[aprssig] APRS on 70CM using a hundred "free" UHF radios

Not intended to throw any cold water on this, but are there any restrictions that might exist in using these radios on amateur frequencies?

FCC Equipment Authorization (formerly known as Type Acceptance) is specific about what radio services a product is certified for use on, although there have been some exceptions for amateur use.

Just something to double check.

Apparently the Motorola VRM650 UHF data radio should be available for almost free by the hundreds.

These are Motorola VRM650 modems which I think are a 40 Watt MCS2000 radio with a different faceplate and only a DB9 rs232 port.

We need to figure out an APRS application and figure out how to use them.

Apparently they are being forced out by FCC rules changes on the commercial bands.

But we need someone that knows how they network together with data… AS-IS to see if we can use as is for some kind of Amateur Network.

The first thing that comes to mind for me is to build the 2000 mile links along the Appalachians!

We test the path every year in the GOlden Packet Event: http://aprs.org/at-golden-packet.html

Here is the link on the above page to our dreams for an East Coast backbone.
