    Testing power output on a complex impedance load (antenna) is not an accurate way to measure the power output of the PA.  It needs to be a resistive (dummy) load.  And you have to make sure you are delivering 13.8 VDC at the radio under load to the radio when transmitting to make full power too.

    If you think you have a hardware issue, you should submit a HelpDesk support ticket.

    My load is a bird termaline and is resistive. No big deal. The extra ten to fifteen watts makes a bigger difference with the amp on and in restricted on antenna space so the extra power on the amp might make a little difference, but the radio works fine. Tim, are you saying seven tenths of a volt is going to make a ten to fifteen watt difference?

    Good point about driving the amp.

    Scott - yes, possibly depending on the frequency.

    Just confirming that by removing my MFJ DC distribution box, I am at 100 watts now from 80. Sigh. Scratch another one up to keeping it simple pays off.

    I had the same fix. Flex is wired directly to the p.s. with ring terminals under the binding posts. Other stuff like etc. fed through the distribution box.
