[Elecraft] Downloaded DSP1 revision "02.88". Radio responded with revision "00.00"

[Nr4c]

I’m not sure why disconnecting the radio and reconnecting again should require a firmware reload.  

Did you try reloading the latest CONFIG file?

I reloaded the firmware and the K3s Utility failed with Downloaded DSP1 revision "02.88". Radio responded with revision “00.00” Turned off and back on again and I am still getting ERR DSX.
