The KE0VH Hamshack for April

April 23, 2018

April 2018

Still keeping on with the Society of Broadcast Engineers Monday Night Chapter 73’ of the AIR VHF/UHF Hamnet.  Details on how to join us at the bottom of the article here.  Sure would like to have you join us from ANYWHERE in the world!

 

So with lots of flying flight simulator and drones for both EMF and for fun there hasn’t been a lot of ham radio activity for me the past couple of months.  Talking with my great friend Cris W5WCA on the 449.450 repeater most mornings here in Denver (mostly about flying!) and the Monday night net, plus checking into the Columbine Statewide Net on 3.989 MHz 7:30 MTN time has been most of my ham radio operations lately.  Earlier in the month of March my good friend Tim KAØAAI stopped by and we did some setup on his DMR handheld, and I have been talking some on the WØTX Local DMR machine with Kenny K4KR in the Chattanooga Tennessee area a bit.  Plus we are still on the ALLSTAR network usually connected into the KDØWHB Skyhub (node 46079) and on the WØGV AllStar repeater locally here in Denver.  The WØKU 449.625 repeater can also connect into the AllStar network via IRLP.  Pretty versatile stuff and we hope to expand the capabilities of all soon.  Stay tuned!
As mentioned flying both my company issued drone for work and my personal Phantom 3 Advanced for practice and fun has been a source of real enjoyment for me.  Getting to fly up and around towers in my zone are going to be quite informative and money saving for our company.  It gets you up and close to the antennas on the towers of course without having to have a tower crew and the expense.   This past month I put up a video on my “ke0vhjacktv” YouTube channel flying one of our sites.  It was a bit of a windy day and I got QUITE close to the antenna and guy wires on the tower.  WHEW! But I kept a close watch and am learning how to fly the drone (a Phantom 3 PRO) to get some great footage and detail on the upper reaches of the structure.  If you didn’t already take a look at: https://www.youtube.com/watch?v=B7v2ceKfqyY

Due to the current rules of flying near airports with controlled airspace you must now use a system that can take up to 90 days or so to get FAA permission if your tower is located within that space.  I have a tower that is in just that position that I really need to do an inspection at.  SO, at this time I have applied for the permission to do so but am waiting, and so I expect that it will be May before I get the OK to do so.  Details on how to apply are at: https://www.faa.gov/uas/request_waiver/  This web site shows a list of waivers granted, so I keep a look on it for mine to come thru: https://www.faa.gov/uas/request_waiver/waivers_granted/

 

However the FAA is beginning a program to make this process almost instantaneous.  That will certainly make things quicker and easier especially when you need to inspect a tower in controlled airspace quickly.  Take a look here:

http://aopa.org/news-and-media/all-news/2018/march/08/faa-expands-drone-authorization-program?utm_source=drone&utm_medium=email&utm_campaign=180320drone

 

The FAA UAS data delivery system website is absolutely outstanding at showing permitted flight levels and areas of the whole country.  This includes an amazing map that is movable and you can zoom into the area you are interested in.  Take a look at it at: http://uas-faa.opendata.arcgis.com/

 

Another discussion says Part 107 operations do not require that you contact nearby airports in Class G airspace.  That is a Section 336 (recreational) requirement.  Please follow up with any further inquiries at UASHelp@faa.gov.  Additional information is also available at https://www.faa.gov/uas/.  Please select:  UAS Safety and Integration Division AUS-400.

I am having a great time with my Flight Simulator setup in the hamshack.  I now have 3 monitors so it is very easy to simulate the “cockpit” with this setup.  It gives you a really 3D feel with depth perception, with a peripheral vision feel. I bring the monitors in so that they are together in what I call Flight Sim Configuration.

The computer screen on the left is switchable between the sim computer and my Win 10 machine so I can look up other airport and flight info.

As you can see the ham radio shelf is behind the center 32 inch monitor and inaccessible when I want to operate ham radio in this config.  So I took a wall mount and set it up in a vertical way so the monitor will hinge up and rest on the shelf.  That then makes the radios accessible and is in “ham station” mode!

This picture shows me “flying” the Beach Baron over our building in the Denver area!

With the Megascenery Colorado Flight Sim software flying over the state is really accurate and almost like using Google Earth!    Pretty cool!

Right under the trailing edge of the wing is our transmitter site buildings near Denver!

This is flying SW of Pueblo Colorado over towards Greenhorn MT near our Rye Colorado site.  WISH I could really get there this quick!  J

One weekend in March we had what the natives refer to as “Thundersnow” in Denver.  Sure enough, lightning struck near our Denver transmitter site and took out the ham radio connection to the 449.625 repeater up there AND our Nanobridge studio to transmitter backup link to our Trango main STL system.  Not a good thing.  Funny thing is the studio Nano was communicating with the unit on the mountain but the transmitter side wouldn’t pass any network data.  Checked the cable to the transmitter building and it was fine.  So, to make a several day ordeal short the transmitter site Nanobridge was taking power from the building but passing NO traffic.  Brought it down to the studio workbench and sure enough the network card was working from one side but not the other.  SO, we switched out the whole Nanobridge M5 system (no longer made by the way) for the Ubiquiti PowerBeam 5AC 300 system.  I won’t list here all that it is capable of doing, but it is really outstanding in 2 ways that I will tell you about here.  The first is if you need to change frequency to a different part of the 5 gig spectrum (5730 to 5840 MHz) you can tell the end you are working with to change and it will CHANGE THE OTHER END FIRST, then lock up both units together!  OUTSTANDING!  It has an onboard software alignment tool, speed testing, discovery mode, and a spectrum analyzer called “Airview”.  VERY updated from the old Nanobridge system.  BTW, the price is only right around $100 per unit.  The GUI has immediate real time monitoring of all parameters, signal strength on both ends, isolated capacity and throughput, signal to noise and interference, data rates of both ends, etc.  This was one of the easiest to aim and get working projects I have ever done.  Cris W5WCA helped me with the initial bench setup, Robert KC8GPD and Shane KØSDT helped with the studio and transmitter site setup.  Robert and I ran a brand new cable and lightning protector up at the transmitter and then I “sight” aimed both ends and we walked it in for maximum signal from both sides.  All tested well and I look at it just about every day.  Should our Trango system fail it is ready to go.  And soon, when our April pledge drives are over, we will put the PowerBeam on the air so we can do some needed work to the Trango system feed.  More about that in a later edition!

Transmitter site PowerBeam

STUDIO SITE UNIT WITH LIGHTNING PROTECTOR

A picture of the GUI for the Transmitter site end

 

And the studio site end.  As you can see the noise floor is higher at the transmitter end as might be expected.  We put a bunch of Ferrites on the network leads up at the dish to reduce the noise floor from -92 to -98, improving the Interference + Noise from a -79 or 80 level to -88.  Of course with a high power FM and UHF TV station less than 100 feet away this is outstanding performance almost as good as the parameters at the studio end.  I am really impressed with these units and recommend them.  Thanks to Cris for the original heads up about the Nano bridges and now the POWERBEAMS!  And since we ran our network link and HD2 audio for the better part of a year using these prior to the install of the licensed Trango system I am confident that they will do the trick!

The KE0VH Hamshack for March 2018

March 8, 2018

From my great friend and fellow EMF Engineer Shane Toven KØSDT, he leads off the March edition with this:

Item 1: Portable Allstar node using a 7” LCD touchscreen (and matching case) for the Raspberry Pi along with a small wireless keypad for control. This setup allows manual operation without a node radio using a standard USB audio interface and headset. The display and keypad are also handy for troubleshooting. The Pi, case, LCD, headset, and audio interface were all sourced locally from MicroCenter. I used the latest Allstar node image for the Raspberry Pi posted at hamvoip.org, which made it really easy to get started. Oddly, the display needed to be flipped 180 degrees. The appropriate Linux magic was simply adding the line lcd_rotate=2 to /boot/config.txt.

I also purchased a USB Radio Interface (URI) from DMK Engineering (http://www.dmkeng.com/Products.htm) and plan to press one of my handhelds into service as a node radio. The next challenge will be finding a good way to power it from my truck in a mobile environment without introducing electrical noise. At some point in the future I will look at ways to permanently integrate a node into my truck.

Item 2: Super simple APRS tracker using a Raspberry Pi, GPS “hat”, and Baofeng handheld. This project is a fun one and requires minimal work—no special TNC and radio cable or modifications required! The Baofeng is set with both VFOs tuned to 144.390 and VOX enabled. A simple 3.5mm audio cable is connected from the headphone jack on the Pi to the microphone connector on the Baofeng. Once the GPS is locked, the Pi begins playing properly formatted APRS beacon packets from its headphone jack, which triggers VOX on the Baofeng for transmission! Is it perfect? No—but it works surprisingly well! I used the “Ultimate GPS Pi HAT” from Adafruit, but any GPS (USB or serial) which will output NMEA compatible data should work just fine. This makes for a very compact all-in-one solution (just add radio). Since this particular GPS uses the Pi’s onboard serial port (which is initially configured for terminal access) it required a few small tweaks to disable that feature, but I’ve found it to be rock solid. An onboard battery maintains the last known position and real-time clock to avoid the full 30 minute “cold start” acquisition. There is a connector for an external antenna, but I have found the internal “patch” antenna to be more than sufficient in most cases. That said, you may want to attach an external antenna or place the unit outdoors in a clear area to obtain the initial fix. A bright red LED on the board clearly indicates the status of position fix. As a bonus, breadboard space is provided for additional modifications and experimentation. While there isn’t a pre-built “image” for this setup (yet) most of my information was drawn from here:

Information on the Adafruit “Ultimate GPS Pi HAT” can be found here:

Ultimate GPS Pi HAT

Lately Kenny K4KR and I have been talking a lot on the DMR Brandmeister link from the Chattanooga Tennessee area to the WØTX Brandmeister DMR repeater locally here in the Denver area.  It is a great system when you are in good range of the repeater, but digitally glitches or is not there at all if you don’t have a good signal into it.  The digital audio when the signal is strong though is really amazing.

From Harold, W6IWI who lives just a little north of me, he and I both experience high levels of noise making 40 meters and 75/80 very hard if not impossible to hear stations on HF.  I encourage you to check out his information and links on his website: http://www.hallikainen.org/org/w6iwi/   And here is a direct link to the form from the ARRL on reporting noise and getting it mitigated.  https://fs26.formsite.com/mbdHCx/form2/index.html?

Setting up my 3.5 inch screen on my Pi3

Another project for the month was setting up a display for the Raspberry Pi 3, which in the next evolution I will use on my portable AllStar Node instead of having to use a program called Terminus on my IPad to communicate and control the node.  There is a great video on YouTube that I used to install the program on the Pi and get it running.  I will work on the next version soon.  In the instructions in the video I had to change one line from his instructions and you will see where this is if you go thru the setup.  That line is: “sudo bash LCD35-show”.  You will see where this is and if you have any questions let me know.

KØSDT

The Pira CZ P275  FM Modulation analyzer

 

This portable Modulation analyzer does a great many things including RDS monitoring and that is very handy to have in such a small package.  In analyzes all aspects of the modulation of a FM radio signal.  Read about its capabilities here at: http://pira.cz/shop/  This company also manufactures RDS Encoders.  There is free software such as our guy in Rocklin, Dave is looking at in the picture below that’s really extends the versatility of these units.  I actually own an older model and use it to look at our signals when I am at one of my sites.  These are re-motable as well via serial USB, and can be set with alarms to let you know when an issue crops up if you leave one setup at a site.  The price is really reasonable as well, and the only drawback though is you have to order them from Czechoslovakia and it takes about 3 months to get here, and so if would follow that any tech support would be an issue.   I certainly hope that maybe they become more available to the US market thru local distribution.

Cris Alexander W4WCA Flight Simulator setup

As I included in last month’s article I have been “flying” a lot and learning how to navigate and use ILS to land aircraft in Flight Simulator X.  With getting into flying drones and getting my part 107 certificate to commercially fly them I really want to learn all I can about piloting AND have fun.  I even had the chance to go flying with Cris Alexander W5WCA in a Piper Cherokee Arrow III one day as he took us on a flight from Centennial airport in south Denver out to the south east to the little town of Limon’s airport, did a touch and go, then flew back to Centennial.  It was great to see Cris in action (a video will be coming soon) and fly with him.  I have been flying from (in FSX) all over the country with a 737-800 as seen in my previous video’s (see them on YouTube at KE0VHJackTV) landing so far in Kansas City, St. Louis, and Nashville as of this writing.  Flight dynamics, weather, air traffic control, all are very realistic and you can download scenery that really looks great and like the area you are interested in.

Cris with the Piper Arrow III we flew in at Centennial Airport

Cris and I talk just about every weekday on the 449.450 repeater locally here in Denver and just about all we talk about anymore is flying.

Using FSX Software, watch what a Southwest pilot would do during pre-flight and pushback from the gate then a whole flight from San Diego to Phoenix.  This is really interesting!

https://www.youtube.com/watch?v=L8j09rUsQzk

One of the cool things about the Microsoft Flight Simulators is the ability to get online and fly with other people, both those that fly and those that want to be air traffic controllers and the whole bit.  So one night Jeremy N6JER, (“norcalengineer” Flight Sim screen name) and I joined up on the FSX servers and “flew” together over southern California.  In the picture below Jeremy is flying his Beech Baron over the LA area on the way to KSNA (John Wayne) airport & I am flying the aircraft of his right wing at 2 o’clock labeled “KE0VH” of course!

I am still learning how to take pictures in the Steam version of FSX, so the below are just with my IPhone camera pointed at the monitor.

I am flying the plane in the foreground in this shot, Jeremy at 4 o’clock off my right wing.

This one is out my right passenger window, seeing Jeremy’s plane!  OK, I am HOOKED on this. 

As far as being a real pilot like Cris, this is as close as I will probably ever get, unless when flying sometime the pilot becomes incapacitated, and they yell “is there anyone who can fly the plane”?  Well, even then I am not so sure, but at least I will understand it.  LOL!!!!!!!!!!!!!!  Hey I can regularly routinely land my FSX 737-800 so…..

Speaking of flying though, at least I AM a FCC Certified UAS Pilot!  So I can call myself one anyway!  Here are some pics from flying the Phantom 3 at one of our sites last month!  It was a very windy day, so it was good practice as well as getting some pictures I needed.  The tower was about 330 feet or so AGL, and it allowed me to really test my current skills and learn how the drone behaved.  My handheld anemometer said that the wind was in the 20-25 MPH range, the drones top speed is in the 35 MPH range, so it was able to hold its own in the wind, but the tilt at which it was operating was pronounced but these DJI machines are really able to hold position well in the wind.  They are satellite and GPS navigated so they are really very smart and stable camera platforms to be able to take the look at our towers and antenna’s without having to risk a tower crew.  Below is a drone “selfie”!

 

The view of the whole site looking NE from the Phantom at about 250 feet!

And at 350 feet, the top of the tower.  Notice the drone arm upper right.  The Phantom here was tilted into the wind holding position.  It wasn’t moving in this picture!

BTW, my buddy Lee NØVRD sent this picture to me of a lamp created out of tower side lamps.  Great idea, wonder if wives would think it matches a room……… Well great idea anyway!

As a top 40 jock from way back, (glad I got that out of my system!) I LOVED using Cart machines.  See this great article in RadioWorld about how the cart machine made the Top 40 format possible at:

https://www.radioworld.com/tech-and-gear/be-cart-machines-the-first-and-the-last

AND YES, something HAM RADIO!  Have you tried using the WebSDR yet?  This on web HF receiver can really help you to hear some stations that you might just have in the noise at home.  Really awesome tech!  Check it out and listen in maybe even to your own signal at: http://websdr.org/

The KE0VH Hamshack for February 2018

March 8, 2018
By

 

 

 

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.

https://www.youtube.com/watch?v=FV8PMwbGh08

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

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

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 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.

The KE0VH Hamshack for December 2017

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!

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!

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!

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:
