[Elecraft] KSYN3A Upgrade Observations

[Tighe Kuykendall]

Interesting observations after upgrading my K3 to the KSYN3A this evening.

1. I was already running 5.14 firmware.  After installation I upgraded 
to 5.29 but the DSP was already at 2.83 so I only sent the MCU and FPF 
firmware. After the upgrade I started getting ERR DSE. Reflash of all 
firmware corrected the problem.

2. I had recent success with the TX gain calibration for the 5.14 
upgrade.  After fixing the ERR DSE issue with the firmware reload, the 
5w TX gain calibration failed on 40m with error of it settling on 5.4w. 
  I'm using the latest K3 utility on a Mac to perform the calibration. 
I ran it again with the same result but this time proceeded on to the 
50w calibration which succeeded.  I then re-ran the 5w calibration and 
it was successful.

All is working well now and I'm happy with the upgrade.
