During a recent contest, one speedy cw op was cruising something over 30 wpm
but was hard to copy as there was no tone at all on his signal, nothing but
key clicks were being transmitted. No, he was not near me. Unknown radio.
Not something I would want anybody to identify me with sending.
I'm surprised to read of resistance to this enhancement, anything that
helps sell more K3s is good for me.
There are some really good QRQ ops out there. W4BQF and W2UP come to mind.
I know that W4BQF routinely copies and sends over 100WPM, and he uses an
Icom 7700. Having owned the '7700,

This is a *little* OT, but I've just read in a 1914 WT book that they were
regularly running at 300wpm on spark transmitters. The very clever trick
was to operate the spark continuously and FSK it by switching between taps
in the antenna tank. The receivers were direct conversion using rotary
Who the heck is copying that and what are they copying???
The highest speed record for a long time, of copying

the whole time I was growing up, and it was from the 30's I
think.
It is certainly impossible to copy 300 WPM without

A breaking station sounds like a clicking sound instead of a tone on the K3
at speeds over 30-35wpm but at least it can be heard. The main problem is
with keying irregularity. Yes, the dits are a bit short but that can be
compensated for. The real problem is random variation between characters.
While it's gracious of you to give the K3 the benefit of the doubt in the
hands of QRQ QSK gurus, I'm also not convinced this is a true failing of
the K3, if it's true (my K3's dits sound ok to me at 50wpm full QSK, tho
slightly shortened).
In fact, compromise is a hallmark of good design. The

Because if you are using something you can measure, like two tone, the

before an AGC loop or loops bite and settle takes some pretty

I agree with Guy and Vic. It is not good to load up an amp and use AGC to

Yup, ALC is not feedforward correction system. It is a servo like mechanism
that corrects after the distortion has left, then it corrects. For SSB
