Smart SDR lost internet in the middle of tune

As far as I have experienced. I've had connectivity issues with my radio while tuning up and the thing just stays on and you lose all ability to do anything. (EVEN WHILE STANDING RIGHT IN FRONT OF THE RADIO) I have had it destroy two amplifiers so far, both times while tuning the amp after the swr was nulled. All you can do is start pulling stuff apart... I've tried going to the computer and shutting off TUNE, or MOX and everything is just flat locked up. I've tried hitting power off on the radio, the end is flipping off the power supply. I'd recommend a magic way to dump station power via one of those remote switches. But if the RF has taken down the internet at the router you're just sort of lost. My last explosion a week and a half ago, was I accidently had the 160 antenna on the amp... it doesn't go through my coax switch. I have to manually change it. I was tuning up I thought on the 12m beam. The whole shack was filled with smoke and the culprit was the power supply on one of the computers responded to the high rf in the shack and kerboom.... That one cost me a new supply $129.05 from amazon... it fixed it and brought the computer right back up. K0DD

yes there is,

I have seen this happen. I would be in favor of a heartbeat monitor which stops TX immediately if connectivity to the controlling client is lost (a "deadman" switch). Of course, this could itself fail due to the presence of RF at the chassis.
