[Boatanchors] regeneration and selectivity

[Radios R. Me]

Very good Henry - 

That sounds like you pretty much turned that i.f. stage into a 
very basic Q multiplier. Good idea. If it worked, why not!

Subject: [Boatanchors] regeneration and selectivity

I brought up this idea a couple of years ago on one of the WS19 reflectors. About 30 years ago I added adjustable regeneration in the (first?) IF stage of a TCS and a Bendix RB-(?) aircraft receiver by running a high resistance rheostat between the grid and plate in series with a blocking cap.
It was very effective in both receivers, resulting in Q multiplier-like selectivty.
