Tom,

My suggestion would be to check option three from simpleusb-tune-menu 
and adjusting the current setting downwards.
---------------------------------------------------------
Please enter your selection now: 3
Current setting on Tx Channel A is 350
Enter new Tx A Level setting (0-999, or C/R for none):
----------------------------------------------------------
I have found this necessary when changing or testing node radios.

Ian..
