Southern California - 153.83 - ???

[zerg901]

The short version -

Anyone know the PL for 153.83 in Tulare County?

Anyone know why Kern County had 3 portables on 153.83 in 1978?

Does Orange County have 153.83 in their VHF radios?

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

The long version follows

153.83 is sorta the USA FD primary fireground (FG) channel - FCC only allowed 10 watts on the channel up to ? 1990 ? - it was listed inside the front cover of Police Call for many years

searching for 153.83 in Calif in RRDB yields -

153.83 in Tulare County is Ch 3 - no PL indicated

153.83 in Hemet is Tac 2 with PL 103.5

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

Bonus point questions -

Any chance that Oxnard City, Burbank, Arcadia, Monterey Park, or Glendale presently use 153.83 as a Tac channel with a local PL?

Does Los Angeles County FD use 153.83 countywide or just in specific battalions?

IIRC 153.83 is available as a Statewide Tac with PL 0.0 - can anyone confirm that?

You can see that some of these licenses show 'first use' going back 40 and 50 years - so there is some history here.

Anyone know if LA County FD ever used 153.83 as a primary tac channel? Maybe in Station 51 days?

Over and Out

 

[f40ph]

"Back in the day" the state of CA had established a standing portable repeater pair with 153.830 input and 154.265 output (the old White 2). I recall many FDs had this pre-programmed in their radios but it didn't seem to get used much. This is probably why most licenses tended to be limited to low power.

 

[iscanvnc2]

Ventura County Fire as Fire Communications Center (FCC) dispatches for all fire departments in the county and assigns one of 3 command freqs for each incident. Each command has an associated tac freq. Tac 9 goes with Cmd 8 & uses PL 167 .9. Therefore Oxnard FD uses PL 167.9 on Tac 9. Once the Oxnard license, KC5485, expires I would expect they would operate under county license.
