Re: [Elecraft] Basic Info
Don, I just ran full QSK test on 10m this morning, up to 70 wpm, and both the K3 and the Alpha 9500 sounded very good to me, after resetting TX DLY down to 08. However I'm not sure how it would sound on the other end. Hopefully today, if I don't get flooded out of here (6 inches of rain yesterday and more rain this morning!), I'm going to hook up my IC-7700 and listen for myself. I am quite impressed with what I hear via the K3's sidetone. 73, Tom - W4BQF -Original Message- From: Don Wilhelm [mailto:w3...@embarqmail.com] Sent: Friday, July 15, 2011 9:03 PM To: Tommy Alderman Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Basic Info Tom, I know nothing about that particular amplifier, but I offer a few in general facts.

Re: [Elecraft] Basic Info
Last time I looked at Waddle K. Knowitall's Authoritative Real Meanings Dictionary, 70 wpm, indeed 50 wpm was QRQ all the way. If you want QSK, you should set the TX DLY to minimum 8 and leave it there forever. I don't like the way it behaves at higher delays anyway. If you want to keep RX from opening in certain contesting situations, do it with the logging program and it's PTT setting and pipe the logger supplied PTT signal around. You will find that your 9500 and the K3 are slick together. You CAN use the CW+ fast QSK, but this is a fight in the K3 against RX-TX-RX transition tasks. e.g. CPU time in the firmware, and in order to be really fast some functions are disabled. You will need to decide if the disabled functions are things you can do without. 73, Guy.

Re: [Elecraft] Basic Info
By common usage, the language has moved beyond the old CW procedural meanings. QRQ clearly also means faster than common usage. Same thing for QRO, which has more of an absolute sense these days. Otherwise how would you interpret the sentence, Do you consider 35 WPM QRQ? 73, Guy. On Sat, Jul 16, 2011 at 5:31 PM, Ron D'Eau Claire r...@cobi.biz wrote: It's all relative.

Of course they are...go for it.

Re: [Elecraft] Basic Info
Tom, In the original release notes for QRQ mode, Wayne stated: Note 2: If you use CONFIG:TX DLY to set external keying delay, you may need to adjust its setting for QRQ CW use. Also, any increase in the default (8 ms) may decrease the maximum available CW speed. It stil is not clear to me exactly what this meant. I used the scope to look at the timing between KEY IN and KEY OUT to determine that increasing the parameter above 8 msec had no effect on the timing. And as mentioned previously, the delay is not equal to the value of 8 msecs. It is on the order of 4 to 5 msecs, so the 9500 relays must be able to switch faster than that. I believe what I found happening when the parameter was changed from 8 to even just 9 was that the KEY OUT line quit following the keying so that you effectively had semi qsk. A long interval of key open was needed in order for KEY OUT to go high again. I would need to check my log notes from my testing last August to verify this result, but it was something of this nature. Even when set to 8, KEY OUT starts to hang low (not follow the keying) at about 65 wpm so the QSK begins to degrade at that point. I would prefer for it to continue unblemished up to 70 wpm, but I hardly ever run 65, usually 63 max, so I remain very pleased with the performance.
