Hello RadioReference!
I'm using an RTL dongle to listen to LASD frequencies in my area, and I'm confused about a few things.
1. I understand the busy tone, but why is it sometimes a steady pulse of beeps and other times it sounds like morse code?
2. With SDR# I get a waterfall view of about 2MHz of spectrum, and I often see the same audio being transmitted on 2 or 3 different frequencies, or I'll hear dispatch audio for areas nowhere near me on my dispatch channel (aka. hearing audio for Venice on Temple dispatch).
3. I keep hearing "415 family on _____". What does that mean?
4. Lastly, how come I'm picking up some LASD audio on frequencies not listed on RadioReference?
Thank you!
