# APRS
|
|
|
|
This is an on-going repository for the Automatic Positioning Reporting System (APRS) Network
|
|
This repo includes support for Direwolf, rtl_fm & kissutil
|
|
|
|
This repo is split into multiple directories with
|
|
|
|
"Cross-Band Digipeater Support"
|
|
|
|
"Simplex Digipeater Support"
|
|
|
|
"RTL-SDR RX Only IGate Support"
|
|
|
|
|
|
## Installation
|
|
|
|
You're going to need
|
|
|
|
"rtl-sdr" https://archlinux.org/packages/extra/x86_64/rtl-sdr/ (If you plan on using an rtl-sdr)
|
|
|
|
"direwolf" https://aur.archlinux.org/packages/direwolf (IIRC "kissutil is included in this package)
|
|
|
|
"telnet" https://archlinux.org/packages/core/x86_64/inetutils/
|
|
|
|
## Usage
|
|
|
|
Ensure that you clone this repo into your `/home/$USER/` directory so that everything can run seamlessly
|
|
|
|
_______________
|
|
|
|
To simply run direwolf for your rigs run
|
|
|
|
Simplex VHF: `direwolf -c /home/$USER/aprs/Simplex-Support/direwolf_VHF-APRS.conf`
|
|
|
|
Simplex UHF: `direwolf -c /home/$USER/aprs/Simplex-Support/direwolf_UHF-APRS.conf`
|
|
|
|
Simplex 10m: `direwolf -c /home/$USER/aprs/Simplex-Support/direwolf_10m-APRS.conf`
|
|
|
|
Cross-Band: `direwolf -c /home/$USER/aprs/Cross-Band_Support/direwolf_MultiBands.conf`
|
|
|
|
Everyone's setup is different, Please ensure you have checked your
|
|
|
|
`PTT` method (If you're using an RPi your PTT method will be via the GPIO pins)
|
|
|
|
You can find the documentation on GPIO PTT here: https://www.marcelpost.com/wiki/index.php/GPIO_pin_on_the_RPi_to_trigger_PTT
|
|
|
|
`ADEVICE` (You can find this by running `aplay -l` and `arecord -l`
|
|
|
|
_______________
|
|
|
|
If you intend on using "RTL-SDR(s)"
|
|
You're going to want to move `aprs-1200b.service` and `aprs-9600b.service`
|
|
from `/systemd-services/` to `/etc/system/systemd/`
|
|
|
|
To enable these as services so that they run on /BOOT/ run in your terminal
|
|
|
|
```
|
|
sudo systemctl enable --now aprs-1200b.service
|
|
sudo systemctl enable --now aprs-9600b.service
|
|
```
|
|
|
|
_______________
|
|
|
|
To run the RTL-SDR(s) by themselves and not as a `systemd` service simply just run
|
|
|
|
`bash 1200b_RTL-SDR_APRS.sh` or `1200b-10m_RTL-SDR_APRS.sh` or `bash 9600b_RTL-SDR_APRS.sh`
|
|
|
|
This should give you a `print` of whats going on in your terminal window such as packets recieved
|
|
|
|
_______________
|
|
|
|
|
|
This repo also includes a method to send messages to other stations by utilizing the kissutil
|
|
|
|
In the "APRS-Messaging" directory is a shell script that you will need to edit for your station
|
|
such as
|
|
|
|
```
|
|
USER="ab1cde"
|
|
PASS="12345"
|
|
```
|
|
Ensure you have this correctly changed for your station
|
|
|
|
Usage of running the script is very simple
|
|
|
|
```
|
|
bash aprs-message.sh "callsign you want to send a message to" "your message"
|
|
```
|
|
|
|
This will telnet into the APRS-IS system with your login details and first send the message over TCPIP
|
|
|
|
It will secondly send the message over RF over the KISS TNC via WIDE1-1,WIDE2-1,APRS,TCPIP
|
|

## Notes
|
|
|
|
The "direwolf_UHF direwolf_VHF direwolf_10m .conf" 's include an ibeacon to "TOOT"

Currently as far as I'm aware there is no easy way to get the RTL-SDR to run at 300 baud on Sideband for HF APRS
|
|
|
|
Short of using an SDR software such as "gqrx" and piping audio into a loopback device and creating a custom config
|
|
for decoding HF packets, This is unfortunely a limitation of the RTL-SDR software
|
|
|
|
## Future development
|
|
|
|
I will try to maintain this repo as best as I can,
|
|
I'm still working on some stuff in the background so expect changes from time to time
|
|
|
|
Until next push
