800 MHz TRUNKTRACKER SPECIAL



The enormous popularity of the TrunkTracker has created new hope for scanner listeners that our hobby has not yet met its demise.  Nearly every jurisdiction in our coverage area has moved to a trunked system, or is planning one.

Unfortunately new systems will be mostly, if not entirely, digital.  But for the time being, we can effectively monitor several area jurisdiction's analog systems.  In this issue we've included details for analog trunked systems used by local jurisdictions and have made every attempt to make them as accurate as possible.

We have information on area 800 MHz digital trunked systems as well.  These include those systems already built or under construction for Baltimore City, Delaware, DC fire/emergency preparedness, Fairfax County, Manassas/Manassas Park, Metropolitan Washington Airports Authority and Montgomery County.  We have not included them due to space and the fact that the TrunkTracker is analog.  We also have limited information on the Baltimore Gas & Electric analog Motorola trunked system.

The 800 MHz trunked systems used by Prince George's County and Ocean City are EDACS -- an Ericsson/GE trunking format not trackable by the TrunkTracker.  We have talkgroup information if anyone desires it, however.  Dorchester County uses both leased and county-owned LTR trunked systems.  LTR is an EF Johnson trunking format that is not TrunkTrackable.


In this newsletter, frequencies used by each trunked system appear first, followed by a list of talkgroups.  In the talkgroup list, the first column, when known, is the talkgroup channel designation (what would normally be considered the channel number), followed by the Motorola and TrunkTracker talkgroup IDs.

Even when the TrunkTracker receives a strong signal, talkgroup IDs displayed by the TrunkTracker for a specific talkgroup may not always be consistent.  The problem is that the TrunkTracker includes the call-type digit when determining the talkgroup ID.  Motorola radios, however, do not rely on the call-type digit to determine the talkgroup ID.  Normally the call-type is zero (0).  When certain features are activated on a talkgroup, such as an emergency button, crosspatch, simulcast or encryption, the talkgroup may appear up to 15 digits higher.

In Anne Arundel County for example, 1-B would normally register on the TrunkTracker as 57392.  But because 1-B and 1-D are frequently crosspatched, the TrunkTracker ID for 1-B registers as 57395.  On Motorola radios, however, it remains the same talkgroup.

This multi-agency trunked system became fully functional for the entire county in 1989.  The four channels used by the controller seldom carry voice communication.  Can anyone identify what exactly 856.4125 is used for?  It does not appear to be part of the system.

Talkgroups are usually referred to by phonetic letter, sometimes prefixed with the bank number.  Most radios are programmed with only a small subset of talkgroups.  In some radios the talkgroup zone number and letter do not match the "master plan," such as talkgroups 3-N and 3-O.  Talkgroups 1-B and 1-D normally simulcast and their TrunkTracker IDs are 57395 and 57459, respectively.

This trunked system became fully operationally in February, 1991.  Fire battalions 6, 7 and 8 are intended as future battalions.  These talkgroups are presently used for special events.  Police Pct 4, Owings Mills, currently does not exist, although talkgroups have been reserved for its use.  Presently, Pct 3, Garrison, covers the Owings Mills area and officers from the Garrison precinct use the talkgroups reserved for Owings Mills for tactical communication.  The dispatch talkgroup for police Pct 9, White Marsh, frequently registers as 01874 and 01875 on TrunkTrackers.

The police department has several lesser-used talkgroups that we need help identifying.  We also need assistance identifying the talkaround frequencies used by the police and fire departments.  Those we know of are listed at the end of the police department section.  County local gov

ernment users have their own trunked system (listed after the public safety system).

Calvert County's system became operational for most county agencies this past summer, although many agencies appear not to have completed the move.  We've found about 30 talkgroups so far.  Some are not used much yet and we could use assistance identifying them as they become more active.

Many talkgroups in Frederick County's system simulcast and register on the TrunkTracker as two different groups even though they are actually the same talkgroup.  Although not indicated below, some talkgroups may only be used by Frederick City.  We have not identified talkgroups used by several key county agencies, such as housing, EMS, emergency preparedness, zoning, transportation and schools.

Alexandria is entirely a Type I system.  So the fleet map is worth taking time to enter into your TrunkTracker.  It is as follows, E1 USr: b0=S-12, b1=N/A, b2=S-12, b3=N/A, b4=S-12, b5=N/A, b6=S-12, b7=N/A

The trunked system became functional for the entire city in July of 1989.  The fire channels are presently 1-A through 1-M.  Under the new northern Virginia channel plan for 800 MHz fire radios, Alexandria's primary fire channels will be prefixed with a "2" instead of "1".  As an interesting note, 200-8 recently began carrying EMS consultations that were previously heard on 200-5.  Anyone know why?

867.0125 Smplx [156.7] 1-P Fire "Talkaround"

All county agencies except for the school system shifted to the trunked system during late 1993.  The trunked system does not offer telephone interconnect since command personnel carry cellular phones.  The talkgroup assigned to Di Lorenzo, the Pentagon's medical clinic, is used by the clinic mostly for administrative messages.  The snow emergency talkgroup, 200-05 (2-E), is often used for chitchat by county agencies.  The talkgroup used by local government users to contact the ECC in emergencies, 700-15 (1-L), is used after hours by the animal warden to talk with the ECC.

We're missing the conventional channel used in Metro tunnels that is identified as "System 9."  856.7625 does not appear to be part of the trunked system and may be that frequency.  Can anyone confirm?

Even though Arlington County is mostly Type II, the fleet map is still worth entering into your TrunkTracker.  It is as follows, E1 USr: b0=S-12, b1=N/A, b2=S-12, b3=N/A, b4=S-0, b5=S-0, b6=S-0, b7=S-4.

NewsScan will return in the next issue.  Meanwhile, a source at W*USA reports that we can expect to see several antenna changes in the coming weeks.
As of this writing, WRC is re-enforcing its tower for its HDTV antenna.  WUSA and WJLA, who share the same antenna, plan to erect a new dielectric panel antenna for VHF.  They also plan to mount a UHF antenna for the HDTV at the same site (Brandywine St and Wisconsin Av).  The transmit power will likely be reduced during installation times.  See if you notice any signal changes!

Also, try monitoring 85.1 MHz. It's being used as a digital test signal from the old WARW transmitter.
