Hi Gordon,
Thanks for the note.? Apologies for being dense. I did tune to 10.000 - no tone.? The tone is on 10.002.100 on my radio.? So first step - what do I change to get the frequency to display accurately?? Second,? after tuning to 10.002.100 I did use FLDIGI to look at the waterfall but I don't see anything that indicates the tone is 500 or 600 Hz.? I was using the speaker on the ubitx and the mic from my laptop - just audio to audio.? Do I need to direct connect the ubitx to the PC?? Perhaps I don't know how to setup the waterfall display in FLDIGI - but what I see looks nothing like what I have seen on web videos.? I set mode CW on FLDIGI and dialed? in 10.002.100 on the ubitx - nice clear tone.? Nothing on the waterfall display in FLDIGI looks like a 500 or 600 hz signal to me.? Perhaps I also don't understand how to setup FLDIGI.
I also don't understand what you mean by the following:?
"Then calculate the correction, apply it to the source code, recompile.?If you are using some product ccode, apply corrections until you get the tones to be perfect." ??
