Re: [Elecraft] Mac utility with K3S Puts K3S in TX mode!
Correct, the driver did it. Apple provides a driver for FTDI-based USB-serial devices. That driver unconditionally asserts DTR and ignores attempts by applications to turn DTR off. When you install the FTDI-provided driver, it takes precedence over the Apple driver and behaves more responsibly. I filled a bug report about this; Apple marked it as a “duplicate” and closed it.

Re: [Elecraft] P3 forgets set ranges in Fixed Track mode (WARC)
My P3 routinely forgets the per-band SPAN when I set it using software commands instead of P3 buttons. Doesn’t matter which band, and the SPAN is remembered properly if I press the corresponding FN button for the computer-set SPAN before I change bands. My P3 also forgets the per-band REF LVL setting, but not always and only on 160m.

From time to time the P3 forgets the setting on the 17 and 12 meter bands only. I'm wondering if i am the only person that has experienced this issue. I can't pinpoint exactly how this happens but I am usually operating on 10 meters when I change bands and discover 12 and 17 have had the fixed track frequency I set disappear. I have never complained before as the reset has been infrequent. Now, with 10 open, I find this problem occurs daily, sometimes two or three times a day. Not an earth shattering problem as the P3 works fine and I change the setting back, just an irritant. I'm wondering if it is just my station or have others experienced this, remedy anyone? __ 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
Re: [Elecraft] KAT500 producing S4-5-birdie on 28004.5
Aire, Yes, that spurious signal on 28.004.5 is real and generated within the KAT500. Recent KAT500 beta firmware optionally shuts off an oscillator inside the KAT500 to suppress the spur. The oscillator is automatically turned back on by a number of events, such as pressing a button or transmitting. The oscillator is also turned on by activity on the KAT500 serial port, which means that software like mine that polls the KAT500 to keep track of antenna port selection also keeps that spur alive. Sigh. Bill, K1GQ On 2013.06.29, at 07:02, Arie Kleingeld PA3A p...@xs4all.nl wrote: Hi all, KAT500 + KPA500 connected to K3 through coax and elecraft interfacecables.

[Elecraft] [KAT500] 10m Spur
Mine generates a clean S4 carrier at 28.004.55. Does anyone else see this, or know how to move it out of the band?

The only way to completely suppress my spur is to remove 12VDC power to my KAT500 by disconnecting the power cable. Turning the KAT500 “off” isn’t enough because the internal electronics are still alive.

Re: [Elecraft] [KAT500] 10m Spur
I’m using Elecraft cables for both connections; those cables have beads on each end. I added two more beads to each cable while watching the spur level with the K3 dBV meter; no effect. FWIW, I’ve heard from two others KAT500 owners that hear the spur but didn’t post to the reflector. The spur is obvious on my P3.

For the life of my I can't figure why you would want to be changing frequency while transmitting CW (or any other mode) I'm the author of the post that Bill (W4ZV) quoted. My experiments with the PowerMate are recent and on-going. I'm considering modifying my software to support more than one PowerMate :-) It's rather handy to be able to change the *receive* frequency while transmitting, without disrupting the transmit frequency or the formation of Morse characters. Some radios severely hose CW if you fiddle with front panel controls while transmitting. The K3 is pretty good about this, but not yet perfect. W4NL noted that the TenTec 315 soft-rubber trim rings fit the K3 VFOA knob nicely. They also fit the PowerMate knob, although not quite as snugly; no comment on color choices.
