Does the 959 have a l.e.d that lights when the swr is high? You could use that to drive a transistor that opens a relay in the tx line from the microphone.
Really? I assumed that nested dipoles work on the same principle. The rf goes the path of lowest swr. And don't say that the impedance of the dummy load and the antenna are too close because I have heard of hams using nested dipoles all cut for the same band to make their station more...
You can get skip on any mode though it's easiest on USB/LSB. There are any number of reasons for transmitting on more than one channel such as an overdriven or badly designed amp or impedance mismatch on the microphone. It's not guaranteed that a cut am limiter will cause splatter but it depends...
You could make a 100 ohm dummy load for the radio and hook it in parallel to the antenna coax. That way if the antenna swr rose above 2:1 the radios output would dissipate in the dummy load instead of the antenna. It would save the radio just the same.
Nobody "goes" to Dxland, they wait for Dxland to come to them. Dx land usually occurs during working hours. If you have a job then when you get back there could be nothing on the radio.

My 2970n2 had a similar problem. After it tx'ed in to a high swr antenna it gradually lost more power until it only did 40watts ssb which was garbled sounding. Am/fm power was down also but the audio was okay.The rf meter on the radio woundn't swing fully either. A tech resoldered some joints...
Right you are captain. I found some more about racal radios here All about Racal RA3701 and RA3712 Receivers if anyone is interested. It looks like it has a rs232 port so no remote head needed.
I looked up a capacitor cheat sheet. I think its 4000pf doorknob. There's a few on ebay rated to 20kv at the moment. Anything over 3kv should be fine. I could be wrong about the code as I don't know what the z is for so hopefully someone else will chime in.

I'm not going to buy this one but I was wondering is this an sdr like the mororola micom 2E? . I see very little on google about it.
No I see nothing there to indicate you're crazy. If you had visual snow or distortions in depth perception that could be worth looking into.

The heat from the flashlight could cause turbulence in the air near the lens. I've often seen vapour rising from the lens of powerful flashlights for 6 feet much like your breath would turn in to vapour on a cold day.
Power is not an issue. You can run 128 speakers if you want to so long as you match the impedances but the volume on each speaker will drop. Calculate the impedances of the speakers the same way you would with resistors in series or parallel. Examine the Y adapter to see is it a stereo or mono...
Nice job. I've been thinking about building something similar since I got my ticket recently. You could strengthen the antenna in the lower pic up a deal by drilling pilot holes where the two plastic pipes overlap and screwing in a timber screw. What do you plan to use as a rotator if any?
