I'm happy soldering here, but have a question:
In the text for the BITX20 it says "If you are using this for 14MHz
and above, the BFO will need a coil in series with the crystal".
This is what I have done - seems to work OK (see G0MGX folder in
pictures on reflector).
I just saw the alternative coil data that has been posted on the
reflector and that says "L3 was used in series between the crystal
and the 22pf trimmer cap plus I added 7pf Mica fixed cap across the
trimmer. Needed for USB"
I am therefore confused!
Can anyone shed any light on this?
