Re: Selecting the correct BFO frequency

Kerr Smith

Hi Jerry,

Thanks for confirming this.

As I am going to be using a 3MHz VFO I think I will have a go and see if I can increase the BFO frequency up so it is above the crystal filter (or about 20dB down the side as suggested by Dave). I will try different values for the series capacitor and see if I can get it to move up to the required location.

Thanks for the link as well, this is another circuit I can have a go at creating - it looks quite an interesting one.
