My newly acquired 30 year old amp comes with QSK. As there was a
different relay than came stock I have to assume the circuitry may
have been altered in the past. I have no way to know this.
After two weeks of normal amp behavior I found the T/R vacuum relay
had locked in the transmit position.
Config menu item TX DLY, on page 61 of the K3 manual.

Gary,
The config menu TX DLY parameter will change the time from keydown to
the onset of RF.

Do this at the risk of QSD CW. Higher settings (>10ms) cause this.
The bad keying is independent of internal or external keyer.
It is a bug that has never been fixed in the K3.

My TX DLY setting is 015. If I've got it this high and I still had a
problem, this makes it difficult for me to know what to do; I use QSK
much more than any other mode/setting as I chase DX and do not want
to transmit while the DX station is replying to someone & hopefully
me. I can use semi b
It's an old Alpha of the 77DX/SX clan. Unfortunately there's nobody I
know of around here that knows these amps & it's too heavy to ship so
I'll have to do my best and amp repair/schematic wrangling is not my
strong point. There is a Kilovac relay in there and Alpha always used
jennings so some

Igor,
Just what does this delay?
Does it inhibit RF output from the K3 for 30 ms? If so it may chop
parts of CW characte
Unfortunately, this doesn't help when you are using a paddle or want QSK!
