[TrunkCom] New GRE scanners

[Steve Matzura]

Scannermaster, my  most fave place to order this stuff from, has let
me down.  They don't even indicate that the 500 and 600 are different
units.  The description for both is exactly the same.

I also see by the frequency coverage list that there are big gaps in
the GRE coverage, like between 54 and 108 is totally blank.  What
happened to amateur 6 meters and between 174 and 216mhz?  Just because
analog TV is going away doesn't mean I don't want my radio to have
that coverage.
