Subject: Ramsey PA20 power amp



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.
