Amateur equipment has no Certification (formerly type acceptance) except for commercial amplifiers/linears potentially capable of 11 meter frequency operation.
Previously managed a certification lab.

 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.
