EMP is the ultimate zot - it induces current between metal bits, which are seperated by even a small distance.
This current tends to fry electronics.
Vacuum tubes are less succeptible to EMP than solid state - but they can still fry, given the right pulse.
So, the answer to your question...”IF HE IS NOT USING HIS SET DURING A PULSE (ooopppsss!) ...it will no longer work?”
...depends on what type of set, and how well he buried it. A faraday cage will work - but then, you cannot broadcast, can you?
Ping to my ham... ham operator hubby.
Resurrection of any broadcasting avenue would be priceless ... supposing there were others to receive/send like it.
Thank you, for the response. I appreciate it.
