How to Build a Great CW Filter for the Ten Tec Triton IV

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.

I’ve been a Ham for over 45 years, but have never really gotten comfortable with Morse Code. Sure, I was able to pass the code requirement when I first got my Technician and later Advanced License, but my CW chops were always shaky at best. I had been more interested in building and modifying equipment anyway, so it didn’t seem like a major deficit.

It’s been nearly two years since a pair of classic old shortwave receivers followed me home from California, and they have been staring at me each time I enter the shop ever since. Neither are functional, and both are daunting restoration projects. I wanted to revive some of my old vacuum tube chops and collect some vintage test equipment before diving into these beauties.
