[Elecraft] P3 Transmit Display Failure

[hawley, charles j jr]

I have a reoccurring issue with the P3 display of the transmit cw display. Occasionally, the P3 doesn't display the TX waveform ( I have never noticed if this happening on SSB...probably not since I have never had to fix it). The fix is loading a config file stored when the problem was not happening.
I have tried to store a config file when it was happening just to see and then restore using that file. What happens then is the P3 display locked up with a dit and could not be unlocked.
After this test, I had to turn off the K3s and unpower the P3, restore power and turn the K3s on, and restore with a copy of the config which was taken when the display was showing transmit cw.
I'm thinking stray RF somehow causing this but never happened on SSB...and I have no clue what is getting flipped in the rig or P3 to have this happen.
Since I can restore the config and fix it, I guess I'm mostly curious why it's happening, any ideas?
