Just made up an Express PCB mask and etched it, got to drill it yet for the RX side of this, with a modification where I added varicaps (Will start with MVAM109 but could use red LED) and a potentiometer which will make the crystal filter width adjustable. I have a few different IF crystal selections too and might start with 4.9152MHz and as I will use a FCC-1/FCC-2 I should be able to make this a little more frequency agile by adding a bypass to the BPF.M1KTAhttps://www.blogger.com/profile/05944098903387301523noreply@blogger.com
