So exactly what Public Safety transmitters/repeaters are on Mt. Wilson?

[karldotcom]

I heard the news say LAFD and LAPD, and I am pretty sure that isnt correct. I heard another account stating FBI, USSS, and other Federal agencies. Anyone know? (I can never figure out the geosearch option on the FCC page)

I can confirm that there's a ton of Federal stuff up there; it's high profile for them.

LA County has a large site just below it at Mt Disappointment which could be some of those hits you show.

I searched 1 mile....and those LA County freqs arent SO or FD....some looked to be flood control.

The sole City of LA license on your list,

Call Sign/Lease ID Name FRN Radio Service Status Expiration Date

9 WNSZ607 LOS ANGELES, CITY OF 0016433013 PW Active 10/03/2015

is for one of the several dozen 173.075 LoJack base transmitters across the state, all of which are licensed to the City of LA. And that's actually on Mt Harvard, a little over a mile SSE of Mt Wilson.

I heard the news say LAFD and LAPD, and I am pretty sure that isn't correct.

I agree, Karl. And while the contact person listed on the WNSZ607 appears to be someone at Commercial Crimes Division (Room 302 at Parker Center) which includes the Auto Theft section, they are not LAPD or even City of L.A. owned/operated transmitters. The City's Information Technology Agency only assists LoJack Corp with the licensing in California. LoJack owns the transmitters and handles the planning, engineering, construction, and maintenance of its system. In each state one law enforcement agency handles the LoJack licensing statewide; normally it's the State Police.

LA County has some CWIRS county trunking on Mt. Wilson. Road yard and flood control if I remember right. Mt D would be much worse a hit for LA County.

I've looked at the repeater locations for a lot of public safety agencies in southern California. I've not run across much at all on Mt. Wilson, which has a high RF environment due to the number of TV and FM broadcasting stations located there. Mt. Lukens and Johnstone Peak seem to be much more important for public safety radio. I haven't heard how badly the electronics have been damaged on Lukens.

Mt. Lukens and Johnstone Peak seem to be much more important for public safety radio. I haven't heard how badly the electronics have been damaged on Lukens.

It's hard to put the days and nights of listening in order, but I believe it was Monday evening or Tuesday that I heard a radio tech notifying someone else that one of the linked "command' repeaters was back in operation. Spoken in a firefighter/radio-man's typical droll manner, he said to the effect that "All we had to do was replace the destroyed antenna line and power cables. Oh, but we had to extinguish the fire in the repeater building first. Now we're headed for [somewhere] to check out that site."

Something in the northeast corner of my memory tells me it was Lukens that they were talking about, but don't quote me on that.

LA County FD hasn't lost any mtn top equipment that I know of. I'll check when back working Saturday, enjoying some time off finally.
