Steve, in my experiments, I found that when setting the "Tune %" in the protection menu, you have to exit fully from the menu system for that setting to take effect. ?If I back out just one higher level and go to directly the Hardware test -> Tune SWR function, it does not take effect. ?But if I exit the menu system after changing "Tune %", it functions properly, and adjusts the Tune SWR power as expected (and also the SWR sweep power).
?
That helps explain why the setting did not always update.? However, I am still having the issue that my QMX+ puts out full power regardless of the setting.
