[Scan-DC] Police Interoperability

[JoeBradley]

One of the bottom lines here for msp is that the majority of their ops are either on low band or vhf w/ the exception of some of the rockville units (n barrack) which operate on part of montgomery counties 800 astro trunked system. Initially when Mont Co switched over there seemed to be some fcc laws in place that prohibited the helo's from transmitting on the 800 channels due to air travel. Then there was the case that their wulfsburg or even newer mutli band radios were not capable of transmitting on a digital or even 800 mhz band channel and the company that makes their radio didn't offer and didn't plan to offer any time in the near future a module that would be capable of that bandwidth.

Too bad they couldn't work out some kind of patch ahead of time.

My 2 cents.

  Shameful, utterly shameful. First someone has completly out of date information (453.2 was indeed Baltimore citywide pre trunking), they couldn't patch over to 460.05 (Metro) and most surprising of all, didn't know about the use of the ITAC/ICall frequencies which are supposed to provide this kind of interoperability. And I can't believe that no one in either are knows about the digital trunkers...

  Someone over in the comms area at MSP and Baltimore city needs to become better informed.  Utterly pitiful.

All,

In the 1500 hour EST on 123.025 Maryland State Police helo Trooper 1 was 
chatting with Baltimore City Police helo Foxtrot 4, asking for help on a city-wide 
freq they were supposed to be operating on.

Trooper 1 indicated there was a high-risk joint police op involving the State 
police and Baltimore City police and they were supposed to be listening on 
the city-wide freeq in case they were needed for medevac in case an officer was 
injured during the operation. Trooper 1 indicated that all they had in their 
radio for a city wide freq  was 453.2 but that they was no one on that freq. 

I could weakly hear the Baltimore PD controller pass a freq to trooper 1 who 
indicated that it must be a trunked freq and that he couldn't operate on their 
trunked system. Trooper 1 then indicated he had receive subsequent info that 
they were to operate on the Metro freq (nfi). Foxtrot 4 acknowledged and said 
that should work.

Trooper 1 was exaspirated with the interoperability problems bemoaning the 
fact that they had millions of dollars tied up in their platform and they 
couldn't talk to folks when they needed to. Trooper 1 ended by saying that next time 
they would bring some tin cans and some string which would work better.

Foxtrot 4 indicated that they had tried to switch all the players to channel 
16A (nfi), probably on the trunked system, but that didn't work either and 
they were all trying to link up in the Metro System.

In the late 1500 hour, Foxtrot 4 offered to relay comms from channel 16A to 
Trooper 1but informed Trooper 1 that they couldn't get any comms from channel 
16A themselves. Foxtrot 4 told Trooper 1 they couldn't raise anyone and had no 
info on the police operation. Troopr 1, finally exasperated, indicated that 
with no info on the operation and no comms with the folks involved that he was 
heading back to Martin State.
