Anyone running TrueTTY with a 6xxx series

I would like to get TrueTTY working with the Flex 6500 and give it a whirl but I don't see TX DAX for sound output on the program. Any programs that DXsoft offers actually.

Anyone using this or CwType?

Hey Rich,

I'm guessing you wouldnt be asking if your setup dialog looked like this:



I've seen some programs that cant see all of the available sound devices.  It's possible that TrueTTY is one of them and I'm just lucky enough to have my DAX devices in the first 10.

I'm still having trouble getting TrueTTY to transmit a signal.  Using OmniRig, it will key the transmitter but I'd rather have it use a SmartSDR CAT PTT port instead.  But even with OmniRig it's trying to transmit outside of the transmit bandpass when in RTTY mode.  But, I'm sure there a setting somewhere to help with that.

Don that's perfect. But I am missing is the Audio TX port you are showing. So I am in the same boat.

Can receive and key transmit but now power.

Once you're able to get TX audio out, in SmartSDR for the slice in RTTY mode, change the Mark to 1600 from 2125 and the signals will line up.  I'm still trying to figure out if this is either the best way or the only way.  Adjusting the transmit Low Cut and High Cut is also necessary 1500 and 2000 is a start.

Nope, not the best way or the only way.  But here's what works for me.

First make the TrueTTY settings look like the screen grab above.  Then, choose the Tuning tab of the settings dialog and make sure 'Tune RIG by' is set to NONE. Back on the main TrueTTY turn AFC off and txAFC on.  With a wide RTTY filter in SmartSDR tune to a signal, then in TrueTTY, click to tune it there.  The status area at the bottom should show 2210hz.  Then, select the setup dialog and save.  Turn off txAFC and turn AFC back on (or adjust as needed), and tighten up your filter in SmartSDR.  I like 400hz. 

So there's no need to change anything in SmartSDR but afterwards, after configuring the way I described, you can tune RTTY from SmarSDR and TrueTTY will stay in sync with it.  While running the trial license you'll have to repeat this procedure each time you start up.  Saving the configuration is an option only available in registered copies.

TrueTTY doesnt appear to have any direct support for N1MM Logger+ or even the features to add dynamic support for any loggers except AALog, another product by the same author.
  
It's interface is uncluttered by unnecessary features and looks well suited for RTTY and digimode QSOs.  I'll stick to N1MM Logger+ for contests but TrueTTY might be what I've been looking for, for causal digimode contacts. 

I've also confirmed that only the first 11 of my audio devices show in the setup menus.  This could be a real problem if the DAX channels you want or need to use (like TX) dont appear on the list.  With luck, the author will address this issue.

Sounds like TrueTTY suffers from the same issue MMTY has where it only shows a limited number of audio devices.

Stu, K6TU, released a patched version of MMTY that allowed hiding the DAX Reserved devices from the list.

Rich, I wrote to the program authors about SeaTTY, CWGet and CWType about the same issue, namely the number of sounds ́cards these programs can recognize. 

They responded very friendly and at once and updated the programs.

You can do the same for TrueTTY.

Thanks for everyone's help and comments. Dropped Sergei an email. Hoping he can address it.

His drop down menu is very limited to choices for audio devices.  Similar to the 90s when we only had two choices :)

The elephant in the room is that TrueTTY is very old in terms of its deciding capabilities. That is, it is far behind 2Tone and GRITTY. So rather than wait for the developer to update the audio source drop down menu, you may want to consider looking at the better alternatives.

CQ WPX RTTY is next weekend. I will be running MMTTY, 2Tone, and GRITTY for full decoding diversity. Works really well and often I wonder how the software prints a perfect copy on my screen when I hear nothing but noise.

Which of the three, MMTTY, 2Tone, and GRITTY, do you feel is the best weak signal decoded?

The answer very much depends on your objectives. As I contested, my goal is to win big, which means I should be aiming for at least 100 QSO/hour and about 200 per hour during the prime hours of the contest. These numbers are of course across both radios (SO2R).

So if the goal is a very high rate then you can’t afford to slow down and ask for repeats. You need all 3 decoders to maximize the likelihood of good copy. All 3 use different algorithms that work better or worse in different conditions. So between two instances of MMTY running two different profiles, 2Tone, and GRITTY, and the built-in decoder there are very few occasions when I repeat is needed.

If I had to pick one and only one, I’d be on the fence between MMTTY and 2Tone. Most hams I have met underestimate MMTTY as they don’t bother with different profiles or DSP settings, especially if the settings are CPU intensive.

On the flip site, 2Tone substitutes the lack of infinite settings with a modern Bayesian statistical analysis based decoder that works amazingly well.

Last but not least, for me personally it is important to transmit FSK, not AFSK, using my microHam MK2R+ SO2R controller; 2Tone can’t do that so I use MMTTY to TX. This of course is totally transparent to me because N1MM handles TXing and I couldn’t care less which engine generates the FSK.

That is fair enough but GRITTY is only decode and does not have the ability to send as far as I know. I would rather not have two more programs to deal with instead of one.

The latest version of TrueTTY (v2.98 beta) no longer limits sound device selection to the first 10.

Must be the BETA version?

I checked both the latest non-beta (v2.95) and the beta (v2.98b).  Of the two, only the beta showed the full list of devices on my systems.

Thanks Don.
