Nice waterfall Ralf! Several dB better that my reception with a Patch antenna. But not sufficient for 10500 bauds transmissions decoding, I suppose (based on my experience with a 60 cm dish) ?

 

With the Patch, I saw (or to be honest, let’s say “guess”) 10500 bauds transmissions very very weak.

Looks like that I'm in a not bad position for L-Band decoding now. This is my waterfall since a few weeks.
10 x 600 bauds and 1 x 1200 bauds. The dish of 60 cm is in my room at the first floor in the moment. Not outside, like last year.
I see some 10500 bauds also, but very weak.
Decoding with Multipsk Test Version 3, direct connected to my NooElec NESDR SMArTee XTR SDR works perfect.  
With NooElec Low Noise Amplifier (LNA) and Saw-Filter-Modul for outernet and inmarsat.

Hi Ralf I see you are using NooElec NESDR SMArTee XTR SDR mine does not work on normal I get something on i or q but even thats not right but at least it starts Im on W10 tried usb drivers a load of times and still think it is pulling the wrong driver one google said got it going using tcp mine refuses 1234 address 73 Gerry

Thanks, Gerry !

Re the A154 patch - they simply mislead people - I did not know - before buying and now querying to them

that one can use the A154 only with its own cable - 5m long - and that it does not "tolerate" any extension cable !

Nor did I know that they simply prefer not to test it with the current dongles Airspy, Funcube, RTL SDR V.3 etc.

It seems that the only "right" place to use the A154 is the roof of your car far far away from any interferences !

Inbuilt protection against the most common forms of interferences seems to lack altogether !

Probably much too expensive for this surely made in China crap !

I will return my A154s to them for a refund !

Cheers

Re: Bias Tee for C- & L-Band AERO decoding #aero

Hello Chris,

 

>I am particularly intrigued by your comment that you receive 1200 bps signals.

I don’t know how many 600 and 1200 bauds there were, coming from the 3F2 satellite. But here is what I received (with a Patch antenna) on a 48 KHz bandwidth (SDR spectrum). The thin ones are 600 bauds and the others 1200 bauds.

 

 

Yes it seems to have big differences between satellites and particularly relatively to the power: I had not been able to monitor 4A-F4 transmissions which were very weak, whereas the transmissions from 3F2 were OK.

Patrick

Hi Patrick,

I do not use VRS, but I note that Pauk has already given you the benefit of his expertise on this software.
Your other comments make perfect sense.  One of the disadvantages of NOT using a dish is that the antenna is not very directional and is subject to interference from other RF sources.  I live about 2km away from a mountain on which all of Brisbane's TV antennas are mounted plus a host of others 5G antennas, microwave links etc.  The harmonics, sub-harmonics and mix components of these transmissions, which run into 100's of kWs some times cause havoc even at times to the C-Band signal on the dish.
Your comments underline that it is impossible to make definitive statements based on ones own experience.  Reception conditions vary from satellite to satellite.  I am particularly intrigued by your comment that you receive 1200 bps signals.  On 4F1 there is only one 1200bps signal (that I can find), but lots of channels on 10500 bps and 600bps.

Hello to all,
 
In my small experience in L band, I could receive 600 and 1200 bauds transmissions with a 60 cm dish (+ helix antenna) or a Patch antenna, but no 10500 bauds transmissions. For theses last ones, I needed a 1 m dish  (+ helix antenna).
 
With my RTL-SDR V3, the LNA (+ 1500/1550 MHz filter) was indispensable (without it, I had no reception at all).

Re: Bias Tee for C- & L-Band AERO decoding #aero

Hi Chris,

Regarding 1200bps channels on L-Band, on the 3F5 satellite at 54degW I have found 4 containing useful data, a couple of them interest me as they contain transmissions from the USAF C5 Galaxy aircraft, one of the few military aircraft that use 1200bps. In addition I've found six 600bps and three 10500bps channels. Most military traffic confined to the slower bit rate

My findings are the same as Patrick, only the 600 and 1200 bps can be received without a dish (using a patch or small helix) so I usually use a dish for all L-band and C-band reception

Cheers,

Paul

Your other comments make perfect sense.  One of the disadvantages ofNOT using a dish is that the antenna is not very directional and issubject to interference from other RF sources.  I live about 2kmaway from a mountain on which all of Brisbane's TV antennas are mountedplus a host of others 5G antennas, microwave links etc.  Theharmonics, sub-harmonics and mix components of these transmissions, whichrun into 100's of kWs some times cause havoc even at times to the C-Bandsignal on the dish.
Your comments underline that it is impossible to make definitivestatements based on ones own experience.  Reception conditions varyfrom satellite to satellite.  I am particularly intrigued by yourcomment that you receive 1200 bps signals.  On 4F1 there is only one1200bps signal (that I can find), but lots of channels on 10500 bps and600bps.

Hello to all,
 
In my small experience in L band, I could receive 600 and 1200 bauds transmissions with a 60 cm dish (+ helix antenna) or a Patch antenna, but no 10500 bauds transmissions. For theses last ones, I needed a 1 m dish  (+ helix antenna).
 
With my RTL-SDR V3, the LNA (+ 1500/1550 MHz filter) was indispensable (without it, I had no reception at all).

Hi Patrick,

 

I assume you have VRS setup and working so I'll just describe how to add a feed from Jaero

 

In Jaero tick the "enable Basestation Format" and choose the address and port, if Jaero and VRS are on the same computer it will be 127.0.0.1:30001  ( I use ports 30001 to 30009)

 

In VRS under Tools/options select receivers and add new receiver- in the box that opens give it a unique name (say "jaero-1") , choose format  :Basestation , connection type normal - in the address and port box enter the details as entered in Jaero.

 

That should be it, go back to the receivers (under tools/options) and select jaero-1 as the web site receiver.

 

In my case I have several instances of Jaero working each feeding a different port, within VRS I create a merged feed for all the individual feeds and select this merged feed for web site display.

 

Hope I haven't missed anything

 

Cheers

 

Paul

I would like to send plane positions to Virtual Radar, but I have not found on Internet a clear way on “how to send plane positions”.

So for the ones using Jaero and Virtual Radar (mainly Paul and Chris), could you precise which control (in the settings panel of Jaero) do you tick (notch) to obtain from Jaero that it sends plane positions to Virtual Radar. It will give me an indication. TKS!

Hello Patrick,

I think in Jaero it should be the section "ADS data output" and "Enable BaseStation Format" which sends feeds in BaseStation Format on port 30003 to VRS

Multipsk not working after a Windows 10 update (no more sound card seen) - SOLUTION

Patrick Lindecker
 

Hello Mike,

 

>In W10 settings, privacy, allow apps to use mic. Switching this setting to On allowed Multipsk to open and operate normally again.

Thanks for the solution. It is a pity that Windows update changes this type of setting and makes life complicated!

Hi,

This is an update on the line in socket problem I had see below.

Last night in FT8 group on FB I found out how to solve it.

In W10 settings, privacy, allow apps to use mic. Switching this setting to On allowed Multipsk to open and operate normally again.

I assume all my other software which uses line-in eg Audacity must also be working again too.

Mike.

Hi,

After a recent W10 update my line in socket will not work. I am getting this message on opening Multipsk...

"Error Multipsk cannot function because the Line in of the sound card is in use by another program".

All other software that uses Line in won't work either eg Audacity.

I have re-installed the sound card drivers from manufacturs website - still no joy.

My system is W10 on HP Envy 700 PC.

Beats audio is working in my case its only the line in that wont function.

Regards,

Mike.

Hi Patrick and all:

Microsoft has confirmed in one of its forums that with the latest update of Windows 10, some users do not
work the sound.

 

Windows 10 audio stops working after installing Intel Smart Sound Technology driver (version 09.21.00.3755)

Hello,

 

Just to give a feed back about a problem that I have had today. It occurred that I freed the W10 PC for some room (it’s an hybrid with little room), so that Windows determines that there was enough room to make its update. I leave Windows make its update. After this update, I discovered that Multipsk could not work because it does not see any sound card. Moreover the “loudspeaker” icon appeared with a dot to show that the sound card was not available.

 

When I decided to see what it happened, I changed of mouse (the previous one was slow) and miracle, after changing of mouse, the sound  card reappeared.

 

I am not sure why a research of the USB driver for the new mouse makes the sound card to be recognized, but it’s what I noted.
