red pitaya power

I'm unable to set TX power to more than 1W. Tried setting Tired Tune Percent to 100, also normal TX using FM mode, Set PA calibration to 100, still no more than 1W out.

To increase output power you need to lower the value in the PA calibration. Let me know if that solves the problem.

No, it appears that changing the PA calibration value does not change the power output at all. Trying this in FM mode, drive is at 100%, cannot achieve more than 1W output . I can reduce the power to less than 1W by lowering the TX drive of course.

I found that changing the PA calibration for the 20M band - changes my output power for 80M...??? Same setup as before using FM mode in TX:

Update- it appears that setting the PA calibration for the 20M band also changes power output on other bands - 160, 80,40, 20 ....
