Re: What's a Reason for less Power Output ONLY get 4W on 80m?.., 3-4W on 40/20m, 1W on 15/12/10m #ubitx #ubitx-help


I would ask questions like:

What is the DC applied voltage during TX?   It sounds low for CW even.
For CW I'd expect near 10-12W however if you Power supply is below
12V what you are getting is then good.

What is the mic level or if your using a tone osc what audio (AC) votlage?

is the bias correctly set?

IS the calibration done correctly? is the sideband carrier or the second
conversion is off the band pass filters (crystal filters) will eat your RF.

NOTE CW is done differently than SSB so if SSB is more than half the CW
something is wrong. 

Look at the obvious before progressing.
