DATA A mode and WSJT-X
Locked
 
|
I tried JT65 for the first time today (there is a first for everything,
right?), and to my surprise, I discovered that for some reason, the DATA mode is not usable on that program! Not 100% sure the mailing-list allows images in emails, so I will try to describe the issue as clearly as possible: - In USB mode, with a flat EQ, I get a flat spectrum apart from the actual JT9/JT65 chirps, from 200Hz to 3000 Hz - In DATA A mode, on the other hand, I get a peak around 100Hz, nothing until 300Hz, then a huge noise peak raising from 300Hz, peaking at 500hz and going slowly down to 1kHz. Then a big dip in signal/noise centered around 2kHz. In other words, very distorted signal! Image speaks for itself: http://imgur.com/QyqpzEh I am pretty sure this does not come from the radio, with a simple audio waterfall displaying at the same time in another program I don't see this artifact, but I wonder if anyone else has seen this and can explain it? Could it be an FFT artifact linked to the sampling rate of the soundcard and an internal sampling rate of the radio in DATA mode? Something else ?? Kind of scratching my head on this one, maybe smarter/more experience Hams on the list will have an answer! Oh yes: WSJT-X is running on a Mac, not that it should really matter. 73 de Ed, W6ELA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

A quick guess. The DSP bandwidth for Data A is separate than
from USB. Try adjusting the HI and LOW cut knobs on your radio. (I'm assuming a K3 or KX3.) I have used my K3 for digital modes, JT, PSK etc. using WSJT-X, cocoaModem, and fldigi. There's a bit of a learning curve with all these programs, but it isn't too steep, and it's a computer after all. :-) 73 Bill AE6JV On 1/23/15 at 8:51 PM, [hidden email] (Edouard Lafargue) wrote: >I tried JT65 for the first time today (there is a first for everything, >right?), and to my surprise, I discovered that for some reason, the DATA >mode is not usable on that program! > >Not 100% sure the mailing-list allows images in emails, so I will try to >describe the issue as clearly as possible: > >- In USB mode, with a flat EQ, I get a flat spectrum apart from the >actual JT9/JT65 chirps, from 200Hz to 3000 Hz >- In DATA A mode, on the other hand, I get a peak around 100Hz, nothing >until 300Hz, then a huge noise peak raising from 300Hz, peaking at 500hz >and going slowly down to 1kHz.

Yep, there is always a first time for any mode. I remember when PSK31
was introduced and I tried it. Had a problem similar to yours, but on a FT101EE at that time. I've used JT65 on my K3 many times, with DATA A as the mode. I can assure you that it works fine. But that is here, and with a different configuration (well, probably). The spectrum you posted was a surprise. You should be seeing tones between 1270 and 1953 Hz, and they would show as discrete "blips". The spectrum shown is not at all like that. I'd be scratching my head too, Ed. It may be something simple, and probably is. I'll think about it a bit though. Maybe others will consider this as well. It's a little perplexing. Which Elecraft transceiver are you using? Both the K3 and KX3 support DATA A modes. 73, matt W6NIA On Fri, 23 Jan 2015 20:51:23 -0800, you wrote: >I tried JT65 for the first time today (there is a first for everything, >right?), and to my surprise, I discovered that for some reason, the DATA >mode is not usable on that program! > > Not 100% sure the mailing-list allows images in emails, so I will try to >describe the issue as clearly as possible: > > - In USB mode, with a flat EQ, I get a flat spectrum apart from the >actual JT9/JT65 chirps, from 200Hz to 3000 Hz > - In DATA A mode, on the other hand, I get a peak around 100Hz, nothing >until 300Hz, then a huge noise peak raising from 300Hz, peaking at 500hz >and going slowly down to 1kHz.

Oh yes, I kind of forgot the most obvious :) It is KX3, running on a beta
firmware (2.33, not sure it is released yet). The only difference between the two sections of the screenshot are USB and DATA A mode, nothing else changed. Very strange. The "Flatten" checkbox is checked, I will try with the checkbox unchecked tomorrow morning and report. On other programs like fldigi, the only difference between USB and DATA A (both with widest possible filter bandwidth) is a cutoff at 500Hz on DATA A whereas USB goes a bit lower.

Be sure to keep your audio input (RX) as low as you can. Your pic could be a result of high audio levels.
On my K3, I set LIN OUT at 1, then set the driver level just high enough to allow decoding (3/100 in the Windows driver). Overdriving causes myriad issues, mostly causing the decoding to fail or work poorly and it will FUBAR the waterfall. You do NOT want to tickle the sound card AGC, ever, if you want to watch multiple conversations. That's difficult to manage. If one signal is substantially blocking the signal you want (hitting the AGC, lowering the apparent level to other Q's), adjust the Hi/Lo cut (and center freq) to filter it out. This is effective in any digital mode. A P3 or a good waterfall display helps in this. Any sound device 'feature' should be disabled (shaping, boost, bandpass etc.). Otherwise it only mucks with the decoder. The K(X)3 in Data A mode gives flat audio; exactly what the decoder wants to see; allowing it the best chance of performing well. 73, Rick wa6nhc Tiny iPhone 5 keypad, typos are inevitable > On Jan 23, 2015, at 9:54 PM, Edouard Lafargue <[hidden email]> wrote: > > Oh yes, I kind of forgot the most obvious :) It is KX3, running on a beta > firmware (2.33, not sure it is released yet). > > The only difference between the two sections of the screenshot are USB > and DATA A mode, nothing else changed.

I can duplicate the same effect here with my K3 uncheck the Flatten
box at the bottom of the waterfall Flatten is for rigs that tend to have a hump in the middle of the audio but with K3/KX3 which are flat to start this feature will have a negative effect Flatten on http://i.imgur.com/eFN20vG.jpg Flatten off http://i.imgur.com/cpQoPEX.jpg David Moes President: Peterborough Amateur Radio Club.

WSJT-X works very well with K3 and KX3 set for Digital A. As others have noted, we need to set the bandwidth per mode. I don't know how to interpret the image you posted -- there's too little time on the waterfall, and no amplitude display. This almost looks like the sort of problem that could be from a miswired cable, or from not having equipment bonded together properly. You should be using the Line Input of the K3. When the Line Input is selected, the Mic Gain knob acts as Line Input Gain. See http://k9yc.com/GroundingAndAudio.pdf for detailed advice on Grounding, Bonding and Audio Interfacing. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Thanks everyone for your super valuable input! "Flatten" it was. Very
strange how much difference checking this box makes when just moving from USB to DATA without touching anything else! I'll dig deeper in the documentation to understand what's behind this setting, thanks for pointing it out to me. And you are right, I need to set soundcard input super low and AF fairly low to get a nice clean signal on WSJT. I'll be careful not to get hooked too much on J65 - I do like the ragchew aspect of PSK31, and JT modes will definitely not let me do this, that will help. But just monitoring is great fun.

Re: DATA A mode and WSJT-X

|
I have not played much with WSJT-X (I have been using JT65 Comfort)
But as I recall the display did have a slope to it and there was a check-box that did flatten it. One thing I did was to make a JT65 Macro that set my filter bandwidth =============================================================================== JT65 - 2.2KHz Bandwidth=============================================================================== MD6;DT0;BW0220;IS 1250;------------------------------------------------------------------------------- MD6; = Set Mode to "DATA" DT0; = Data Mode to "DATA A" BW0220; = Bandwidth to 2.2KHz IS 1250; = IF Shift Center Frequency 1.25KHz (Must have space in command)=============================================================================== From: Edouard Lafargue <[hidden email]> To: [hidden email] Cc: Elecraft Reflector <[hidden email]> Sent: Saturday, January 24, 2015 2:08 PM Subject: Re: [Elecraft] DATA A mode and WSJT-X Thanks everyone for your super valuable input! "Flatten" it was. Very strange how much difference checking this box makes when just moving from USB to DATA without touching anything else! I'll dig deeper in the documentation to understand what's behind this setting, thanks for pointing it out to me. And you are right, I need to set soundcard input super low and AF fairly low to get a nice clean signal on WSJT. I'll be careful not to get hooked too much on J65 - I do like the ragchew aspect of PSK31, and JT modes will definitely not let me do this, that will help. But just monitoring is great fun.

Too slow. A rate of 12 Q/hour max is unappealing.

But iOS allows to say your typing... Still faster. :-)
I've tried JT modes at flea power and up to a half gallon. Interesting but I still prefer cw and Q rates much higher. No, QRP is also uninteresting to me until I can do better than a stealth dipole and break the 300 country barrier (243 now). 73, Rick wa6nhc Tiny iPhone 5 keypad, typos are inevitable > On Jan 24, 2015, at 3:02 PM, Phil Wheeler <[hidden email]> wrote: > > Yes, for me too, Rick.
