FM for the Bitx ? II

More ideas on easy and cheap FM add on (RX) for the BITX transceiver...

With an TA7303 and a 10Mhz crystal between pin 6 and 7 ?...

The cheapest TA7303 I could find costs 1.03 Eur...

The above one is a little bit more tunable and probably uses more easy to find components...without a limiter in front you probably "get" AM as a bonus!

I have to test...

Have a nice week... this was my weekend:
