Sounds good Ken, yes AIRINC is on 130.8/Enroute and 131.95/Pacificnet. You'll hear airlines checking in to SF radio for HF freqs, and an occasional medical, or maintenance issue with company. I think the xmitter is near LAX.
At night, the pattern is reversed at LAX, and the arrivals are over the water, and many of the sectors fold down to the controller doing 124.9.
Also the Special Flight Rules Corridor is on 128.55, has small aircraft at 3500'/4500' self announced traffic, somewhat routine stuff.
ZLA's Sector 30 is directly overhead on 119.95/277.4. The VHF side is very busy, as it's somewhat the hub of many airways, very routine stuff though. It's so busy, your scanner may never stop on anything else, so maybe suited for one side of left/right channel thing, or separate scanner, IMHO.
However, the UHF/277.4 side (if your capable) is very cool, as the ANG CAP flights, and anything military in the area tends to hang out on that freq.
The USCG LAX station is on 345.0 and you'll get the Coast Guard helo ops, and rescues on there, good freq.
Have fun in LA! Mark
