Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

Hey Jim, I'm a contester... so go much above 45 and the rate starts to drop... but when I have a serious pile, I go from 38 to 40 or 42. So having a good sounding K3 is important. I used to be a QRQ rag chewer in my younger days -- wish I had a rig as nice as a K3 back then; 60 to 70 was my

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

Oh yes, The synthesizer upgrade isn't cheap, especially if you have two receivers (you have to upgrade the synth for each receiver, as one new one can't coexist with one old one, but from experience, I've found the keying sounds much cleaner with the new synthesizer, even at slower speeds and

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

"Clipped dits" is a good description. Upgrading the synth(s) will fix this, even with QRQ mode turned off. In fact it's so good, that I don't even use QRQ mode anymore so there is no change when RIT/XIT or Split modes are engaged. You'll also find that the K3 now accurately follows an external

[Elecraft] Mushy CW in QSK at 38 wpm and above...

I was operating VE4EA in NAQP this weekend... A couple of people said the CW sounded mushy. I was running QSK, with N1MM DTR CW Keying using the KUSB. I noticed, on the sidetone, that it got mushy around 40 wpm. I don't know Cary's firmware rev. Is there a fix for this? (This is with RIT

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

I don't know if this applies to your station, but if you are using a level converter circuit similar to the one in Fred's KX3 book -- 10K input resistor to NPN base with a diode to ground/emitter and a .1 MFD cap between the collector/output and ground -- this might apply. I was using the

Hi Vic, This is K3, not K3s, no synth upgrade (yet!). This is a KUSB cable for CW keying, Stock. You know, I've never really noticed a difference with QRQ on or off. But, I do see a big difference when I go between 38 and 40 WPM. I'll try the QRQ mode again and see. I'll also test with

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

Is it a K3 (not K3S) which did NOT have its synthesizer upgraded? If so, then you MUST have QRQ mode turned on or you will see poor CW above about 35 wpm. In addition, note that QRQ mode is automatically disabled when you turn RIT/XIT on or use SPLIT. 73, Vic, 4X6GP/K2VCO Rehovot, Israel

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

I don't think "mushy" is the right term. It's jitter in the CW envelope timing. Generally jitter is less than +/- 1 ms, but with the old synth, QRQ mode turned off, and the code speed in a certain range (around 40 WPM), it can be a bit worse. 73, Wayne N6KR On Jan 11, 2016, at 11:07 AM,

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

One listener expressed it as "clipped dits". I guess at 40wpm, 1mS would make enough of a difference in dit length. Thanks for all the feedback. 73, Gerry W1VE / VE1RM On Mon, Jan 11, 2016 at 2:39 PM, Wayne Burdick wrote: > I don't think "mushy" is the right term. It's

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

A K3 with the old synth will sound bad at 38 wpm with any keying method unless QRQ is on. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 11 Jan 2016 21:07, Gerry Hull wrote: Hi Vic, This is K3, not K3s, no synth upgrade (yet!). This is a KUSB cable for CW keying, Stock.

Re: [Elecraft] Mushy CW in QSK at 38 wpm and above...

Clipped dits would be close enough. Your ear knows that the starts and stops of bauds are not in correct relationship to each other and with other bauds, it sounds different, not right, but picking a word to describe that is hard. 73, Guy K2AV. On Mon, Jan 11, 2016 at 2:45 PM, Gerry Hull
