Noisy Regen 2

[Aurel]

In process of construction based on many builders
like AlanY and some other guys...
At first i will try to build Short wave version where I will try
to cover large range - 3-30MHz
see ya...

AlanX says about this circuit:

Quote: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!

hmm I will see..
I already tried with old vintage 2N2326 and with ferit toroid
and i get nothing ..those transistors not work with 3V bat

I tried with 3V ( 1x1.5V battery ) and circuit not respond then
try to simulate oscillator in PintarVL & EWB.
I get results using current reg with emitter resistor of 820 ohm.

For conclusion this version of receiver work very bad or not
work.
