Did you try it on FM on the same frequency, Bud... or did you move 2-3 MHz up in our current bandplan around here, to go to an analog FM repeater? ;-) Try FM mode on the D-STAR input. (I know, naughty naughty... do it when no one's on the system...), eliminate the variables... I've seen (way) out of alignment rigs draw significantly more current (and put out more power) at one band edge than another, into a solid 50-ohm dummy-load... rigs being generally commercial 2-way rigs moved into the ham band, not rigs DESIGNED for the ham band, but worth a mention... -- Nate Duehr, WY0X [email protected] facebook.com/denverpilot twitter.com/denverpilot
