Does anyone know if 36.50 MHz, VLAW31, and/or Marine 83A are still used by LARTCS? I just saw a document showing 39.46 LLAW1 as the low band frequency.

39.46 LLAW1

159.180 LARTCS-3V
159.030 LARTCS-4V

I'd be interested to see if anyone has heard the system active recently, and/or heard any frequencies not listed here.

Yes the 480 LASD stuff is active daily and available for cities
Tend to hear surveillance on the 800Mhz on a pretty regular basis along with occasional LAFD use.
The Federal interop also regularly heard - sometimes with surveillance other times patches to local agencies around the basin
Have heard radio checks on VHF

As I recall they have monthly radio checks on 3V-5V controlled by LASD SCC.

Does anyone know if LASD (480) is converting to LARTCS or to another network? I ask cos as of about 3 days ago, I am no longer receiving South LA Dispatch 12 (483.43750), LASD Lomita Dispatch 7 (484.03750), LASD Santa Clarita Dispatch 5 (482.86250) or L-TAC 2. The rest of the Dispatch freqs come in clear (contywide) as well as a majority of the L-Tac's. I ran an analysis for 24 hours and not a single transmission from those freqs in that timeframe.

As posted prior in the forums, LASD for the last year has been in the process of narrowbanding.
During this period frequencies will be down for a few days. Affected stations will utilize another frequency during the period.
