Re: HELP WITH VDL2

Derek Henderson
 

Hi Patrick I have read your instructions  ( I did consult the Manual  on the subject )  I have never used VAC software at all and do not know anything about it
even though I have heard of it. The bandwidth of my receiver is quoted as greater than 2.2khz and I use a CSL USB Soundcard with standard 3.5 interlinks
from radio headphone skt to MIC/ Headphone Skt on my laptop Perhaps from what you say it may be better for me to use an SDR receiver for VDL2?
As cannot work out how the connection from radio to laptop would work using VAC software Maybe I have gone beyond my limits on this one ???

So thank you for your reply Have a nice Christmas

Rgds Derek henderson.

Hello Derek,

 

Here are the conditions for reception with a receiver (from the manual):

Reception in USB either on a standard (non SdR) receiver, or on a SdR managed by a SdR program connected to Multipsk by a VAC
Multipsk waits for an USB signal located at 12 KHz of the central VDL2 frequency, so the user must adjust his receiver in USB on a frequency of 136963 KHz (136.963 MHz). The VAC link must be done at 48 KHz (Ksamples/s). If all is correct, the VDL2 transmission on 20 KHz minimum (not filtered ideally) must be transmitted entirely by the VAC link. The "Direct interface through the sound card" button must not be clicked. The VDL2 messages will appear (before, leave the "I/UI", "XID" and "RR..." buttons in pushed position). Sames advices about the shift ("Go:" button) et about the numbers after "D:" as the ones given above, excepted that the shift compensation will be, here, applied directly to the receiver.

Is your receiver able to directly supply such signal (i.e. with a bandwidth  of 20 KHz minimum)?

Good morning to all The receiver I am using is an Icom RS 8500 coupled to 
Diamond D 333 for air band and  Wellbrooke 1530 loop for HF 

And thanks to Paul and Dick for their replys and advice

Hello Derek,

What receiver do you use? In direct interface with Multipsk or no (i.e via a VAC)?

For a SDR play, see the demo of Mauro:
https://www.youtube.com/watch?v=XKzMONAXAaU (use of Multipsk to decode VDL2 with a SDR-Play receiver)

You have also this demo (in French): https://www.youtube.com/watch?v=6Bhbgs0pjxo
You will see how look like VDL2 frames on the SDR window.

Derek,

If you're using an external software/radio for the receiving (like SDR Console) you have to set the frequency 12Khz below the nominal/published frequency. So for 136.875MHz set the receiver to 136.863MHz.

See the help file for details

Hello Patrick

oki-doki, thanks for info. So I will have to do it manually.

Re: MultiPSK timestamp setting

Hello Andy,

 

RR for all. No it is not possible. The time of decoding is taken from the PC clock.

Note that several (and rare) modes transmit the time information, so in their case there is no such problem.

Hello all

I was playing with my Elad and the SDR V3 Console. I made a few minutes record and took this as playback 

with MultiPSK. Example here was 2187,5 kHz DSC. All running fine.

But MultiPSK take the time from my PC during the decoding but this is of course not the time of the reception.

Original reception:  1156 UTC - playback decoding was half an hour later and so the decoding says 12:26 in the timestamp.

So how can I say MultiPSK, that it should take the time from the recorded I/O stream? Possible?

Please look attached picture.

Hello Joe,

 

rsp_tcp.exe is part of the Multipsk package (at least the last one). So it is located in your Multipsk folder.

Thanks to everyone for the helpful information. I tried to run "rsp_tcp.exe" from within the SDRuno folder, however the file is not there. Do I need to download from somewhere?

Thanks Paul! Appreciate it! Thanks to everyone for the helpful information!

Joe,

I think you'll find it here, you may have to scroll down a bit - I don't have it in my SDRUno folder either.

Hello Joe,

 

With RSP1 it works always well (as far as I know). If your SDRplay is a RSP2 (is it?) it seems that some problem occurs in the connection from time to time. For a RSP2, the solution is the one suggested by Fred.

Appologies if this has been discussed previous but when I try to launch SDRplay from within MultiPSK I receive the message "Failure of the TCP/IP connection, the SDRplay receiver is probably not connected.Disconnecting error. Socket Error n°10053 : Software caused the connection to abort. A connection that has been made was aborted, usually due to connection or protocol error.TCP" Does anyone have any recommendations on how to get the SDR to work?

Re: SDRPlay and Multipsk

Fred Albertson
 

HI Joe,

Close MultiPSK.

Make sure that SDRUno, or any other program using the RSP,
is closed.

Go to the SDRPlay/SDRUno subdirectory, and run the program "rsp_tcp.exe".

Reopen MultiPSK, and click the RSP button.  It should work.

Hope this helps,

Fred

Hi Mike,

Yes your right about  Win 10 updates and driver updates..

Most of my issues have been solved and in reality have been using 8 year old laptop and upgraded to Win 10 from Win 7 and there is some residue left over..
It was never a  clean install and  upgraded with a CD Win 10 upgrade. .For some reason Win 10 sees my Winradio Virtual Sound Card as a sound source...even if I am not using Winradio..which is probably right..
Saying goes....if aint broke don't fix it)

Touch wood as of today have sorted sound out and with a new Samsung 500gb SSD Drive is very very fast)

Re: MultiPSK and Windows

Hi Steve,

I still don't think there is any problem with Windows 10 sound. I have checked the Windows logs and I have had 10 updates to Windows 10 in the past 6 months and have never had any problems with the sound. My sound card is the built in Realtek sound system on the MSI motherboard.

So maybe there is a problem with some sound card drivers rather than a Windows problem, could it be that some sound card drivers are not updated regularly? Or the user is not keeping their drivers updated? Realtek certainly appear to release updated drivers fairly regularly.

Hi Peter,

Nope your not missing anything......the original heading of Multipsk Unusable was / is  very unfortunate and not true...
Updated from Win 7 to Win 10 and have many sound issues..
Every time Win 10 gets updated....some very stable programs seem to have issues including sound.....your not alone).
