As I recall the FT-1000D accomplished that by shortening the dits and producing an astonishing clatter.
THANKS, 73 ED W2RF -----Original Message----- From: [email protected] <[email protected]> On Behalf Of K9MA Sent: Friday, January 17, 2020 12:26 AM To: [email protected] Subject: [Elecraft] Full Break-In (QSK) One of the things I miss is being able to hear between the dits, not just the letters. I know part of that is due to the inherent latency of DSP filters. In any case, I finally got around to actually measuring it. I just used a keyer with 50 percent weighting, and N1MM to set the speed. I found that the K3 could just barely hear something between the dits at 22 wpm, while my old FT-1000D could at 34 wpm. Both at 500 Hz bandwidth, fast AGC. The K3 has the new synthesizers. I did the test by listening to an S-7 carrier and sweeping the RIT back and forth while transmitting dits. Below the above speeds, I could just detect the change in pitch. Increasing the bandwidth and turning off the AGC didn't make much difference. I didn't try the QRQ mode on the K3. It will be interesting to see how the K4 compares. 73, Scott K9MA -- Scott K9MA [email protected] ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
