Subject: Re: LF: 136kHz Getting started.

I'm not much of a designer so basically MAR-6 with 100R  from 5v supply 
and 47nf caps for i/o coupling, the parallel tuned input just a  ferrite

wound inductor (from a old TV board)  and some caps to bring into 
resonance on 136, it's not very high Q but it works to keep the 
broadcast breakthrough out!

Nothing that complicated ... i like it to be simple!
