K3 Power Output Issue after Firmware Update

[David Inger-2]

I just updated the K3 firmware to 5.10 since I am about to order the new
synth board.  When I restarted the radio after the upload, the following
problem occurred:

When I press the TUNE button, the radio shows about 8 watts of power.  
If I turn the power control up, the display defaults back to 8 watts.  
In the config menu I have the tune power set to 20 watts.

I reloaded the firmware to make sure there wasn't a glitch in the
loading.  The same problem still occurs.
The only other troubleshooting I did was to change the TX ALC (in the
config menu) to "OFF"  When I tune up with the TX ALC off, I can get
full power out from the radio,  so I assume that I do not have a
component failure problem.

Has anyone experienced this or know of any settings which I may have
inadvertently changed?

You need to re-do the power calibration using the
K3 Utility. See the document for the Synth board.

Sorry. See the F/W 5.10 documentation :-)

Yes, the instructions for 5.10 and later state that the TX CAL must be
performed after loading 5.10, 5.12 or 5.13 (and presumably later).

In the Notes Here: http://www.elecraft.com/K3/k3_software.htm

"
Those loading rev. 5.10 (or later) for the first time must re-do the 50-Watt gain calibration step on all bands.Once this has been done, there is no need to do it when loading future firmware releases.
