Monitoring police and fire MTD frequencies.

[romusd]

Just programmed listed LAPD, LASD, Fire, etc. frequencies in Los Angeles area into my scanner.
Is there ever any activity on MTD data freq.?
Or, should I delete them or lockout those data frequencies.
When scanning they never seem to have anything but unwanted noise. .

MDT's are Mobile Data Terminals. All you will ever hear on those channels is data. I wouldn't program them in.
