[Boatanchors] Regenerative IF

[Bill and Liz]

I have a homebrew receiver in the shop with a funny problem.  It has a regenerative IF stage and if you accidentally run up the regen control too far it breaks into oscillation and won’t come out for several minutes.  The whole receiver is “paralyzed”-there is no reception at all; very slowly it begins to recover, a process which takes another few minutes.

Anyone suggest what is happening and possibly how I can stop it from happening?  I have no experience with regenerative receivers.  Other regen receivers I have played with will go into oscillation but will come out quickly as soon as you back off the control below oscillation point.
