[Elecraft] [K3] f/w 2.73/1.98 power calibration

[Steve Ward]

I just applied the latest beta firmware as I have done many times 
before, and it looks like this time my power calibration went out the 
window.  I'm putting out about 70w on PSK31 when I dialed in 45.

Just wanted to give folks a heads-up to watch their power output when 
they start operating under new firmware, it might be time to re-calibrate!

73,
