Acoustically coupled & way over driven, has what I hope is echo on trailing edges. Presumably from another receiver? There looks to variation in some element lengths & inter-element spacing (bother either shortened or lengthened by about 10 ms?) before N4LQ asserts PTT by pressing the front panel XMIT button. After that, no variations & consistent dot/dot-space/dash ratio near 1:1:2.5. Radio following keying I would have thought is basic stuff & 45 wpm isn't really all that fast. This must be something that was introduced after new/old QSK selection, as would have expected somebody to have noticed at the time, as folks then were looking at key closure & transmitted RF with 'scope, also with an eye on receiver recovery. 73, ex-VR2BG/p. ______________________________________________________________ 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
