I agree with all you have suggested, Mark.  I too had questions about 
power output on the 910.  I discovered that the power to the radio was 
the culprit.  Before you send it away, check and make sure you have #10 
cables to the radio and your power supply delivers the correct voltage 
and current.  Mine does and it meets Specs on VHF and UHF on "both" my 
One I have the 1.2ghz Module in.  One I use for demos at field day and 
hamfests etc.
Good luck.
