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. 73 - Bill ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
