# A basic APRS iGate and APRS weather station with additional (optional) PE1RXF telemetry support
|
|
#
|
|
# This program reads the registers of the PE1RXF weather station via ModBus RTU and sends it as
|
|
# an APRS WX report over APRS. Additionally, it sends beacons and forwards received APRS messages
|
|
# to the APRS-IS network. All configurable via a YAML file called pe1rxf_aprs.yml.
|
|
#
|
|
# This program also has a PE1RXF APRS telemetry to MQTT bridge, which is configurable via pe1rxf_telemetry.yml
