I got the chance to drive through LA last week on I-5 and listen to LAPD and LASD for the first time. The LASD busy tones were about as annoying as I was expecting them to be, LASD Aero and SUD (now County L-Tac?) had some interesting traffic, I loved LAPD's use of "Roger" in lieu of 10-4 (very Aeronautical/Military), and was disappointed with the P25 IMBE sound quality on all the LAPD dispatch channels I heard (are they using a REALLY early vocoder?)...
...but Air/K9 Hotshot absolutely stole the show. I had a preconceived notion that it would be moderately active (every 10-20 minutes?), and was totally blown away by the almost continuous stream of activity on it, with alert tones for new calls coming in seconds after the last dispatcher finished in many cases. It's quite an eye opening insight into just how busy LAPD is.
I would definitely listen to a feed.
