Wow Andrew, 3,000 meters at 19,200 baud? That is that is a super-awesome 57,600,000 baud-meters! You should write a web page so we all can see the details of how super-awesome a ham you are!

Hi Cory. Welcome to the SIG. Sorry for Andrew's reply that had nothing to do with your question. He misuses the SIG to show everyone how he wants to or occasionally is able to do things that are 10-20 years behind state of the art, so I'm trying to give him the attention he craves. The other answers you got are much more on-topic.

I would add that the fact that we have an official North American APRS frequency is quite anomalous, no other specialized activity has been so honored. We got it through an odd combination of luck and hard work by accommodating the needs of the Amateur Radio on the International Space Station (ARISS) group during a tumultuous period some 18 years ago. We moved off a number of other frequencies (most importantly 145.79 in most of the US) and in return got 144.39 acknowledged by all the major Amateur organizations, and almost full time APRS digipeating on the ISS. Such an opportunity is not likely to happen again, nor is it really needed. Any use of 70cm for APRS will be local and can be coordinated with local groups. There are lots of frequencies available in most areas.

Hope you enjoy APRS, and feel free to ask any questions here you'd like, we love to help people get started.
