ModeSDeco2 and ModeSMixer2 - console programs for RTLSDR and transcoding

[Anmer]

Were you able to see local aircraft within 5nm using the SBS-3?

What software are you running on the RPi and what receiver and antenna?

Are the aircraft you see on FR24 ADS-B?  Bear in mind that FR24 "predicts" the continuing aircraft track even when the signal is no longer being received.

Hi Anmer

Yes, I could see all local aircraft with the SBS3.  I am running ModesMixer2 with a FlightAware ProStick with RF Amp/1090mhz filter.  The antenna is a DPD ADSB Vertical antenna.

Interestingly a friend had given me a copy of his SD card and it all worked fine, but the Flightaware was set up with his settings/sharer code, so I started from scratch so that I could get my own code, so can only presume that there has been a problem with the software downloaded.

Thanks Mark.

Did you download the PiAware "build"?

Do you see the local aircraft on your Skyview map?

Hi Anmer

The aircraft were also not showing on the Skyview map.   The missing aircraft are up to about 15nm from my location.   Another friend of mine appears to have a similar problem when using the Stretch version of
the software.

I have gone back to using the FlightAware dongle with ModesDeco plugged straight into the USB port of my notebook.   All working fine and all aircraft displaying.   The only thing is I now do not have the advantage of the MLAT aircraft being displayed.

I tend to think that there is an issue with the Stretch/ModeSMixer2 software for now.

Hmmm.  That's strange as the Skyview map takes tha data directly from PiAware. 

There's a new PiAware 3.6.2 image just released for Stretch:

Hello everyone

Ive just finished compiling UK NavAids for Modesdeco2.

I have enclosed 2 files as attachments

1 x file compiled with Notepad ++

1 x file compiled as a normal .txt

Just copy and paste into your configuration file .

I have tested it on my system with only one error which occured but have now corrected it and is all working .

Please let me know if i have missed anything or if any data is outdated and i will update it.

NOTE....

I also have a file which i started several weeks ago with some waypoints for my location in Aberdeen and a couple of navaids for eham .
This file is working, but is a work in progress.

Hope the 2x files i have enclosed are of use to everyone using Modesdeco2 ?

pls keep in my mind a Pi can create much more noise than everyone expect.

pls keep in my mind a Pi can create much more noise than everyone expect.

Can you share any evidence of this?

[Radio2.0]

not now because the Pi are somewhere in a junk box. 
I use an Splitter and everytime when the Pi is firing up the noisefloor gues up extreme

[Anmer]

Strange. There are, I estimate, 30,000 or more people using the RPi with a DVB-T SDR to track Mode-S aircraft.  I have 5 here.

I don't think the RPi is gereating unacceptable noise.  But I could be wrong.

[Radio2.0]

  you can check it by our own.

1) Take an Notebook and an LNA, Dongle + Antenna put it in your room.
2) turn it on and watch the spectrum
3) turn the Pi on and see if anything change.

[Anmer]

If the RPi is generating so much noise, why doesn't it impact adversely on the 1090 MHz data?

[Radio2.0]

how sould you notice it?
