Noisy Regen Test

Well I assembled and tested the noisy regen today:

Performance wise with the short antenna it was a little better than the first one. With a long antenna not as good. Selectivity was better (likely due to the higher input impedance as a result of lower collector currents).

Exciting? No. The reflex circuit was much better (but then I used a proper coil). Would I recommend it? No. Is it all the coil problem? No, I don't think so. To get an idea about how bad this receiver is, without the high gain audio amplifier you would not hear anything. I suspect a Ge diode followed by the same audio amplifier would work better!

Here is the layout:
