Years ago Gary made a relay-driven protector

when it was seen that a large RF signal could

damage the circuitry of the transceiver’s RX2

port.

?

It turned out to be an excellent RF amplifier

keying driver as the high quality of the driver

relay provided a worthwhile isolation.

There are a number of available products

these days, I hear. Like ?I.C.E. Products,

the KD9SV stamp is to investigate.
