think that having these available are a CAPITOL idea!  LOL!  (Funds for sure!) But we need to stay on the air, so when you can, it is definitely the way to go!  Interesting reading at the above site.

Merry Christmas Everyone!

This was very cool!  A picture from a show on the Rocky Mountain PBS program “Colorado Experience”.  This is showing paleontologists from Colorado Mountain University in Gunnison Colorado looking at a dig site from the mountain above Gunnison where we have a transmitter site!  There are facilities here from Colorado Public Radio, various two way facilities, and one of ours too.  We are in the building on the right.  Been there many times.  I always had to let the University know when I was going up the mountain being careful to stay on the “road” when traversing the site.  Here is the reason! Cool to see it on TV!

Colorado Mountain University Paleontologists at the dig site on the “W” mountain above Gunnison Colorado.  Picture from my TV during the show.

From Chris Scherer at the SBE National office:

WW1USA Radio
Since debuting in 2014, amateur radio special event station WW1USA has reached more than 13,000 people in more than 60 countries across the world. This occurred as the ham operators were back for the final operation of the year for 31 consecutive hours on Saturday-Sunday, Oct. 14-15. Learn more about this incredible worldwide effort!

https://www.theworldwar.org/amateurradio

As written in previous articles, I love seeing old radios and trying to identify them in movies and TV Shows.  So here are some pictures from the 1st James Bond movie, “Dr. No”

 

This is a K.W. Vanguard Shortwave transceiver, as you can see on the website

https://rigreference.com/rigs/3531-K_W_Electronics_Vanguard

Note the amateur bands listed on the upper right hand of the VFO dial.  The website notes this was used in the Bond movie.  Interesting that they didn’t need the receiver rig on the right to be accurate.  Any ideas on its identity?

The lady above of course didn’t survive the next 5 minutes of the movie as she was eliminated by the bad guys in the movie.  She was trying to communicate with the British Intelligence center in the right hand picture.

Any idea what these radios are?

Very cool to see these radios.

 

 

 

 

More radio’s are featured in the Netflix show “The Americans” which is about Soviet spies living as regular Americans with families, jobs, and basically a “normal” life in Cold War era Washington DC, while carrying out espionage and covert operations as KGB spies with the FBI and other agencies.  They have been using ham radio’s and shortwave receivers in this series to show them communicating and receiving communications from “The Center” (Moscow) for their operations.

A Yaesu radio set to the 2 meter frequency of 145.00 mHz seen from “The Americans”.

I actually own one of these!  A Zenith Royal 7000 being used in the show.

I am in the process of studying for my Remote UAS pilots Part 107  license so I can fly a drone around towers for inspections and seeing what is going on up there!  Jeremy N6JER obtained his last year and EMF has bought several drones of the DJII Phantom variety to be able to do our own tower inspections.  You must have the certification to fly a drone for commercial purposes and have the knowledge to know when and where it is safe to fly.  I basically am studying all the information you must know to basic airman facts and laws.  I am learning how to read sectional charts and weather METAR information, and know what is required to safely operate a drone under these requirements.  Very interesting and fun.  As a supplement and to learn practical application too I am flying my Flight Simulator 9 (2004) again.  This is fun of course and really interests me as I am learning all about flight I can.  I have been flying a Southwest 737-300 around the country planning flights and using IFR.  Learning flight characteristics, weather, and how to use navigational aids is absolutely fascinating.

And yes, I can even land the doggone thing very well.  I have only made my “passengers” sick a few times!

Flight Simulator picture of a 737-300 landing

If you would like to see what is required for a Remote UAS certificate you can look here:  https://www.faa.gov/training_testing/testing/acs/media/uas_acs.pdf

We have finally brought 449.625 the WØKU (IRLP at this time) repeater online for the Monday night SBE Chapter 73’ of The Air VHF/UHF Net along with WØGV thru the AllStar and Echolink system.  Skyler KDØWHB has made all the links possible thru his AllStar Skyhub system, basically a computer that acts as a linking system for the various nodes that can connect together.  Very similar to an IRLP reflector.  The WØKU repeater has one of the best audio sounds on a ham repeater I have ever heard. Scott WØKU and Tracy KIØHC worked hard over the Thanksgiving weekend to get the IRLP link working thru Tracy’s network connection and were successful after a few hours work.  Scott connected into the W4YI IRLP/AllStar repeater in Chattanooga Tennessee and talked to Kenny, K4KR and all systems were working perfectly.  The nice this thing about the W4YI repeater is that it is capable of simultaneously connecting into the AllStar and IRLP networks.  So when we connected into the W4YI repeater link via IRLP it was already connected into the AllStar network where WØGV was already connected, so the entire system was linked up between the various repeaters.  Very cool system.  We do in the future hope to put WØKU on AllStar too. AND, you can see all of this on the AllStar “bubble” chart internet feature.  Email me for more information on this.  AND, be sure to try to join us via Echolink too.  Details are at:

Once again, my new email address is now ke0vh@outlook.com.  I have changed it due to some problems with access and my cell phone.  Please make a note of it!  J

Thanks to my buddy Chris, WXØPIX for this information:

Long Island Ham Radio Operator Helps Relay Messages From Hurricane Victims In Puerto Rico – CBS New York https://www.google.com/amp/newyork.cbslocal.com/2017/09/22/ham-radio-hurricane-maria/amp/

Hurricane damage and OSHA violations!  J

Several humorous statements from the guys who posted these pictures such as “Can you hear me now”? and “just adjust the picture as so and the tower is plumb!”.   Wish I could claim the brainpower for those captions.

Well I am back from my trip to the Chattanooga TN area to visit my Mom and stepdaddy Lester.   Had a great trip on the Vulcan!  I used the AllStar phone portal to keep in touch with guys back in Denver and Kenny K4KR in the NW GA area as I went and came back.  I ran into thunderstorms on the way out near Paducah KY and then storms and COLD rain on the way back around Colby KS to Denver the next weekend.  I used the AllStar phone portal and took my Baofeng HT with me to keep in touch while in the Chattanooga area using the W4YI repeater and Kenny’s AllStar node.  And I want to thank Tracy KIØHC, Greg WB7AHO and Kenny K4KR for keeping me company on the ride and helping me with a couple of tech problems with the motorcycle I had on the trip.  Basically it seemed I lost my charging system and had to get a couple of jumps on the trip to Chattanooga, and I had to buy another battery and battery tender while visiting my Mom and friends but I made it back home just fine.  Really enjoyed the trip and catching up with friends and my family.  My Uncle gave me a really great Motorcycle rain suit that literally saved me on the way back with the severe thunderstorms and COLD RAIN back into Denver!

Dressed for bad WX on the motorcycle!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Loved taking the “state line” pictures!

 

The VERY FIRST radio station I worked at as a teen-ager!

The Vulcan at WFLI, Lookout MT, Chattanooga TN

 

 

 

 

 

 

 

 

Into Georgia, and a visit to Chickamauga Battlefield near Kenny in Chickamauga

 

Yeah about 2700 miles all said and done when I returned home. AND, now the charging system on the Vulcan is working again.  More on that later.  Note the HT holder on the right handlebar.  Not real sure if I will ever make such a long ride again, or at the very least not try to do 1350 miles in two days both directions.  12-14 hours a day on the bike was just too long.  Guess we will see!

Also, I had APRS KE0VH-5 beaconing for the trip and Rich NØEB tracked me and the statistics of my trip.  Now I was using a phone ap to do so as I hadn’t time to set up radio, but it worked just fine and served the purpose.  My wife, mom, uncle, Kenny, Tracy, and several other friends kept up with my progress as I motored across.  Thanks Rich for sending me these stats:

“There and Back Again” A motorcycle trip, not a Hobbit tale! KEØVH-5

By the way, one morning on the trip I went to have breakfast with Kenny K4KR!  Thanks for the great waffles breakfast buddy and the visit to the K4KR hamshack.  I of course had to see the K4KR AllStar Node 45649.  Kenny’s setup for his simplex node is really neat and clean and operates very well on his 2 meter simplex frequency.  Nicely done Kenny!

 

 

 

 

 

 

 

 

The K4KR AllStar node radio, power supply, and Raspberry PI3

 

Kennys AllStar audio interface between the radio and Raspberry PI3

 

 

 

 

 

 

And speaking of AllStar, I used my portable node from the hotel room I stayed in at Steamboat Springs.  The node utilizes my IPad connection to the internet and can be of course signed into a Wi-Fi from your hotel or home.  I also use my node at home by connecting into my wired network with the Raspberry PI3’s capabilities to do either.  Talking into the network with my Baofeng HT to the VX-170 node radio is easy and gets you on the air from wherever.  Thanks again to Skyler for helping me set this up.  If you missed the earlier article and descriptions of setting this up go to my archived 2017 August “KEØVH Hamshack article listed link below in this edition.

 

 

 

 

 

 

 

 

The portable KEØVH_AS2 (my second AllStar node)  portable AllStar kit box and Raspberry PI3

The IPad acting as the bridge to the internet plus the Terminus software to do different functions with the Wi-Fi connection to the PI.

We put in a new Bandpass/notch filter in our Steamboat Springs facility thanks to Steve (KI6FEO) at American Amplifier Technologies.    As I wrote about last year AAT supplied the bandpass filter for our Denver station and it has worked flawlessly!  So when we needed a new filter at 11000 feet in Steamboat we called Steve.  Proofing unfortunately will have to wait until next year due an early October snowfall of 24 inches at Steamboat.   Just didn’t make it in time this year.  AND, thanks to Steve as these filters he builds with AAT are really superior to anything I have seen before.  I will be requesting these filters exclusively from now on due to the workmanship put into each one of them and the performance.  Steve goes the extra mile (or hundred miles) essentially to build the filter to the specific needs of the station. This filter has a notch built into it to reject another close adjacent (in the same building) station.  Note the cooling fan on the top.  This is a high altitude site (11,000 feet AMSL) so you can get these with or without the cooling kit as needed.  Great stuff Steve and the folks at AAT!

 

 

 

 

 

 

The new bandpass filter in at Steamboat Springs, and KEØVH connecting it up!

 

 

 

 

 

We also installed a new bandpass/notch filter at our station in Colorado Springs and this time a receive filter since we are on the edge of reception for the station being repeated.  This is another site that we just obtained and moved the station essentially from a mountain top to a much better site down in the city to fill in a hole between our two 100 kw stations south of Colorado Springs and in Denver.  This site is also right on the southwest side of the city with mountains between the higher power sites so reception was tricky.

 

The new bandpass transmit and receive filters install at another site

 

When we put in this station the signal indicator on the BW receiver was reading in the 19-20 dbuV range.  This site is right under multiple 100 kW stations on Cheyenne Mountain in Colorado Springs.  Lots of RF to cause interference overload.  With close adjacent signals.  As you can see below, the signal basically doubled in strength, and multipath improved, really improving our repeated signal with the new receive filter.  AGAIN, great job American Amplifier Technologies.

IMPORTANT NOTE:  We have completed our transition to the ALLSTAR system, and we have with a better connection for those of you using ECHOLINK, which will stay in place, but simply move to another ECHOLINK NODE.

Henceforth, those of you coming in via ECHOLINK, please use Echolink node KD0WHB-L, or number 985839.

I will be keeping a link into 9615 IRLP for special use by those who only have an IRLP link capability at this time.  BUT it will not be the main link anymore due to problems it has been having cross connecting into ALLStar.

 

You will find that the audio coming thru the new ECHOLINK 985839 is much better than the other IRLP reflector too.

 

NOW, if you want to get on AllStar directly,

1st, see if there is already an AllStar repeater on the air near you.  Email me if you want help on this.

2nd, you can build your own portable AllStar node out of a RaspberryPi3 which of course is readily available.  Email me for more information on this.

 

3RD and most immediate, you can (you will have to register anyway), you can get on the AllStar Phone Portal via your cell phone very easy.

Go to https://allstarlink.org/ and sign up for an account.  Once you have that, (it usually takes about 24 hours to register) and you have an AllStar PIN, you can use the phone portal to get on the net.  Think of it as a long mic cable to connect your microphone (cell) to the system linked to a repeater (or several).  I can send you an auto dialing script once you have your PIN.  Makes it very easy, audio is great, simple to use and no more having to employ a laptop.

 

BTW, you can also get the Echolink APP for your phone and do the same thing if you don’t want to use AllStar.  As stated above, please start using the Echolink node 985839, or KD0WHB-L

The KE0VH Hamshack for September 2017

September 10, 2017
By

September 2017

Once again, my new email address is now ke0vh@outlook.com.  I have changed it due to some problems with access and my cell phone.  Please make a note of it!  J

The Monday Night SBE Chapter 73’ of the Air AllStar/Echolink NET is making the transition to the new connections very well.  We hope you will join us some Monday night in the future.  We are soon hopefully going to in addition to the WØGV 448.975 repeater adding the 449.625 WØKU repeater that we were on before.  We are planning on moving it to Mount Chief in Denver since KXKL FM (KOOL 105) vacated a space in the “basement” of the building.  It will also be connected to AllStar via facilities provided by Tracy, KIØHC.  More to come on this in the future.

Speaking of AllStar, Skyler, KDØWHB help me to put together my raspberry Pi3 portable node to carry on trips with me.  The node is easy to transport and sets up quickly in a hotel room.  I then can connect either via the Wifi to my IPad, or a network cable plugged into a system.  On my last trip to Steamboat Springs I used it to talk back to the Denver repeater and linked AllStar system.  I hope that many of you will look into connecting to us with one of these very transportable system.

 

More on the Raspberry Pi3.  See this article for how to use a Raspberry Pi as a ham radio TNC: https://tnc-x.com/TNCPi.htm

 

I hope you got to view the “Great American Eclipse” on August 21st.  I spent the days prior building a really easy “sun funnel” to put on my reflector telescope for safely viewing the event.  In Denver we expected a 92 % occlusion of the sun.  Glasses 2 weeks before the event were easy to find.  But the week before, they were nowhere to be found.  A pinhole projector of course would be usable, but I wanted a better look in magnification.  So after a search on the internet I found how I could build a funnel to attach to my 4.5 inch reflector telescope.  A trip to an auto parts store later I came back with a standard easily available oil funnel and some hose clamps.  Then after a visit to a local Walmart for a cheap shower curtain, I built this:

 

The Plossl eyepiece fitted into the smaller end and the bigger end of the funnel with the shower curtain (2 layers) “screen”.

 

My 4.5 inch Konusmotor 130 reflector, with sun aperture cover and the sun funnel showing the first aiming at the sun as the eclipse started

Here are some views taken with my cell camera of the eclipse as it progressed here.

Pretty amazing!  Our tree acted as a “pinhole” projector!

A closeup!  Pretty cool!

This is what the eclipse looked like from 72000 feet as seen from

The EOSS (Edge of Space Sciences) high altitude balloon flown from central Wyoming by the Colorado based group (www.eoss.org). See the entire video of the shadow moving across that part of the country at:

Good friend and “transmitter” whisperer J Steve Wilde, KI6FEO, took a trip out to help troubleshoot and find some issues we were having at a site here in Colorado.  Steve is an expert at tuning filters and getting things running in the best way possible.  He solved a couple of issues and did some fine tuning in our bandpass filter at this site.  Steve really has the touch when it comes to tuning high power filters and getting everything operating within parameters.  Steve, myself, and Rich W9BNO, worked for several hours on the transmitter, RF “plumbing”, the filter, and other issues and finally got the station running back at full power and stabilized.  We are hoping to make further improvements and doing more work at this site in the future.  THANKS STEVE and Rich!

Getting the parameters well within proper operating limits!  GREAT JOB STEVE!

 

As I have written in previous editions, I love it when you see ham radios used in TV shows and movies.  This month’s capture features a shot of detective Danny Williams (played by Scott Caan) using what looks like a Yaesu FT-60 in one episode.

With today’s laptops and computers serial ports are becoming a thing of the past and sometimes makes using some older ham gear interfaces a bit of a challenge.  You can always use a USB to Serial adapter to make the connections needed, but most of these will use something like “COM 10 or 11” to interface the software to the ham equipment being used.  Older software will sometimes only have COM 1-4 available in a pull down menu.  There is a way though in Windows to make happen what is needed in these cases.  Going into “Control Panel”, then to Device manager look for “Ports”.  Look there for the USB device that the computer has listed that you want to use.  Double click on that and then on “Port Settings”.  Another window should open then you will select “Advanced”.  You will get a dropdown that will allow you to look for another port number.  Selecting a Com number that matches your software requirements will solve the problem.  Virtual Com 11 becomes whatever Com you need.  GREAT TIP I read about on the internet!  This will help with many older serial devices used by ham operators to keep good stuff running (at least in the current versions of Windows.  I wish it were that easy in Linux!  J

By the way, another picture of the Eclipse taken by Sam, in Rocklin CA during the event.  I forgot to include it above.

 

Here is a beautiful mobile installation done by our friend Robert KC8GPD.  Robert also is helping us out as a contractor for sites here in CO.  He installed a Motorola Analog Spectra 70cm rig and a CB SR89MC radio in his Suzuki Grand Vitara.  He hopes to replace these radios soon with a Connect Systems CS800D (the dual band model)!  Stay tuned!

IMPORTANT NOTE:  We are going to make yet another move as we transition more to the ALLSTAR system, with a better connection for those of you using ECHOLINK, which will stay in place, but simply move to another ECHOLINK NODE.

 

Henceforth, those of you coming in via ECHOLINK, please use Echolink node KD0WHB-L, or number 985839.
