Steve, do you know if you have your PF1 key to the left of the power button,
set the way you have yours, can you also have this same key set to activate
the tune function? Right now, I have that key programmed so that when I
depress it, the 590 goes into tune function, decreasing the power down to
around 10 watts and allowing me to tune my automatic antenna tuner for
minimum SWR. I use it all of the time for this purpose. Do you know if I can
keep it programmed to use this way, but then, also program it to work the
way you use yours when in transmit??
