arghhrgh ARV.. this maybe:??? ? (cut and paste from Far Circuits site).
What I was pointing out that this PCB plus the old Farhan PCB were available from Far Circuits in Chicag for those who? wanted to scratch build a BIT x .."almost the same"..? Fred also has the old A Farhan analogue PCBs listed.?
This Bitx might be a bit deaf on receive. I'd be changing the 51R resistor ahead of the LC circuit/transformer on the receive front end. As in increasing it unless the circuit started ringing. Especially for use on 40 and 20 m.
The IFT 10,7 Meg cans shown , three off from old style FM radio designs are very hard to get as new items now.
74HC4053 analogue switch as used by Weber on RF? may be of great interest for those designing BP? filter banks as a relay replacement ??? Yall Heard it here first !!
