[FedCom] US Postal Service Frequencies?

[kennyblues at aol.com]

In the Boston area there are two new P-25 repeaters that have come 
on-line in the past month or so;
407.7750R/416.7750(Input)
409.9375R/418.9375(Input)
The 407. freq started first then the 409 freq came on-line and appears 
to be the primary. Notice the 9MHZ offset. The base is encrypted and 
mobiles are in the clear.

Hmm, sounds like another great project for a hobby related magazine 
columist(s) & this fine group of "frequency sleuths" to undertake, 
developing a nationwide listing of USPS frequencies in use.

Grove's "Federal Frequency Directory" 2nd edition, lists the potential 
of approximately 189 frequencies being used by the "Post Office" 
(search term): 86 VHF band, & 103 UHF band.
Further breakdown
"Postal Inspectors" 2 VHF highband frequencies
"Postal Inspections" 2 nationwide UHF frequency pairs
"Postal Security" 2 nationwide UHF repeater pairs

I would think that US Postal Service Radio Systems could be categorized 
in the the following general categories:

Facility specific -- Such as Mail Sorting/Processing Facilities, e.g. 
Operations, Management, & Security. These would most likely be 
geographic specific coordinated frequencies.

Geographic Area Specific --- Primarily bulk mail transportation 
operations of some sort. In my geographic area, local route postal 
delivery vehicles do not have radio comms installed. This may be 
primarily used in large metropolitian areas (e.g. NYC, Boston, SF, Los 
Angeles, Chicago, Denver, Miami, etc....

Nationwide Assignments -- Perhaps this would be the US Postal 
Inspection Service, where both repeater pairs & simplex freqs are 
predefined channels in the mobile & portable radios.

Chris Parris columnist 'The Fed Files', "Monitoring Times" magazine has 
had some frequencies listed, based upon his travels & monitoring in 
specific US geographic areas. Additionally, it appears that those 
"spectrum holes" (listed as such in Grove's frequency directory) has 
seen some USPS current usage (e.g. Springfield MA BMC)

Tom Kneitel's "The 'Top Secret' Registry of U.S. Government Radio 
Frequencies", 8th edition (1993), lists the following states with 
frequency information (format State: number of locations, number of 
frequencies):
AK: 1, 1 (VHF)
AL: 1, 1, (VHF)
AZ: 2, 4, (VHF & UHF)
CA: 11, 43, (VHf & UHF)
CO: 2, 5, (VHF)
CT: 2, 3, (VHF & UHF)
DC: 2, 3 (VHF)
FL: 5, 15 (VHF, UHF)
GA: 1, 10 (VHF, UHF)
IA: 2, 6 (VHF & UHF)
IL: 3, 17 (VHF & UHF)
IN: 1, 2 (VHF, UHF)
KS: 1, 1 (VHF)
KY: 3, 3 (VHF & UHF)
LA: 1, 3 (VHF & UHF)
MA: 2, 13 (VHF & UHF)
MD: 4, 10 (VHF & UHF)
ME: 1, 1 (VHF)
MI: 2, 5 (VHF & UHF)
MN: 3, 13 (VHF & UHF)
MO: 2, 7 (VHF & UHF)
NC: 2, 6 (VHF & UHF)
NE: 1, 4 (VHF)
NJ: 5, 13 (VHF & UHF)
NY: 9, 24 (VHF & UHF)
OH: 5, 24 (VHF & UHF)
OK: 3, 4 (VHF & UHF)
OR: 1, 2 (VHF)
PA: 7, 17 (VHF & UHF)
SC: 1, 1 (VHF)
TN: 4, 11 (VHF)
TX: 4, 23 (VHF & UHF)
UT: 1, 2 (VHF & UHF)
VA: 4, 7 (VHF & UHF)
WA: 2, 3 (VHF & UHF)
PR: 1, 1 (VHF)
All areas, 20 freqs (5 VHF, 15 UHF)
Postal Inspectors & Security nationwide: 5 VHF, 3 UHF repeater pairs, 3 
UHF simplex
So as you can see there's some states that are missing from his list 
but definitely have US Postal sorting facilities, etc....

So please post your findings to the list!
