Wondering if anyone else gets this problem. Loop ATU tunes to lowest SWR, transmits okay on FT8 for a couple of times and then suddenly a blip on the SWR knocks the Amp out. Retune and same thing will happen again. No wind. Rotator not moved. Loop fed by 30m of RG213 cable. Supporting pole earthed.
Grateful for any suggestions as to what might be causing this?
I get the same on my Baby Loop. The wind causes it to de-tune and trip my amp. Also when it rains a similar thing sometimes happens and I think RF maybe flashing over the insulator guide on the lower frequencies as I have a burn on one of them.
