My V2 is working well but I can only get 3 watts out on 17 meters. All other bands have higher power. I've done the latest ./update of the software and also the txcal command. I have adjusted the scale coefficients on all bands to have no more than 25 watts out on CW to be conservative. Despite increasing the scale coefficient for 17 meters it tops out at 3 watts. This is into a dummy load. I have even tried a new sd card image and there's no difference. Here are the power outputs (Drive = 100, with hw_settings.ini scales adjusted, and on 10, 12 and 17 M maxed out):
10 M???? 10 Watts
12 M???? 13 W
15 M???? 25 W
17 M?????? 3 W
20 M????? 24 W
30 M????? 25 W
40 M????? 24 W
80 M??? ? 22 W
I would think it might be a PA transistor or driver problem but why would it be on one band only? And I used to get much more power out on 17 meters. Again it doesn't seem to be a software problem because I even swapped out sd cards to run a different image from a file saved that worked before. Could it have something to do with the LPF circuits? But 17M doesn't have its own dedicated LPF line and all other bands work.
Suggestions?
