N1SU APRS Digipeater & TX IGateConfiguration and setup overview by Jason Buchanan
The crossband aprx.conf configuration file is availble for online reference. This configuration includes weather and radiation monitoring via geiger counter sent to UHF and VHF every 30 minutes - this configuration provides interesting data to view propagation changes. The weather data is never sent via APRS-IS and this is intentional, as it intended to be received by UHF and VHF gateways.
N1SU-2 (VHF, 144.390) and N1SU-4 (UHF, 440.800) provide full duplex APRS digipeater and internet gateway services, allowing you to send messages and receive replies using only your radio, no internet or cellular service required.
