Attempted to setup DSTAR simplex mode today but it acts like the ThumbDV dongle isn't working correctly. Followed the directions precisely according to the D-Star How To Guide. The fellow on the other end saw my Call Sign one time out of many attempts but never any audio. His panadapter (and mine) showed a short burst of the expected TX pattern followed by a narrow carrier signal at the center frequency during PTT. When He Transmits I occasionally see his Call Sign come through and a reasonable looking panadapter and waterfall presentation but no audio. We both tested with and without amplifiers and in normal sideband, audio and signal strength was very good . I stuck the Thumb DV into my PC and it loaded drivers and said the ThumbDV was ready to use. Put it back in my 6500 and same as before. Used software versions 1.9.13.23 and 1.10.15 Beta with same results. Power cycled, uninstalled and reinstalled waveforms with no change. I also have a 6300 which I'm about to try but the 6500 is D-Star challenged. Has anyone seen anything like this?

If you tried to revert back to 1.9.13 SSDR software did you also uninstall the latest D-STAR Waveform and revert back to the earlier D-STAR Waveform program? Maybe Flex can confirm this but I believe the latest D-STAR waveform is only compatible with the Beta SSDR software?

There is only one SmartSDR D-Star Installer in the Waveform Download section and I did re-install it under both 1.9.13 and 1.10.15.

Thanks Tim. As a note I get exactly the same results on my 6300. I suspect the ThumbDV may not be working. I got it with my 6300 back last spring but I never tried it until my 6500 arrived. Two of the guys I've been working with (N3WZU and N3CAL) have made QSO on D-star using their 6500's with the latest version 1.10.15 but they can't hear me and I can't hear them even with 20 over signal. I get no digital signal on the panadapter when I TX. Only a spike at center frequency. In RX I get a good digital pattern on the panadapter but no decoded audio. So it looks like the THUMBDV is not encoding audio for TX because there is no digital pattern in the panadapter and even though there is a pattern in RX it isn't decoding audio. Got a spare ThumbDV?

I did purchase the Thumb DV from FLEX and have written a HelpDesk ticket #16646 and Dudley and I have been exchanging messages for about two weeks. What is my next step? Order Number:: AB-9322. I did not have the opportunity to use it until I got my DEMI 70cm transverter.
Thanks

We switched to FreeDV waveform and decode was about 95 to 99%. It's just structure of the codec between FreeDV and Dstar. There not much you do about Dstar as it was developed a long time ago and requires a very solid unwavering signal do to the pour error correction built in the codec.

I've found that you need a 10 db over s-9 to get solid copy on HF DStar, and QSB effects it very badly, FreeDV is much better on HF for getting the voice through, but DStar sounds better but takes a lot of frequency spread, 6 KHz verses 1600 Hz on FreeDV .
