Hello Ray
I built an RF limiter to put in my 2nd receiver line. It consists of two
toroids and a pair of 1N914 or other fast diodes. Basically you step up
the impedance to a pair of diodes and then step it back down to 50
ohms. Mine limits nicely at about 0 dBm or so. You can buy similar
stuff at DXE I think.

….thanks to comments and suggestions from K9ZTV and W2CS.
My K3 has the Sub Receiver installed, and I have been playing around with
diversity reception, using a random wire connected to the sub-receiver
antenna input BNC connector. Apparently the carrier operated relay that
protects the receiver from overload is being triggered by lots of RF coming
into that random wire. When I disconnect the receive antenna, no more
clicking. Now that I know what it is, I'll just ignore it. Or maybe someday
I'll rig a manual T-R switch arrangement to disconnect the sub receiver
antenna except when actually using it.
Thanks, gents!
