Here are some photos of the Ozark Patrol Regenerative Receiver kit that I put together. The kit is well thought out and uses a PCB as the front of the radio. The build time is about 6 hours total.

The kit uses through-hole parts, but a surface mount PCB in what is known as Pittsburgh construction. The leads are bent into a W shape and soldered to pads.

The hardest part of the kit is winding s 20 turn coil. So this is a really good kit for the novice builder.

I had never tried a regen radio before. It is really easy to overload the receiver with an antenna so a tiny value "gimmick" capacitor made from twisting wire is used to couple them together. It was neat to learn about that.


I liked this enough that I want to try a simple tube regen receiver next, like this 12V 12AU7 regen radio

What a beaut! :D :D :D

Brings back fond memories, for sure.

It sounds like the Ozark Patrol kit is fashioned/inspired after the Radio Shack Globe Patrol regen radios. I remember looking at the Globe Patrol as a kid, but I was far more interested in crystal sets and SW receivers so a regen receiver had managed to elude me until now! As a kid I would listen to night time late night (west coast) baseball games broadcast out of ND when I was supposed to be sleeping.

Instead of using a "gimmick" capacitor as suggested in the manual I would suggest using small value capacitors to couple the antenna. Using a few 18pF ceramic disc capacitors values of 9, 18, 36 and 54 pF worked well with a 10 m wire. I suggest using fixed values over the gimmick as with the known capacitance values it is much easier to fine tune performance. A variable cap could be used here too.

Anyway, this kit sure has stirred up the radio bug in me.
