Elecraft K3 Presets/Settings for JT65B / EME

I checked with WSJT9/JT-65B running the spectraJT waterfall:
I have no Rx EQ set up. TX EQ for SSB is -16, -16, -9, 0, 0,+3,+6,+6 With USB I have display 500-Hz to 2800-Hz With DATA I have display for 900-Hz to 3400-Hz with no TX EQ: USB displays 250-2800 Hz DATA displays 250-3400 Hz From this it appears TX EQ affects the audio passband in DATA., as well as, SSB. Cutting off the low freq below 900-Hz is a disadvantage for JT-65. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?

AFSK A shifts the passband to center on the MARK/SPACE tones as defined by the MARK frequency - i.e., FC = (MARK+SPACE)/2 At 900-3400 Hz your FC is close to 2210 Hz which is FC for MARK=2125. 73, ...

OK, thanks. I had not altered DATA-MD since the radio arrived from
Elecraft. I guess that was set-up default for AFSK A. I also note that I found the WIDTH control was narrowed to 45bps in LSB, so I opened it up as high as 4-KHz. There is still roll off below 200-Hz. That is fine for me as I find some harmonics of 60-Hz below this so its good to reject the bottom 200-Hz. My FT-847 exhibits the same LF roll-off when connected thru my HB soundcard I/F, yet strong eme signals can still be seen below that. With FL1 selected (13-KHz) and WIDTH adjusted to 4-KHz, and DATA MD showing DATA-A USB, I get 200-3550 Hz display in spectraJT waterfall (JT-65B). If I switch to FL2 (2.8-KHz rooofing filter) it narrows down to 250-2800 Hz. But the fun is that the K3 does not remember my settings as soon as I select another frequency from memory (it puts DATA-A back into 45Bps AFSK A LSB). So now I will have to figure out how to get the K3 to remember my settings, or forget using the K3 Freq Memory Editor for programming the K3 memories. I do not see anywhere in the Memory Editor for setting up DATA MD. I went thru my digital channels and DATA-A is randomly either DATA-A USB or DATA-A AFSK LSB. 73, Ed At 01:44 PM 8/13/2011, Joe Subich, W4TV wrote: > > From this it appears TX EQ affects the audio passband in DATA., as > > well as, SSB. > > >No, from that it appears that you have DATA configured for AFSK A and >not DATA A.

I believe I am running 4.33 (what shows in CONFIG).
What we want for WSJT modes is full bw, totally flat freq. response. If I could get 13-KHz it would be great for JT-65 but it appears the K3 DSP limits audio out to about 4-KHz except in AM or FM modes (which are useless for soundcard programs). --------------------- BTW no one has answered my question how to set DATA-A modes when using the K3 Memory Editor. I seem to get random settings when I chose DATA-A with the Editor. I want it to default to DATA-A USB for use of most soundcard sw. I can manually change this with DATA MD key but the change is not saved and it reverts to whatever Memory Editor chose if I change frequency by selecting memory channels. 73, Ed - KL7UW At 06:30 AM 8/15/2011, you wrote: >To Ed... > >Ed, what is your firmware version?

Ed,
If I remember correctly, when a DATA mode frequency memory is stored in the K3 the data sub-mode is remembered as part of the information stored at the time the memory is created. For example, if your K3 data sub-mode happened to be AFSK-A at the time the memory was stored, I believe the sub-mode will be restored to AFSK-A every time you recall that memory. If this is correct, the way to get it to remember the DATA-A sub-mode would be to delete your existing DATA mode memories and re-create them from scratch with the radio in DATA-A sub-mode. As I understand it, the K3's audio output is cut off at 4.2 kHz in all modes, including AM and FM, regardless of which IF filter is selected. Assuming no EQ is applied (EQ is disabled in DATA modes), the output audio response will be nominally flat between approx. 200 Hz and 4.2 kHz, subject to IF filtering and the SHIFT and WIDTH DSP control settings. If your widest IF filter is 2.8 kHz, then your maximum nominally flat audio bw in SSB-based modes (including DATA-A as well as USB) will be 2.8 kHz, although you can use the SHIFT control to shift the audio passband within the overall 0.2 - 4.2 kHz audio window. Note also that even if you have a wider IF filter that is enabled in DATA modes, the wider bandwidth it provides will only apply during receive - your transmit bandwidth will still be limited by the 2.7 or 2.8 kHz transmit IF filter. 73, Rich VE3KI Ed KL7UW wrote: > What we want for WSJT modes is full bw, totally flat freq. > response.

I don't understand why you want 13 kHz for JT65.
The system requirements from their webpage are System Requirements • SSB transceiver and antenna for one or more VHF/UHF bands • Computer running the Microsoft Windows, Linux, or FreeBSD operating system • 800 MHz or faster CPU and 128 MB of available RAM • Monitor with at least 800 x 600 resolution (more is better) • Sound card supported by your operating system • Computer-to-radio interface using a serial port to key your PTT line. Linux and FreeBSD versions can also use a parallel port. • Audio connections between transceiver and sound card • A means for synchronizing your computer clock to UT None of this even remotely indicates 13 kHz needed for operation. The signal seems to be only 400-500 Hz wide. So if anything it indicates that the data A mode on a K3 should be ideal. Using a 6 kHz filter for SSB would give you 4.5 kHz bandwidth on a K3, or eight to ten signals. What gives? 4.39 is the current production.

The width of that window is displayed on the JT-65 screen; it's only 2 khz wide, and in my experience just about all the signals appear within +/- 500 khz of the center. The standard 2.7 filter is plenty.

Rich,
Thanks for the explanation for setting DATA-A. I will try that. It is strange that some frequencies have AFSK-A while others have USB under DATA-A? But I will not waste effort trying to understand how that happened. I want the wide-band submode for every instance of DATA-A. So I will take my saved editor file and delete all the DATA-A Channels and write that to the K3, then ensure that DATA MD is properly set, fill the memories back in that I want DATA-A. That is about 15 channels. Regarding the limit of audio bandwidth...sigh! I ordered two 13-KHz filters for both receivers in anticipation that it would pass the full bw in SSB if the filter was programmed for that. I did not anticipate that it would be limited in audio stages. I did not need to receive FM in both receivers so that was wasted expense since bw can be opened to 4.2 KHz with the 2.8 KHz filter. Of course, I have added two LP-Pan to the K3 main and sub receivers that passes full bw of the first IF before the roofing filters, so I can accomplish what I want to do which is to run MAP-65 at 96-KHz bw. Running MAP-65 from the K3 audio using a soundcard would only allow 4-KHz to be sampled and not really worth doing. Of course JT-65, WSPR, and other programs in the WSJT suite can be run on ordinary audio thru a soundcard. It looks like running any external sw with the K3 will require adding a SDR to the 1st IF (LP-Pan, SDR-IQ, soft-rock, etc.). The P3 is expected to permit exporting I-Q data at some future time so those acquiring the P3 will eventually be able to run external sw, as well. One of the most powerful programs for working weak-signals is Linrad, but it requires I-Q input. http://www.kl7uw.com/LINRAD.htm ------------------------------ Message: 13 Date: Mon, 15 Aug 2011 15:02:52 -0400 From: "Richard Ferch" <[hidden email]> Subject: Re: [Elecraft] Elecraft K3 Presets/Settings for JT65B / EME To: [hidden email] Message-ID: <[hidden email]> Content-Type: text/plain;charset=iso-8859-1 Ed, If I remember correctly, when a DATA mode frequency memory is stored in the K3 the data sub-mode is remembered as part of the information stored at the time the memory is created.
