For those of you who are new to this, or those of you who maybe interested, I decided that I would have a crack at providing some info for the London area...
Freqs in use:
147.150 - 147.4875 plus a couple between 147.5375 - 147.675. These are the local stations cars & "bobbies on the beat"
152.000 - 152.550. These are the Scotland Yard (or Information Room) Also in this area are the "Oscar" Channels (Traffic)
152.550 - 158.000 These are the channels used by CID and other special services like prison escorts etc.
All of the above are 12.5Khz spacing using NFM.
The Met are very careful about how call signs are assigned. To give an example I will use Station MM (Peckham SE London) which is in M District, Which is in 1 area, below are the majority of the ones I am aware of...
MM1 - Station Officer (usually an Inspector)
MM2 - Sherpa Van
MM5 - CID Car or Unmarked car (sometimes uses MM7 robbery car)
MM21, 22, 23 etc. - IRV (Instant Response Vehicle - Astra)
MM81, 82, 83 etc. - Panda (Metro)
MM54 - Chief Inspector
M1, 2, 3 etc. - Area cars
M0 (zero) - Dog van M599
M - District TSG HQ
M99 - A Prison (does not exist in Peckham but R99 is HMP Belmarsh SE28)
Uniform 511, 531 etc. - TSG (Territorial Support Group - Long wheelbase Transit)
Trojan 501, 551 etc. - ARV (Armed Response Vehicle)
Trojan 99 - ARV HQ based in Old Street
India 99, 98 etc. - ASU (Helicopter) Operates out of Lippetts hill
CP1 - City of London Police
CP501 - City of London Police ARV
"Tracker" is a service which is operated by a private company which is endorsed by the Police. When a vehicle fitted with a Tracker device is stolen, the equipment is activated and sends out a radio signal tuned to an exact frequency (unknown) Most traffic cars & and the helicopters are equipped to receive these signals, and can trace the stolen vehicle by bearing and distance.
"Stinger" is a little device consisting of a string of spikes which can be laid across the road in front of a vehicle refusing to stop, it basically punctures all 4 tyres, and gee I guess you stop.
"Night sun" is the searchlight on the helicopters.
"T I" is the Thermal Imaging camera on the Helicopters.
"PNC" is the Police National Computer used to do checks on peoples names to find out if they are known or wanted for anything.
IC1 - White Person
IC2 - Latin
IC3 - Black Person
IC4 - Indian
IC5 - Oriental
IC6 - Arabian
All the above are used to describe a person's Race/Colour
"Fatacc" (pronounced fate-ack is jargon for a Fatal Road Traffic Accident (RTA)
"Polacc" (pronounced poll-ack) is jargon for Police Accident (Police vehicle damaged)
"Vicinity only Polacc" is a civilian vehicle damaged during a chase
"Time check at MM in X minutes" (or any other station callsign) is a cunning code for telling everybody that the kettle is on!!!
That's about all I can remember for the moment.
I would like to keep this Faq as up to date as possible if there is anything that I have missed or mistaken please Email my Anon address and I will endeavour to add/amend.
If you do not want use the Anon server just post a followup in this group [alt.radio.scanner.uk]
Happy Scanning - Have a good Christmas & New Year.

Re: London Metro Police Radio
Hello, when I was over there in about a year ago. They seemed to be on a
Motorola Type II UHF trunked system. The portables were MTS2000 with an odd
looking public safety mic. The freqs are in the 450.0125-452.9875 MHz range
and they seem to have at least 20-30. I was using an older TT scanner and
couldn't track the UHF system.
I may be off on the freqs, but am sure they are on an UHF Motorola trunked
system. I had no luck finding fire/rescue frequencies though (any
suggestions??). When I go back in 2002 I will figure it all out w/ my TT-2
and post something. I also understand it is illegal to intercept public
safety and government radio transmissions in the U.K.
