Very smooth regen control. Except for the plug-in coils requirement...

Though I realize the feedback windings would be problematic to reproduce...I
listened to many 40M SSB QSOs on Saturday mornings with the Knight Space
Spanner.


Perhaps LA5KI would consent to doing some measurements on his coils...

It is called a Super-regen here, but I don't think it was.

Hi Group, I am entertaining building anohter regen. My first attempt,
although pretty, was a mediocre performer- using a 3 section compactron
tube.

Design goals a
1. plug in coils for band changing MW-20 MHz or so.
2. speaker level audio
3. smooth regen
4. prefer miniature tubes to octal.

Anyone care to post their favorite schematic/ links/ thoughts?

Tnx,

I compose in Word then paste. This part didn't get pasted:

I had the Knight-Kit Space Spanner and used to listen to some SSB regulars
on 40 M every Saturday.
