Re: [Elecraft] QSK the K3
I have the old synthesizers (K3 S/N 1428 running version 5.29) and, although I don't often use QSK, I did check after seeing Bill's comments. I believe Bill is right and the QSK response does appear to be slower. I normally run cw between 24 and 32 wpm. I did set CW QRQ to on and it does seem to switch faster but it's hard to quantify. Are there any other parameters to change for those of us who may not upgrade synthesizers? Tnx 73, Gerry, W1GD Bill, There were some firmware changes made when the new synthesizers were introduced, and as I recall some of those changes involved QSK operation. Initial reports on the new synthesizers from users indicated that QSK was better. I have not seen any reports of QSK changes with the old synthesizers, but you may have hit on something - continue with the tests and tell us your results. 73, Don W3FPR On 7/16/2015 10:00 AM, Bill Stravinsky via Elecraft wrote: When I first got my K3 in 2009 I thought the QSK was fabulous and used it every so often. Then for a few years I was working too much and wasa little inactive. I finally retired and heavy into ham radio once again. I got the KXV3B for the preamp and had to jump from version 3 somethingmcu to version 5, and now have version 5.29. Has anybody else thought the QSK to be slower? I am performing some tests recommended byElecraft to see if I have a problem but am looking for opinions from other users.

Re: [Elecraft] QSK With K3 and KW Amp
I've run my SB-1000 with QSK-5 pin diode switch with no problems with my K3 using the KEY OUT signal. -Mike, AB9V Ed G wrote: Hello, Is any anyone using one of the old DEO QSK-1500 full QSK switching units (or the similar PIN diode QSK unit from Ameritron) with their K3 and external amplifier? I haven't yet received my K3 but I would like to hook it up with my Heath SB-220 to run full QSK. I suspect that I will need to use an external keyer (and not the one internal to the K3) to trigger the PIN diode switching electronics. Same deal with software-generated CW. If you are running full QSK this way with your K3, let me know if you experienced any problems setting up the switching, and if you are successfully running contest/computer software in the CW mode with full QSK. --Ed, N3CW-- __ 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 __ 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

Not quite sure why you think an external keyer would be required. I use my K3 driving an AL-1200 with an internal QSK-5PC -- the K3 keys it just fine, with no hotswitching on either key down or key up.

Re: [Elecraft] QSK With K3 and KW Amp
I worked with Doc Sheller on the DEO QSK1500 many years ago ... With the current behavior of the K3's Key Out jack, you should be able to use the FT-757 instructions in the DEO QSK1500 manual (K3, Key Out to QSK 1500 Amp Rly In, and QSK1500 AMP RLY Out to the SB-200 PTT line). The QSK 1500 will follow keying from the K3 ... If you want to add an extra level of safety, connect a pull-up resistor between +5V and the K3 INH input and connect the QSK 1500 Pos Key Out to the INH input of the K3 (close to ground to allow RF). 73, ...
