Hi Tom,
The problems I described are unique to the K3's CW PTT mode, you wouldn't be aware of them if you use QSK. My CW keying is both from Win-Test via the USB port (it works perfectly) and into the K3 key and PTT connectors from the K1EL Winkeyer (the Winkeyer works perfectly for manual keying from a paddle except for the unwanted long VOX delay that the K3 applies to the external PTT input). When are you coming back to a W3LPL multi-multi DX contest to show us how to work hundreds of 80 meter JAs again? :) I'll never forget that weekend on 80 meters, its never happened to nearly that degree again, and certainly not on both mornings! We're still using the same 2 element quad at 170 feet,, but we now have a much better receiving antenna, a W8JI/W5ZN 8-circle receiving array. 73 Frank W3LPL ----- Original Message ----- From: "Chester Alderman" <[email protected]> To: [email protected], "Elecraft Reflector" <[email protected]> Sent: Tuesday, February 14, 2017 3:53:30 PM Subject: RE: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior First, I admit to not understanding the problem! I do run QSK and VOX during contest and during regular QRQ QSO's. With my K3/Alpha 9500 setup, I can run full QSK CW up to 100 wpm and I have no PTT delay issues? I do not run with PTT asserted and therefore I do not witness the issues other contesters have.. As for N1MM's "poorly designed internal K3 keyer logic", I certainly have to disagree with that comment. During 'normal' contest I operate from 28 to 40 wpm, full QSK and would go nuts if there were any perturbations with my K3's keying. A so called 'solution' to CW stuttering is to purchase and use the K1EL keyer. The real problem is with Windows op system wherein the CPU is often interrupted to do 'internal chores'; and when this happens, all I/O ports are shut down, which causes the CW stutter. Simply turning off the Windows generated sound, eliminates the stutter issue and the 'requirement' to purchase the K1EL keyer. 73, Tom - W4BQF -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of [email protected] Sent: Tuesday, February 14, 2017 12:53 AM To: Elecraft Reflector Subject: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior Okay, lets take Eric's lead and open an interesting thread directly related to an excellent Elecraft product. For years many of us have suffered with the odd behavior of the K3 in CW PTT mode. There are at least two inexplicble aspects of K3 CW PTT behavior that have forced many of us to use external Winkeyers rather than the poorly designed internal K3 keyer logic when the K3 is in CW PTT mode. For CW contesters, its necessary to operate the K3 in PTT mode to avoid unwanted VOX delay. But for some strange reason the K3 always applies VOX delay after external PTT is unasserted. I can think of no logical reason why VOX delay should be applied at the end of the external PTT input when the K3 is PTT mode or any other mode. When PTT is unasserted, the K3 should always immediately return to receive mode, no exceptions. When using the internal K3 keyer when in PTT mode, for some inexplicable reason the K3 behaves like its in QSK mode. The only way to avoid this is to use VOX rather than PTT mode or to use a foot switch when in PTT mode. Both alternatives are unacceptable. The band aid solution many contesters use with excellent results is to avoid using the internal K3 keyer and to use an external K1EL Winkeyer that generates both a key output and a PTT signal generated according to well designed Winkeyer CW PTT logic. Why can't the K3 implement logic similar to the Winkeyer to generate the equivalent of "Winkeyer PTT" when using the K3 internal keyer when the K3 is in PTT mode? 73 Frank W3LPL ______________________________________________________________ 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]
