APRS national freq is 144.39 simplex as far as I know. There are a number of IGATE links I think they are called, that are interfaces to the internet. I use a simple 'tiny-trak' , GPS, and one 5 watt radio. Setup is rather simple to do and I leave it on all the time. We probably have about 8-10 users in our club who are connected at all times.
If there is another freq used on 2m , I don't know or have never used it.
