APRS Over Satellites
Successful listening with gqrx and the built-in AFSK1200 decoder
Installing Xastir to set up an APRS iGate
- http://xastir.org/index.php/Homebrew
- Use via command line after running XQuartz with xastir &
- Still need to do some configuration. Installation was done 2021-06-06
  - Xastir with RTLSDR
    - Need to use multimon-ng with rtl_fm and socat
      - rtl_fm -f 144390000 -s 22050 -o 4 -g 100 - | multimon-ng -a AFSK1200 -A -t raw - | sed -u -r 's/^.{6}//' | socat -u STDIN TCP-LISTEN:14580,reuseaddr,fork
        
        Then Xastir needs to have connect to an internet server with localhost:14580
        
        I set this to an alias start_aprs
    - Configuration
      - Run callpass to generate
      - Station
        
        GPS, comments
      - Defaults
        
        Enable RF->Inet OR 2-way
      - Interface
        
        Internet for APRS Tier 2 server interface (along with radio interface if want to function as igate)
        
        This should be allowed to transmit
        
        Password from callpass goes here
To use Xastir with SDR
- Run start_aprs alias
- Launch XQuartz
- From the terminal that pops up, run xastir &
How to pass messages to internet?
- Set up password by running callpass <callsign> to send and receive, add that to Tier 2 server interface config
- I added another internet interface and pointed it to one of the Tier 2 APRS servers. I haven’t seen anything on APRS.fi yet though.
  - Enable RF->Inet OR 2-way also needed. Verified on aprs.fi
Thinking about getting a Baofeng UV-5R for cheap APRS operation
- Got it
Get Started with APRS with RTLSDR and Xastir on Mac Hub Page
