W4ZC sez: "And according to his <gulp> 20-part article, the spot level
automatically
varies in amplitude with the incoming signal (ref. Part 15, p. 4)."
INDEED, it does just that...he multiplies the envelope by the
software-generated sine wave sidetone, the result is a keyed sidetone
signal in synronism with the incoming signal. The envelope filter is
kinda slow, perhaps 0.1 second time constant: no key clicks on it!
And Lyle sez: "More to think about? Just what I need :-)"
I never got into emoticons but I don't envy your position, hi. For sure
I'm sure more important things than this. You guys do a good job of
saying "OK I hear ya", which is all most folks want to know. Peter was
bossless and a little cavalier about "customer" input. You better talk
nice to get him to listen with both ears! Once he decided to do
something he went at it con mucho gusto. Visions of a British Bulldog
comes to mind.
Bluntly, that autotune scares the shit out of me! It works: once in a
very great while I have to push it twice. But there's always a nagging
question of whether it's REALLY dead nuts on frequency, hi. 20 Hz? 1 Hz?
Zero beating the sidetone is crude manual labor, but one can obtain
whatever accuracy one desires IF the sidetone and zero beat precisely
correspond, which I assume is the case.
I'm juggling several things on the countdown to visiting Harold Johnson
and going to the Shelby hamfest with N2PK. So have not even plugged the
3.5mm patch cables into PC to do PSK31 or RTTY yet. For those modes,
especially PSK31, I want to REALLY be zero beat. So when the time comes
I'll wish my shack and workshop didn't have a door and 15 feet between
them because I'm going to want to play with this aspect of the rig a bit
before I try a QSO.
