Down the Rabbit Hole
The Ten Tec Triton I/II transceivers were released in the mid-1970’s and marked a milestone in High Frequency (HF) radios. With coverage for the 80, 40, 20, 15 and 10-meter amateur radio bands, 50 to 100 watt output on SSB and CW, they may have been the first affordable, fully solid-state models.
As I mentioned in an earlier post, I owned a Ten Tec Triton IV (model 544) in the late 70’s and always loved it. I traded the radio a few years later for an ICOM 720a (also a great radio), but always regretted losing the Triton. Fast forward about 40 years, and the gift of an old Triton II reminded of that first love. The Triton II is similar, but the IV had several refinements that made it really great at the time, and I decided to get one again.
eBay has provided a lot of entertainment (and used equipment!) over the last few months, and after the purchase and restoration of a Ten Tec Century 21, I started looking for a Triton IV. This was the first radio I purchased new in 1978. I really enjoyed it and wanted to own one again. It didn’t take long. I ended up having two in the shop at almost the same time — one for my shack, and one for a fellow ham.
With the Ten Tec Argonaut 509 restored and working well, it was time to try it out. The Anderson Power Pole made it easy to connect an 8 amp hour gel cell. I hooked it up to my end-fed half-wave antenna and listened around 20 meters. There were plenty of CW signals and I quickly realized a CW filter was going to be needed.
In part one of this restoration, we tackled the Ten Tec Omni C’s two most glaring problems: garbled signals on receive and blowing fuses when the radio was switched to the 30-Meter band. I could now receive and transmit signals in almost all the band switch positions, albeit with varying sensitivity and power output. It had been quite a chase so far, and the remaining repairs would prove equally challenging.
