Triton and Me: Back together Again

Figure 1The Ten Tec 540 is playing love songs again

Four times I courted her.  Three times I dropped her.  This time it’s forever.  Over the years, I’d managed to find myself paired with the one whose songs were so delightful, whose voice stuck in my memory for the whole day long.

Impressionable and easily infatuated, my young mind learned of the CW siren, that seductress of the airwaves.  Long into the night, I listened to her soft messages, sometimes drifting off to sleep with my hand on the key, eventually slipping into one of those sweet dreams of hamdom.

Junk or Joy? Heathkit GR-78 Amateur / Shortwave

Figure 1:  The venerable? Heathkit GR-78 receiver, as it was found in flea market.  

What ham can resist the allure of a piece of vintage gear, sans cover, knob, and a part or three, looking ever like the cartoon character with sprigs of pointy hair wires protruding from it, and connected to nothing?  When we go to ham swap ‘n shops, we brace ourselves ahead of time, lest we not load our trunks with the contents of theirs.  We have time in such cases to revisit the vision of our junk corners at home, and the XYL’s displeasure of same.

But …

Unboxing a Forty One year old Ham Radio

Figure 1: Unboxing another Alda 103

Another Alda?  I’ll admit to having an affinity for them.  The one I already have is the 80-40-15 tribander (the 103A) – and the one I’m unboxing is the 80-40-20 tribander (the 103).  The package came in a solid little Home Depot box, and no shaking or rattling could be heard during a shake-test next to my ear.  The question on my mind?  Would I hear more from the speaker of the actual 103 when I finished opening the package and plugging the little gem-from-the-past into my supply?

Ham Radio on a Pi2

Some of the other posts on this site refer to my “homemade” tablet, which I subsequently outfitted with components for ham radio usage.  I recently built another “homemade” tablet, this time using a Raspberry Pi2 board for the computing power.

New (For Me) Omni-A (Analog)


I have always been a Ten Tec fan. As a kid I dreamed about the PM-1, but had to settle for home brew and (eventually) an old (even then) DX-40 transmitter / Lafayette-HA350 RX combo. When I was older, I purchased a Triton 4, and fell in love with the quietness of its noise blanker assisted audio, its filters, and its fabulous QSK. Some time ago, I decided to find another Triton (I’ve had and subsequently sold several, when I wish I’d kept them all!) The prices have crept up, as the numbers dwindle, and Ebay resellers have ascertained that hams will give blood for these units. They are made primarily of discrete transistors, with a smattering of commodity ICs, and so are relatively easy to fix in a pinch.
