KXV3A Utility Program 1 milliwatt calibration failure

[JohnDePrimo]

There was some chatter about this issue earlier in the year but did not see any clear resolution.  Like what others were seeing, the utility program successfully completes 5 and 50 watt calibrations but "settles on 0.1mw" when performing the 1 milliwatt cal; i.e., fails to achieve 1.0mw.

With the 5w and 50w calibration process, the power is automatically adjusted by the utility program to achieve the correct power level. However, the power does NOT automatically adjust when running the 1 mw cal. I can fool the program by manually adjusting power to 1.00 mw for each band but suppose that defeats the purpose.

There is a 50 ohm DL on the XVTR out in accordance with directions. Yes... Jumpers W1 and W2 were cut flush with the board. I have the latest FW in the K3. What's the next step?

Thanks & 73,

There was a change in K3 firmware around version 4.43 where we had to use a
different PC command to ask for 1 milliwatt out. The current K3 Utility uses
different PC commands to request 1 milliwatt depending on MCU revisions.  

If you're using an older K3 Utility you might see 0.1 milliwatt requested.

Hi Dick,
That did it, thanks. My utility program was not THAT old, but old enough - hi.
