[Elecraft] P3 TXMON ISSUE

[Michael Murphy]

While working the NAQP CW contest this afternoon, I noticed that the TX Monitor was not always indicating the correct power or SWR.  Also the waveform was not always displaying properly (sometimes is is just a a wavy line instead of the usual waveform).

I took the cables off the P3 and the sensor box and reset everything.  I also refreshed the firmware in the P3 just because, but still have the same issue.

I did put a second wattmeter in-line ahead of the P3 sensor and confirmed that my power out and SWR is ok.

This is happening on various bands and antennas. I have not tried phone today, just CW.

Anyone seen this before?
