Hello David,
As long as you are staying around the same frequency, ?the modulation mode should not impact the accuracy of the power measurement. ?The meter is not the issue. ?SSB transmission uses

Re: uBitx CW vs SSB output - Is it my cheap meter?
Just as a follow up, I did see something in the ebay ad now that I look at
it again. They say:

Re: sBitx v3 - No output
I did. Same situation. It almost is as an oscillation such as un

Re: sBitx v3 - No output

Re: sBitx v3 - No output
Well this is odd. In the middle of a cw qso on 20 meters, version 3 sbitx,
the power went up to about 35 watts out with no code pulses showing up on

Re: Latest Processor
It is funny how little is the distance between the all analog, minimal
bitx20 and the sbitx. Not much is different but for the Si5351, a

Hi Scotty;
The work-around for this bug is to set the task bar at the top of the screen to auto-hide.
A proposed software fix is on github being reviewed now.

Re: sBitx v3 - No output
It looks to me by this thread, that one must always keep a working version
available. First determine if it is software or hardware before opening to
