In this recent discussion here on K3 QRM from strong local broadcast stations,
W4TV brought up the noise generated in the T/R switching diodes. In doing
some experimentation with a bandpass flter in the loop between the RX antenna
out and in on the KXV3A I have discovered something which has
The intermod is generated in the T/R switch, which is before the RX
IN/OUT circuitry, so putting a filter in the loop won't help. It must be
between the T/R switch and the antenna, which means it has to be able to
handle transmitter power.
There is a T/R switch in the KPA100 and one in the
