Running 6500 + Expert 1.3k, Windows 10 SSDR and DDutil: I notice that the maximum RF power generated from my 6500 is on 10m at 115w and that it gradually decreases as I go down the bands to around 95w on 80m. All measurements/observations taken in CW mode. I also notice that after initially showing such power levels after only less than a minute the power gradually drops back by as much as 5 or 6 watts and will then stabilize a bit. This also seems to happen at low power levels which can be a nuisance when driving the amp as its power then starts to drop back substantially. Does anyone else see similar or can offer any thoughts? I have set the DC PSU voltage to 14v as read on DDutil. PSU is GSV3000.
