The Spectrum Monitor — December, 2016

Stories you’ll find in our December, 2016 issue:

The Coast Guard Cutter Courier: “A Cold War-era Battleship without Guns”
By John Schneider W9FGH

The Voice of America operated a unique shipboard radio broadcasting facility on the medium wave and shortwave bands in the Mediterranean Sea from 1952 to 1964. The US Coast Guard Cutter Courier was a seagoing Cold War shipboard broadcaster, which preceded the famous pirate radio ships of the 1960s and 70s and was the home to the most powerful transmitter ever operated aboard a ship. But, it was not always smooth sailing. There were complications with the 900-foot balloon-tethered medium wave antenna and constant jamming from Russian-based transmitters.

Experiences of a (Relatively) Young Ham with Vintage Radios
By W. Eric McFadden WD8RIF

While the author has been a licensed ham for 38 years, he’s relatively young. And, since most of his operating gear is modern, he’s fairly new to vintage radio. He writes that he wanted to experience what the hobby was like for earlier generations and he felt the contagion of many of his close amateur radio friends who are quite into vacuum tube-era gear. He’s apparently a quick study because now he has some good-looking vintage gear in his shack, including a Heathkit HW-16 and a Drake 2-NT transmitter and 2-C receiver as well as tube-fired 6-meter gear. He’s definitely hooked!

Beware the Mods: Drake 2NT Transmitter
By Rich Post KB8TAD

Longtime vintage radio guru, Rich Post KB8TAD, helps Eric McFadden restore his Drake 2-NT transmitter and shows the rest of us some of the things he does to give vintage radio gear new life. Here’s a hint: It’s not easy and it helps to have good diagnostic equipment, skills to operate that equipment and many decades of understanding the variables of tube-technology.

Shortwave Listening with the “Old-Timers”
By Eric Beheim

Growing up in the 1950s and listening to his grandfather’s 1936 23-tube Scott All-Wave console shortwave radio was a pretty good start for young Eric Beheim. That’s why today, Eric likes to listen to the shortwave bands on number of vintage shortwave radios, including a 1936 Hallicrafters S-20R Sky Champion and a 1942 Zenith model 7G605 Transoceanic “Clipper” among others. Listening is not as easy as you might think. Eric writes, “Most older radios lack the sensitivity, selectivity, and stability that we take for granted in our modern sets. But that’s what makes monitoring with the ‘old timers’ both challenging and exciting.”

A Salute to the Esteemed Regenerative Receiver
By Richard Fisher KI6SN

Fifty years ago, a teenage Richard Fisher, sporting his Novice call, WN1DWL, found he was at loose ends during his high school winter break. What better way to pass the time than to build a regenerative receiver that he could use to cover the ham bands from 160 through 10 meters? It was a project financially within reach of “a broke 16 year-old.” Years later, while he still had the rig, it had fallen victim to the ravages of time and “parts scrounging.” Now, Richard thought, what better way to celebrate the 50th anniversary of that little radio than to restore it to its full regenerative glory?

For the most part, AM is used on most of the channels but you’ll find LSB activity on Channel 36 (27.365 MHz). And when the band gets busy and crowded, you’ll hear LSB QSOs from Channels 36 – 39 (27.365 – 27.395 MHz).

Hams on Strava

Count me amongst those who consider DXpeditioning and radiosport contesting true sports on par with chess, professional poker, America’s Cup sailing, and similar pursuits. Operating SO2R for 48 hours straight in CQ WW, chasing WRTC qualification, and pounding out 160m Qs all night from sub-Antarctic Islands are not for the faint of heart, literally!

No surprise, then, that many DXers and Contesters also participate in endurance sports such as running, cycling, and triathlon when not on the radio. The ‘king’ contester/endurance athlete must be Thomas OZ1AA who spent five years cycling around the world and operated contests from whatever country he happened to be riding through along the way. Thomas’ amazing Cycling The Globe Blog is here:

http://www.cyclingtheglobe.com/

Thomas logged his cycling travels on Strava, a smartphone app that uses GPS to track cycling, running, and other sports, with share/compare social media functionality. Think of Strava as Logbook of the World for cycling and running. Thomas’ Strava feed is here:

https://www.strava.com/athletes/7378076?oq=thomas

Are there other hams on Strava? Yes! At Force 12, yours truly (AA7XT, triathlon) and Jon (KL2A, running) are both active Strava users:

https://www.strava.com/athletes/2467

https://www.strava.com/athletes/15413914

If you look at the Strava users that Jon and I follow, you’ll see many DXers and contesters including Juan TG9AJR, Mark N5OT, Jeff N5TJ (CQ WW World Record Holder and an accomplished bicycle racer), and many more. There are also numerous ham oriented Strava Groups. I’m a member of  the “DXCC” and “DX Runners” groups.

If you’re on Strava or are going to sign up (it’s free!), please do connect with Jon and myself. Maybe we can have a meetup at Dayton and go for a morning group run? Or create a combo annual contest points + mileage Strava Challenge?

I should note that Force 12 engineer/builder Jeremy KE0CGU is the best athlete at the company but does not use Strava (Jeremy prefers his time outside to be away from gadgets – purist!). Jeremy commutes to F12 via bike regardless of the weather and also has competed in mountain ultra-running and long distance mountain bike events.

Please Thank a Vet

A few day after Veterans Day, I am still awash in the recognition vets received on their special day. In the interest of full disclosure, I spent two years on active duty and four years in the Army Signal Corps Reserve during the Korean War era, which probably doesn’t make me an impartial observer.

In actuality, this story began about ten years ago. I was visiting relatives in Florida and was dispatched to the supermarket to procure a few last-minute items. As I was walking into the store a distinguished looking old timer was heading toward a car with Purple Heart courtesy license plates. (The Purple Heart is presented to United State military personnel who have been wounded in combat.) I walked over to him and put out my hand and said, “thank you for your service and sacrifice, I sincerely appreciate both.” Whereupon he started to cry and said, “I’ve had these plates for ten years and you’re the first person who has every said a word!” In the discussion that followed, he told me he was a Marine who received a serious leg wound while fighting on Iwo Jima. Sixty years later he still walked with a serious limp. He also received the Bronze Star for valor in action. My new-found friend dispatched me with a big hug and an emotional, “thank you.” This chance encounter made my vacation and literally changed my life.

Over the ensuing years, I’ve frequently thought about this WWII hero. I wish I had taken his name and address so I could have remained in contact. It has also reminded me of the vast number of vets who gave their life or years of their life in the service of our country. You may be totally anti-war but in my opinion, even the most avid pacifists owe homage to those who died or were willing to serve to give them the right to protest.

Looking for vets I would simply say, “thank you for your service” and shake their hand if the occasion presented itself. I am especially on the lookout for Viet Nam vets as they were the object of disdain when they came home. People would spit at them and called all types of names. Possible a few acts of kindness now can help erase the pain of their homecoming. When encountering a WWII vet, there aren’t many left, I try and engage them in conversation. If I’m in the check-out line at a convenience store and there is a vet behind me with a container of coffee, I frequently tell the person at the cash register, “take out for the vet’s coffee.”

Don’t be surprised if thanking a vet, or other random acts of kindness, makes you feel better. Knowing you have brought a smile and a good feeling to another human being is a very special thing.
