Regen Radio Ideas Needed

Just keep in mind that you may be disappointed at the audio level from this. Part of the reason for this is the fact that most modern headphones are designed for good fidelity over high sensitivity. If lack of volume turns out to be a problem, just add an audio stage (another #30 would do nicely).

things!

Thanks, how would I add this audio stage? A diagram would help.

Search for Doerle Regen, that was a popular 2-tube regen typically using #30 tubes. Here's one diagram I found:

Hi Michael

Thanks for the lovely explanation - well for a beginning project i was so excited I could hear ATC in my local area - I am in the process of building another one for my brother so he too can listen to ATC.

With the super-regen - as the voltage drops from the source, will the resonant frequency begin to shift?

Say if it goes from 10 to 8 volts. I am using a MPF102. Regards

Shelton.
