Re: OT:Tube Regenerative Receiver 12SN7/12V6

 

It sounds similar?to a regen by Newkirk in the September 1992 QST, also reprinted in the book QRP power. It does use two dual section tubes. I built it and it's a good performer.?

Awhile ago, when the regenrx yahoo group was active, I built several different iterations of regenerative receiver on the same small chassis.? It started as a twinplex, then changed to a 6SJ7 detector / 6SN7 dual audio amp, then the version it is now.? The problem is I can't remember or find the article it came from.? It uses a both sections of a 12SN7 as a regen detector/Audio preamp and the 12V6 as an audio amplifier.?? It has an audio output transformer but no interstage choke.? The original used 6 volt filaments but I used 12 so could power from the shack 13.8 PS.

Anyway, after pulling the radio off of the shelf, was listening for awhile.? It tunes about 7-10 Mhz and receives AM, Sideband, and CW pretty well.? Appreciate if someone can remind me of where got the article to build this one.? Or, point me to a group with folks building tube regenerative receivers.
