Hi I have built a regenerative receiver using this schematic http://ok1ike.c-a-v.com/soubory/tipy/001.gif
But it does not work.
If I connect a 10K from the base of the transistor (c3 pin) to the vcc, then I can listen to stations but the controls do not change neither the frequency or the regeneration. I can listen to all band stations at once, no selectivity.
Any ideas of what might be wrong, before I abandon the circuit and consider it as junk?
I like the fact that it uses pots instead of caps for the tuning and that it does not use tapped coils.
