Thank you Klaus and others for the links and info , I have the day off today and have been playing around with the BITX40 on the bench this morning . I successfully changed the VFO freq to test rx on 20 m by using a 2.010 Xtal I had laying around. By replacing the VFO coil with the 2.010 xtal and bypassing the receive BPF I am able to receive BOTH 14 Mhz signal and 10 mhz signal (of course with no filtering …) from signal generator . Moving on to 20 m BPF on receiver . Any one know an easy mod to existing one on the board ??
