Hi Domenico and all,

Here is already one problem discovered, but that doesn't have anything to do with WSQ itself:

It's the media player (VLC) which I used to play back your recording.
Here, the recording is analysed by two decoders (with slightly different settings) running side-by-side. In the spectrogram near 1100 Hz you can see how the constant-frequency "carrier" (local or distant QRM, I don't know) suddenly makes a "S-curve" because the player slightly changes its resampling ratio. No suprise the result from the recording is worse than during our QSO:




Will be interesting to compare this with a built-in wave file analyser, which I will now integrate in WSQ .

At least the 'bent worms' will turn into thin vertical lines again ;o)

About improving the core decoder algorithm : A bit too early. First I need to understand how every bit and piece in it works...

Ok Wolf.

Thanks to you for the test and for your efforts on improving WSQ. I'm shure you will fix it.

Let me know if you need further helps.

Again tu and have good w.e.

Good night to all.

Hi Domenico,

Thanks for the WSQ QSO and for testing.
Signal just went down below the "red line" which is nice for testing.
I have a lot of recordings now which I can play into the decoder, over and over again.

Yes, I can imagine !

Ok ... But that may be a problem with the sampling rate. I had the same problem with Rik recently, using the original software both ends.

Hi Wolf,  all

Ok i can be qrv WSQ on dial 477. 3 kHz within 15 min. Is it ok?

Thanks

Greetings all,

If someone else is going to try WSQ tonight or tomorrow, please announce
here, including the frequency - ideally an hour before starting.
I'd like to make a few audio recordings with 'real on-air signals' with
greatly different SNRs, for software testing.
