Hi, I’m looking for a such software that allows to display ACARS togheter with Flightware map ( or any other feeder). At list, using the same dongle and dump1090-fa, in a separate map. Thanks ---

Hi so sorry for bringing up a old thread but was looking for info on the possibility of ACARS and thanks to you you came up in search results online 🙂 One question what are you using for a ACARS antenna if I may ask? Are you using a 1090 antenna or something like the ACARS/NOAA antenna from Diamond?; [ACARS/NOAA](https://www.hamradio.com/detail.cfm?pid=H0-016157) ---

Also bringing up an old thread as I am starting to look into ACARS. Have been listening with SDR++ on a Mac with a simple inside the house 1/2 wave dipole that I got with the RTL-SDR Blog v3 dongle. I can hear ACARS on 131.55, 131.725, 130.025, and 130.45 MHz. Also there might be others. If I install acarsdeco2 on the RPi, curious about how the software monitors more than one frequency. For example if the default values of 131.55, 131.725 MHz are used, how does acarsdeco2 monitor those two freqs? Is the SDR dongle tuned to halfway between those two freqs and then the software does the final tuning of each frequency to 0 HZ ? Also curious about how many different frequencies can be specified. It seems like there would be quite a load on the RPi, if 6 or 7 frequencies are specified. Also the spread of the frequencies can’t be more than about 2 MHz on an RTL-SDR dongle because that’s its bandwidth (assuming a sample rate of 2 to 2.4 Msps.). Also, how far does acarsdeco2 decode into readable English? The screen shots above seem to show not too far. Are there other ACARS decoders still available ? TIA for any info. ---

Ok, thanks for the links. I see the original author of acarsdeco2 (Sergsero), updated the first link in 2018 to show the latest configuration possibilities: 3 frequencies maximum with a spread min to max freq of 1.3 MHz maximum. I guess to add more frequencies you would add another dongle (and add another instantiation of acarsdeco2, since it can’t handle more than one dongle). ---

If you want to monitor more the three frequencies on a single dongle, you could take a look at acarsdec. It will do up to 8 frequencies within a 2Mhz span. > **[GitHub - TLeconte/acarsdec: ACARS SDR decoder](https://github.com/TLeconte/acarsdec)** > > ACARS SDR decoder.
