[FedCom] Interop Freqs Usage?

[Ken]

In the "Monitoring Times" magazine Feb 2006 edition, Larry Van Horn has an 
article "Interoperability: The Real Story" and he lists two pages of 
interoperability frequencies.

In the federal bands he lists about 33 VHF highband freqs & approx 53 UHF 
(399 to 420 mhz) interoperable, interagency, itinerant use freqs....

Take a look at the article but has anyone really ever head operations on any 
of these freqs, especially the new interagency authorizations that came out 
a few years back?

The NTIA's Red Book   http://www.ntia.doc.gov/osmhome/redbook/redbook.html 
also  has the freqs listed http://www.ntia.doc.gov/osmhome/redbook/4c.pdf 
but it may take it bit of work
to extract all of them....

Seems like a good research project in the future
