      How's this, Don... from the 1964 "Police Call:"

      LAFD
      33.70 B&M (F1) ((Los Angeles)) KMA706 "Westlake"
      ((Harbor)) KMA705
      "San Pedro"
      33.82 (F2) Command Channel
      33.90 (F3) ((Western and Valley Area)) K?Q236
      "Coldwater"
      33.94 (F4) ((Harbor)) KMA705 "San
      Pedro"

      Brian Humphrey... do you know if LAFD had a dispatch center in San Pedro?
      I'd only heard of Westlake & Coldwater. Has anyone done any kind of history
      on LAFD's communications? I believe it probably predated LAPD's if the
      street boxes are included. (Uh oh, I feel a project coming on....)

      I have some notes from around 1980. I think they are from something called the Los Angeles Media Manual. Ch1 506.3125 Ch2 506.5375 Ch3 506.9125 Ch4 506.6375

        I have some notes from around 1980. I think they are from something
        called the Los Angeles Media Manual.

        Ch1 506.3125
        Ch2 506.5375
        Ch3 506.9125
        Ch4 506.6375
        Ch5 506.6375
        Ch6 507.0125

        Channel 4 is for Metro area / zone Rescue Ambulances (507.1375)

        --------------------------

        I am not sure if this is from the Media Manual also.

        Channels 1 thru 6 are Div 1 FG + Div 2 FG + Div 3 FG + 2 brush channels
        + 1 ambulance channel

        Channels 11,12,13 are 33.60, 33.56, 33.52 for Chiefs

        ---------------------------

        July 1983 - monitored off the air probably - testing the 33.82
        transceiver on Oat Mtn - testing the 33.70 transceiver at Station 63 -
        (86 is a Paramedic Engine)

        -------------------------------

        14 June 1980 - LA Times - LAFD began (automatic) mutual aid into 4 areas
        - and began mutual aid with Santa Monica and Beverly Hills

        October 1980 Western Fire Journal - Beverly Hills FD now supplies a
        first due Engine company for fire and EMS calls in Coldwater Canyon (in
        Los Angeles City)

        --------------------------------

        from page 180 of my old blue hardcover diary notebook - LA City FD -
        33.48 (Ch12) - 33.86 - 33.60 - 33.70 - 33.56 - 33.94 - 33.52 - 33.90 -
        33.82

        Glendale - 6705 (?Mhz) - 6745 (?Mhz) - 460.525 Mhz

        LA - 959.60 Mhz - 956.?? Mhz - 6625 ?Mhz - (?links - 900mHz and
        microwave?)

        ?Los Angeles - the Baldwin Hills Base is linked to Verdugo by microwave

        Mount Lee is connected to Coldwater/108 by wire; and to City Hall by
        microwave; and to Westlake by wire

        154Mhz - PD Channel 9 LA

        47.44 - Civil Defense Channel - Los Angeles - Mt Lee transmitter

        (this might be 1965 data/info that I found in the NFPA Library in Boston
        around 1976 - they had microfiche, various reports, and a book called
        "Fire Radio Data" IIRC - it was FCC data provided in a book form by a
        private company IIRC - listed the number of mobiles and bases,
        callsigns, frequencies, control stations, etc)

        ----------------------

        from the 1979 Visiting Fireman (fire buff book) - Los Angeles City - Ch
        1 506.3125 - Ch 2 506.5375 - Ch 3 506.9125 - Ch 4 507.1375 - Ch 5
        506.6375 - Ch 6 507.0125 - Ch 7 Central and West and South 33.70 - Ch 9
        Valley 33.90 - Ch 11 Command 33.60

        Los Angeles County Fire - Central 154.43 Freq 1 - Valley 154.34 Freq 2 -
        Antelope and West 154.40 Freq 3 - 154.295 Tac 5 - 154.28 Tac 6 (Downey
        mutual aid) - [I wonder if 153.83 was Tac 4]

        --------------------

        Anything ring a bell with anyone?

        Yes, almost all of that sounds familiar and right on target. I m gonna have to print that out. In the early 80s, before 800-MHz arrived, LAFD used the 506/507

          Yes, almost all of that sounds familiar and right on target. I'm gonna have
          to print that out.

          In the early 80s, before 800-MHz arrived, LAFD used the 506/507 frequencies
          for fireground and Admin stuff, and for ambulance dispatch in the Metro
          area; they were still on 33 MHz for Metro & Valley Fire dispath (& valley
          RAs).

          For years Channel 9 (33.90) was dispatch freq for the SF Valley, but they
          eventually switched it to Channel 8 (33.82); I never heard a reason given,
          but I remember hearing Columbus (or was it Cleveland) Ohio FD just BOOMING
          in on 33.90 almost year round at different times, which may have been a big
          reason.

          Interesting stuff, Peter. Thanks
