Re: [Elecraft] QRQ + and the K4 question
With AGC-F set to 200, "new" QSK, tnd the new synthesizers, I can just barely hear between the dots at 24 wpm. (non-QRQ mode). That's the only thing a miss about my old FT-1000D. No one misses the key clicks. 73, Scott K9MA On 12/6/2019 12:26, Wayne Burdick wrote: The K3 can only hear between words above about 10 wpm, and QRQ mode doesn't help much. This depends on how the K3 is configured. There are two QSK settings (see CONFIG:CW WGHT menu entry), and with one of them, along with proper adjustment of AGC, it's possible to hear between dots at well over 20 WPM. The new synthesizer (KSYN3A) also improved QSK times. -- Scott K9MA k...@sdellington.us __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Since the K4's signal processing for CW is primarily in the time domain, it has a distinct advantage over those that batch-process signals using FFTs and IFFTs (frequency domain). > The K3 can only hear between words above about 10 wpm, and QRQ mode doesn't > help much.

Re: [Elecraft] QRQ + and the K4 question
A related question: Will the latency and turn-around time of the K4 be fast enough for true QSK operation? The K3 can only hear between words above about 10 wpm, and QRQ mode doesn't help much. 73, Scott K9MA On 12/6/2019 09:13, Wayne Burdick wrote: As an SDR, the K4 has no need to shift an oscillator between RX and TX mode.

Re: [Elecraft] QRQ + and the K4 question
As an SDR, the K4 has no need to shift an oscillator between RX and TX mode. So there’s no need for “QRQ mode.” Wayne N6KR elecraft.com > On Dec 6, 2019, at 3:58 AM, Steven G.
