This question is really a spin-off from the "Power Control at 50-MHz".
I measured CW output with PWR set to max on the HF bands with my
Bird-43 power meter into a dummy load. I found that a setting of 12w
actually netted near 16w output 160-20m, but dropped to 8w on 10 &
6m. I didn't do a pow
Hi Joe,
If you've already narrowed the filter and tuned the signal in properly
(with the aid of CWT), the next step is to adjust the threshold of the
decoder. Hold the TEXT DEC switch, then use VFO A to adjust the
threshold until the CWT icon blink is closely correlated with the
incoming C
So that begs the question, I suppose -- is CW sent by a keyer with paddle
machine-sent or hand-sent? It's actually both, of course. Some of the
metrics are controlled by logic (hardware and/or software), but
inter-character and inter-word spacing are controlled by the human operator.
In my expe
Joe.
If you are trying to decode hand sent CW. you will likely have to
provide a lot of "fills" unless the sending operator is quite skilled at
timing and spacing. Machine sent (keyboard or computer) CW should be
easily decoded.

I doubt the current problem has anything to do with 4.03. Something appears to
