I run my power supply at 14.0 volts as measured at the supply. This is
done to accommodate the ~0.25 - ~0.35 volt drop in the DC line between
the supply and the radio when in transmit.

Make sure your power supply provides enough voltage and can handle the power
draw (300 watts is probably a good number). This happened to me too when I
accidentally adjusted the voltage of my PSU too low. I now have it at 13.6V.

I seem to have low output on 75 phone. The most power I can put out is 71
watts. I can turn the power knob to 100 watts, but it backs down to 71
immediately. This is into an antenna and a dummy load.
I just checked 160 same thing except I get 83 watts
All other bands seem OK
