K144XV power output and tune mode

Pierfrancesco Caci

Am I supposed to be able to set any arbitrary power level between 0 and
10W on the K144XV? It looks like I can't go below 4-5 W, and the
relation between drive and output looks like it's extremely non-linear.

drive    output
0.1 mW   4.2 W
0.2 mW   6.6 W
0.3 mW   8.5 W
0.4 mW   9.5 W
0.5 mW   9.7 W
0.6 mW  10.0 W
0.7 mW  10.6 W
0.8 mW  10.6 W
0.9 mW  10.6 W
1.0 mW  10.6 W
1.5 mW  10.6 W

drive as indicated by the K3, output is measured with a W2 (but I got
similarly looking results with a Diamond).

Seems to me there's no point in using more than 0.6 mW drive.
Also, does the transverter have a concept of TUNE power? Changing power
while in TUNE seems to also change the normal power setting.

Thanks for the attention

Hello

Mine is much the same - it can run from about 3w to 9w max. It would be
great to have a larger range of adjustment in a more linear progression.
