PA20
Those who have a RAMSEY Electronics PA-20 220 MHz power amplifier ( 2in - 10
out) may have noticed extensive TVI on channels 11 and 13.
The fix is to replace the PIN diode at the xcvr input end of the receive
pre-amp with a MPN 3401 or similiar unit with higher isolation than the
original.
Problem solved 73 Bill.
