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?

Hygge DX
Just read about Scandinavian versions of untranslatable concepts (like German’s gemütlich or Portuguese’s saudade) at Quartz.
One example is the Danish word hygge (pronounced ‘hooga’)…
There’s no direct English translation for hygge, but the word evokes both coziness and togetherness. “It’s not just cozy with a blanket and a glass of wine,” Kurtz tells Quartz. “It’s also interpersonally cozy—so having a few people with you talking about issues and things you care deeply about. Having some candles lit, maybe a nice warm drink in your hand. Feeling safe and content.”
The Norwegian equivalent is koselig.
Psychologists working at the University of Tromsø have found that those further north in Norway have more positive wintertime mindsets. Kari Leibowitz wrote a piece for The Atlantic explaining how people flourished there during winter.
It all helps explain the popularity of Dxing and SWL as a group activity as written about here a while ago.
I just checked and four of these Norwegian radio friends spent another week or so over October and November DXing, and eating and drinking the best the planet has to offer enjoying their QRM-free QTH with views out over the Barents Sea! Analysis of their reception recordings continues over here.
That’s a sustained radio bliss!
My Favorite Contest

A few blogs back, I briefly touched upon my favorite contest of the year ... the 160m Stew Perry Contest, or more affectionately noted as the 'Stew' or 'SP'.
The contest is named in honor of W1BB, one of the earliest and most dedicated proponents of 160m in its earlier days, as well as being the first amateur to earn 160m DXCC #1, in 1976.

These bulletins were chalk-full of DX reports, station information, and antenna-building hints. It was hard not to get excited about the Topband after reading one of Stew's bulletins!
This was largely back in the day when very few commercial transmitters had a 160m position on the bandswitch. If it did, it was most likely a hernia-making DX-100 or a similar E.F. Johnson biggy ... seems most 160m ops were he-men back in the early days.
![]() |
| Heathkit DX-100 |
The 'Stew' is just a short 24 hour affair but often packs the CW band from end to end with a ton of activity, including lots of DX. It seems that most 160m diehards will jump at any opportunity to get on their favorite band, especially when conditions are as good as they have been of late.
The 'SP' is somewhat unique in that its system of scoring is probably the fairest of any contest around. The number of points earned for any QSO is determined by the distance between the two stations, with your computer contesting software dutifully making the needed calculations automatically from the exchange of Grid Square information, rather than the ubiquitous '599'.
Such a system gives stations in the western half of North America a chance to compete, on equal grounds, with the much higher activity levels found back east. With most contests awarding fixed points per QSO, it is much easier for eastern stations to rack-up big scores by working the multitude of other easterners ... this is just not possible out west where activity levels, and population densities, are so much smaller.
Contest PR-man ... Lew, W7EW, on behalf of the Boring (Oregon) Amateur Radio Club sponsorship, has sent a heads-up via the Topband reflector, which is reproduced below in case you wish to learn more.
Greetings Radio Ruffians with a TopBand Bent,
The anticipation is palpable as time draws near for the
start of the 21st Running of The Stew Perry TopBand DX
Challenge sponsored by the multitude of Amateurs who
make up The Boring Amateur Radio Club. The contest is Dec
17/18. That is this weekend coming up, for those of you
that need reminders like to remember an anniversary, put
gas in the vehicle or to breathe.
The rules for this contest are different. Please navigate to
http://www.kkn.net/stew/ and see how they are different.
Another unique aspect of The Stew is that The Boring
Amateur Radio Club does not specify categories to win
handsome plaques. You, the combatants do that. Yes,
anyone who thinks up a stellar category and remits $60 or
$63 to us will join the radio stalwarts listed below who are
stoking the fires of competition.
KL7RA Top # of QSOs by a S/O
N0TT Top Score, S/O, <21Y/O, > 200 QSOs
K7CA Longest DX, S/O, Low Power from Zone 3

Dr. Beldar-L1AR Top Score,S/O, Temporary Antenna erected > Dec.3
(All parts of temporary antenna including radials must be
installed after Dec. 3, 2016. This antenna must be the only antenna
for TopBand at the station and may be left erected because as we
all know "temporary" means "until I die")
KR2Q Golden Log Award

VE9AA Yr Trees Ants? If you have your TX wires in the trees or even
attached to 1 tree and your adjudicated score is closest one to
tree tree tree tree (3,333), then you win this plaque
VK6VZ VK6HD Memorial- Top Score by N. hemisphere station working S.
hemisphere stations.
Winner gets a new, fresh Flying Doctors of VK baseball hat
This list grows but will become even longer after you dream up a
contesting category. Just email me with the particulars so we may flesh it
out as some prior plaque proposals were too obtuse, couldn't be performed
by any one of our species or just a tad obscene.
There will be one or two more postings of the categories and sponsors
right up until and through the start of The Stew so don't delay! Also those
who haven't sent off their check or PayPals for their plaque sponsorship yet should not delay either.
Also follow Stalwart's VK6VZ's example and go fire up your system
tonight so you won't be modally morose when the only thing that happens
when you call CQ is that you open and close the neighbor's garage door
with a distinctive cadence.
73 and I remain,

If you have a few hours of free time this Saturday night, why not give the 'Stew' a look, especially if you've never operated on the Topband. If you can load-up that old longwire on 160, I'll guarantee you'll have fun as well as be surprised at what you can work ... hopefully I'll see many of you this weekend in the best contest of the year!

Simple Solution for a CW Paddle/Key Selector
I needed a switch, one that would allow me to select the key or paddle that I wanted to use. So I begin looking for a switch to suit my needs among ham equipment suppliers, but found nothing. I finally found a couple of schematics on the web to build my own and decided to take that path.
I was about to start ordering the parts when a friend of mine was visiting the shack. I told him about building the switch and his response was; "why do you want to that, you can a switch on EBay that will be relatively cheap and do the job". He told me I wasn't Googling with the right words. He suggested I try "3.5mm audio switch ". Who knew? Much to my surprise and delight several devices came up that would meet my needs. Here is the link to the one I bought.
http://www.ebay.com/itm/4-PORT-3-5mm-STEREO-Manual-Sharing-Switch-AUX-Audio-Speaker-selector-way-4-1-/290812907832?hash=item43b5ccd138:g:MpMAAOxyn~pRz8yb
A cable with an 1/8" on one end (switchbox) and a 1/4" connector on the other, (K3 plug) works for the K3. Simply connect the switch via the cable to the radio and then plug in your keys, paddle, etc. into the switch. As can be seen below I have a straight key, bug and Winkeyer plugged into the switch, while the paddle is plugged directly into the radio. I actually have an empty port in the switch where I usually have a second bug plugged in. You could actually get a second switch that would allow multiple paddles to be at your disposal as well.
So when I'm chatting with my CW buddies I can change my method of sending code with the push of a button. I can answer a CQ'er with a like kind instrument. An operator calling CQ with a bug, I can answer with a bug, etc.. This switching solution is very easy and very economical. There are 8 position switches available as well.
