Another topic about the same topic. It is best to continue an existing topic instead of starting a new one each time.
I found your last one where Rick Andersen says about his super-regen design, "Another drawback is that the interaction between the main VHF frequency with the 25 KHz quench oscillation causes lots of "hash" -- broadband noise with many minor points on the dial where the audio can be heard; tuning though this can sound like a "fluttering" and it is sometimes difficult to find the exact center of tuning."
I think the quench frequency is affected by the RF input's signal strength.
but the values for the quench frequency are chosen for a reason. It seems in my circuit I currently have a quench frequency of 250Khz, which will be changed. I can't see the input signal electrically changing the quench frequency, but I can see one changing the quench frequency so that it is optimized to match the input signal.
I am still looking for the optimal frequency.
My incoming frequency target is between 100 and 200Mhz.
You don't want the hash points on the dial caused by the quench frequency to be spaced exactly the same as the 200kHz channel spacing on North American FM stations nor whatever the channel spacing is for the aircraft band.
