Don, I have now done more tests and bandpass filter alignments....Don, As you suggested I checked all the voltages in the Elecraft manual on the RF board. All are good...
Here is the (MAX) power (OUT) int a dummy load on each band and I noticed something that was peculiar. 10m = 2 watts 12m = 2 watts 15m = 3.5 watts 17m = 4 watts 20m = 5 watts 30m = 10 watts 40m = 12 watts 80m = 12 watts 160m = 4 - 5 watts I notice while on 40 meters that as I decrease the power setting the power out peaks a tiny bit at he 12 oclock position to 13 watts and doesnt start decreasing until I get to 10 oclock and as I turn powerback up after I get past 12 oclock the max power drops off by 1 watt. What do I test or change next? is my driver transistor at fault, just not driving the finals??? Trying to get this resolved before the CQ 160 Meter CW Contest on the 27th, need a true 5 watts during the contest and to not harm my rig during the event.
