Yup. Great idea for the first time you observe this, and that's exactly what I did for a neighbor during WPX. 73, Jim K9YC _______________________________________________ CQ-Contest mailing list CQ-C
Don't stop there Jim, maybe you could provide a supplemental list that specifically calls out the rigs that are acceptable in this respect. And perhaps your objective metric that provides the dividi

One of the guys who had very bad clicks during WPX wrote me to have details, bands and time because he was using two different radio during WPX. I made 3 Q with him and spotted 2 times with comment D
With what funding? Isn't that the job of our organizations like ARRL and RSGB? So far, you state the FT2K as belonging in the "bad" (replace) category, On the basis of 6 msec being the slowest possib

On a related note, if I've done the math right, at 50 wpm, a dit lasts 24 ms, not including the following space. I can see how 10 ms rise and fall might sound a bit mushy at that speed. 4 ms would p
I think the fact that Elecraft can use around 4ms and get a crisp, yet completely click-free, keying unfortunately means that the other manufacturers simply haven't bothered. Although Elecraft would
Isn´t it also so that in the K3 the CW signal is also routed through a filter to limit the bandwith ? 73 Jim -- Den 2020-06-09 kl. 02:08, skrev Jim Brown: On 6/8/2020 1:12 PM, Jim Brown wrote: They a
I've had QSOs at 80 WPM with some guys having very sharp keying. I've never noticed clicks on any of them. Off hand, don't know what radios they use. Barry W2UP ______________________________________
Just a decade ago, CW contest signals with extreme power supply ripple (causing large sidebands +/-100, +/-300, +/-500 Hz but also out a longer ways to kHz in worst cases) were extremely common from
There are few, if any, K3 radios running pre-2013 firmware that added FSK waveshaping. The radio has always had AFSK filtering. Both types of K3 RTTY transmission are among the cleanest signals on
Yes. Although Elecraft would like us to think of it as a secret sauce, there is *no magic* to minimizing the bandwidth of on-off keying using envelope shaping. Any electrical engineer with a college
