Maryland State Police freq list

  The standard PL MSP uses is 110.9 u.o.s in brackets.  The PL
info is from Scanner Master.

  MSP underwent a major revision of their frequency/channel pairings
a few years back, when the Baltimore County lo-band system was
pretty much abandoned when their 800 mhz system was installed.  So
anyone that was monitoring the county for awhile will recognize some
of these frequencies:

39.10   several locations  A1 Statewide F1  [none]
39.26   KGB 744   A2
39.24   same      B4  [146.2]
39.62   KGB 744   B16 Pikesville
39.34   KGB 744   B15 Pikesville [127.3]

Washington Metro Troop:

39.30   KGH 654   A10 Barrack L/Forestville
39.32   KGE 796   A9 Barrack N/Rockville
39.26   KSU 469   Barrack Q/College Park

Baltimore Metro Troop:

39.14   KGF 986   B9 Barrack J/Annapolis
39.04   KBT 576   B10 Barrack P/Glen Burnie
39.44   KGN 485   B14 Barrack R/Golden Ring

39.56   used to tie Md.State Police to Baltimore 
        County Sheriffs- especially useful during
        heavy snowstorms, riots, jail breaks, etc.

Northeast Troop:

39.32   KGA 919   B12 Barrack D/Bel Air
39.84   KGG 903   B11 Barrack F/North East
39.24   KIL 718   B13 Barrack M/JFK Highway/Perryville [127.3]

Central Troop:

39.42   KGA 915   A8 Barrack A/Waterloo
39.40   KGA 918   A6 Barrack B/Frederick
39.52   KGA 917   A7 Barrack G/Westminster

As Gary McGinnis and Bob Hale reminds us, MSP patrols in Carroll
county, so the Westminister barracks are echoed on their 800
Mhz system.  So from time to time, you will see MSP vehicles
with the tell-tale 'cell phone' looking antennas.  Of course,
they do also use cell phones from time to time.  I'm not sure
whether all transmissions on 39.52 are echoed, however.
Lindsay Blanton's web site has a good listing of talkgroups
for the Carroll county system.

Southern Troop:

39.06   KGA 916   A11 Barrack H/Waldorf
39.38   KGD 716   A12 Barrack T/Leonardtown
39.28   KGD 979   A13 Barrack U/Prince Frederick

Eastern Troop:

39.78   KGA 913   B6 Barrack E/Salisbury
39.96   KGA 912   B7 Barrack I/Easton

Detachment/Cambridge

Detachment/Denton

39.80   KGD 631   B8 Barrack S/Centerville

Detachment/Chestertown

39.60   KZT 386   B5 Barrack V/Berlin

Detachment/Princess Anne

Western Troop:

39.24   KGA 910   A4 Barrack C/Cumberland
39.34   KGA 914   A5 Barrack O/Hagerstown
39.08   KGA 910   A3 Barrack W/McHenry

Other Frequencies:

39.66   Criminal Investigation Division (CID) [?]
44.74   MSP Medevacs (SYSCOM) **
        You can also hear locator data bursts here that evidently
        can be read with a good packet TNC
47.66   MSP Medevacs (patient status to hospitals)

The freqs listed to MSP Marine (39.20 and 39.22) were transferred
to the DNR some years back.  This was reported on my Listening Post net by
Terry Turchin WA3DZZ.  Thanx also go to Shawn Crossland who
verified some of these.
