Hi Friend! Thanks for showing up. This is my second homemade radio page. The first is my homemade crystal set page. I got so excited about this homebrew project, I decided to make some tube sets too.

I would like to tell you a little about my background. My interest in radio goes back to around 1955 when I was 5 years old. My dad used to repair radios before I was around. Luckily he got into something that actually paid real money. Luckily too, he kept all the old radio stuff. I started soldering and fiddling when I was almost 10 years old. My dad had earned his Amateur Radio license, and I tagged along. I learned a lot.

For the next 25 years, I put together many projects, tube and semiconductor. I earned my Novice ham ticket in 1965. This only accelerated the building. I was a nerd before it was popular. I just sat in my cellar and played with my Weller as someone once said.

I built quite a few crystal radios, but never any regenerative radios. These pages will describe the regen sets that I am working on. I do these pages in near real-time. If I am waiting for parts to come on or the shellac to dry, I pop into the computer room and type a few lines of code.

I have no radios to show you right now. But here are my plans:

Build a two tube regen radio for the broadcast band using two 1T4 tubes.
Build a two tube regen radio using two type 30 tubes with plug in coils for broadcast and shortwave bands.
Build a regen radio using 12 volt hybrid tubes. These are tubes that only require a 12 volt plate supply. They were popular just before fully transistorized radios were made for autos.

So, please come back. It might take me a couple of months to have something worthwhile here as it is somewhat more difficult to find these parts.
