2 years ago Unfortunately I cannot answer any of your questions as I am NOT the author of the software acarsdeco2. It was written by Sergsero and he uploaded the file "acarsdeco2_rpi2-3_debian9_20181201.tgz" to his Google Drive. Interested people used to manually download it from Google drive, manually extract the Linux binary "acarsdeco2" from it and manually run it by command line.
My contribution is to write the automated install script and post it on Github. When run, the script does following:
- Creates folder
/usr/share/ad2 - Downloads file
acarsdeco2_rpi2-3_debian9_20181201.tgzand saves it in folder/usr/share/ad2 - Extracts Linux binary
acarsdeco2from downloaded file - Creates a config file
/usr/share/ad2/ad2.conf - Creates systemd files to automatically start the Linux binary
acarsdeco2using the parameters in file/usr/share/ad2/ad2.conf - Creates a symlink of Linux binary
/usr/share/ad2/acarsdeco2in folder/usr/binso thatacarsdeco2can be manually run from home or any other directory by just typingacarsdeco2and pressing Enter key.

Hi
After the successfull installation on Raspbian 11 64 bit I got to work with your acarsdeco2 software and have a few questions about it.
First question: I would like to have a log of all received messages, if you restart the software all received messages are gone (I suppose they sleep in the RAM?). Can this cause a flooding of the RAM over time? I have this argument: --logfile logs But it does not save any logfile in the subfolder logs. It did not create it either in the ad2 map. Is the saving time dependant? Which format are they?
Second question: I would like to see all messages on the frequencies, both from aircraft and from ground stations (replies). How can I do this?
I suppose I need to invert the no-uplink, no-sq, no-empty as it is already on? It is a bit unclear to me.
--no-uplink Don't display uplink messages (default: on) --no-sq Don't display messages with SQ label (default: on) --no-empty Don't display empty messages (default: on) --no-console Disable logging on console (default: on)
Third question: I have VRS running on the same pi, thus I set : --vrs-url http://127.0.0.1:8081/ However no pictures are rendered. The database seems to work ok.
Fourth question: I suppose the CPU usage depends on the amount of frequencies you are trying to monitor/decode. I currently have these: --freq 131525000 --freq 131550000 --freq 131625000 --freq 131725000 --freq 131750000 --freq 131825000 --freq 131850000 --freq 131875000 The maximum range for an SDR is about 2MHz bandwidth, so I am unable to monitor both the 131 and 136Mhz channels? In that case, I would prefer to have 2 sdr's connected and running. Is this possible to have 2 instances of the software running? How many channels can be monitored simultaneously? Second range I would like to monitor: --freq 136725000 --freq 136750000 --freq 136775000 --freq 136825000 --freq 136875000 --freq 136900000 --freq 136925000 --freq 136975000
Fifth question: Yesterday I tried decoding on a generic SDR stick (blue cheap chinese dongle). While the acars were correctly decoded by streaming the spectrum to my pc and decoding it there, acarsdeco2 did not decode a single message for over an hour. The generic dongle has a lower signal to noise ratio, but it should not result in no decoded messages? I usually use the SDR Blog V3 dongle with the provided dipole.
Kind regards
