Thanks Dick,
I tested my 765 into 50 dummy load and power meter
WM-1 is good. The power supply is ok and voltage is
13.8 V.and Ic=11A so a bit less than other bands 15
-17 A. Power on 27 Mc is 100 Wt but go down up to 60
Wt. fluently when I change freq. to 28 and upper.
May be something wrong with band pass filter 28 after
PA?

73, VE3KF
Alex.
