Re: Frequency Control while ISS passing

Hello Ralf,

 

>But I had to control the frequency manually

If you click on the "afc" button (on the Multipsk SdR window), it will be done automatically.

 

>I wonder a bit about your given frequency of 144.800 for SSTV. As I know it has to be 145.800?
Yes you are right it is 145.800!

 

>1. The frequency control between Multipsk and my transceiver works now without an active pass of the ISS. Is this correct? As I know from the other modes, it only starts if a pass over my QTH is in visible
No it’s a bug. I will fix this.

 

>The control for doppler differ a bit from Orbitron. 
Yes surely. There is small chance to have the exact same calculations (and moreover at 14100 km, for which the Doppler has no real meaning). My physical model is rather simplified.

Hello Patrick and all,

I was able also to manage a few pictures this morning. So, in the main it works. But I had to control the frequency manually and my hope was, that this should be done by Multipsk. Especially with the time of the current passes of the iss over europe :-)
I will give it a new try tomorrow morning as unattend reception.
My configuration: Diamond X30 --Yaesu 991A--Commander--Multipsk

Tnx Patrick for the clarification about the reception. 

I wonder a bit about your given frequency of 144.800 for SSTV. As I know it has to be 145.800?
I changed the entry in the textfile.

Here are 2 of my received pictures from this morning at 0845 UTC.

DigiKeyer II microham & multipsk

GM
I am encountering compatibility problems between multipsk and digikeyer ham II. The tx goes into transmission but without a dial tone. In addition, the drivers of October 9, 2020 do not seem to be correctly seen by w10.
Do you encounter any problems and how did you solve them?
Thanks for your help

Hi Patrick,

concerning the slant, problem solved, tks!!

What you think about this result ? ..color is missing, picture is “dobled”..

Any suggestions ? many tks in advanced to all !!

Good Morning!

These are the results of standalone working this morning:

And although the ISS isn't visible the 1. button contains the frequency and the control is still working:

Good morning Patrick,
 
I have the SDRplay RSPdx directly controlled with Multipsk (I/Q direct interface via the sound card). It is important to select 25 kHz FM.

I used a sdrplay rsp1a controlled from multipsk.
Most pics were just picked up auto but the last one I was around to adjust.
Using my roof mounted base station dual band antenna with a sma adapter to the rsp1a.

Re: Frequency Control while ISS passing

Just did the setup for the next morning pass for standalone working. Two things I see now:
1. The frequency control between Multipsk and my transceiver works now without an active pass of the ISS. Is this correct? As I know from the other modes, it only starts if a pass over my QTH is in visible
2. The control for doppler differ a bit from Orbitron.

Hi Joe,

Can you email me direct to

with screen print of the whole screen at time you get this error message. I need to see everything to make sure I understand where you are getting this error.

Thanks Mike, downloaded the software, great program! The only issue is that I keep getting a pop up box that says error path/file access error. Any ideas on what could be causing this?


Re: Frequency Control while ISS passing

Josef,

 

I forgot to ask you about your configuration. Do you use Multipsk in direct interface with the RSPdx (Multispk doing the FM demodulation) or do you use SDRuno (SDRuno doing the FM demodulation) and a VAC towards Multipsk?

Thanks for the pictures Tim, the last one is good.

Do you record them in automatic (stand alone worhing)? From Multipsk in SdR or from a FM receiver?

Re: Frequency Control while ISS passing

Patrick Lindecker
 

Ralf,

 

Erratum about the FM demodulation (from the manual):

Specificities of SSTV (PD120 or PD180 format) pictures received from the ISS station

It is necessary, at first, to demodulate the FM transmission to be able, afterwards, to decode the SSTV transmission.

FM demodulation (on SdR receiver)

The FM demodulation can be done either by a FM demodulator program connected to Multipsk through a virtual sound card or directly by Multipsk (best solution).
To make Multipsk demodulates FM, click on the button corresponding to your SdR receiver ("FunCube" for exemple), or otherwise on the "Direct interface through the sound card" button. It will be opened a SdR window called "I/Q direct interface via the sound card, for SdR transceivers".

Select the appropriate frequency and gain (maximum, a priori) after having pushed the "Transceiver" button.

For SSTV transmitted by the ISS station, the "FM 25 KHz" option must be selected. When the ISS station is passing over your position, center, on the "SdR" waterfall, the reception on the SSTV transmission, then push the "afc" button. Do in such way that the signal be centered on the SdR waterfall (towards 0 Hz).
SSTV picture must appear.

The displayed "Global level" on the "I/Q direct interface" panel must be sufficient (at least 10 %). Increase the SdR gain if necessary.

To know the pass time over your position or to make the reception automatic, start the Satellites tracking function (see below).

Hello Ralf,

 

I forgot to update the SATELLITES_FREQUENCIES.TXT file with the ISS. Here is, attached, the new file to save in your Multipsk directory.

Once the satellite visible, the frequency of 144.800 MHz will show on the first button.

 

Tell me if it works. It will be interesting for everyone to see your pictures in PD120 or 180…

 

Note: these transmissions must be received in FM: perhaps “FM x KHz” with 4 KHz adjusted on the “I/Q direct interface…”?
