The 10-33 was probably for emergency traffic during the moment of silence. It's great they do that but they should have an "all units" channel (like EDACS has XX-000, or XX-YY0). RSO for instance had 02-000 for Amber Alerts.brandon wrote:Moment of silence and tribute audio clip: http://cl.ly/To9n/460.175.mp3

And did you notice all the bursts at the end of the audio? Those I think are since of the Riverside Police radio system aging.
Re: Rpd Officer Mike. C
If you would have listened to this clip, you would know the 10-33 was the start of the memorial broadcast. All of RPD knew they were going to do it, and if someone had emergent traffic, they would have the common sense to take it to another channel. All the keying of mikes at the end has nothing at all to do with aging radio system, it is the standard cop practice of acknowledging or agreeing with a transmission by keying up their mics...when everyone on shift does it, it sounds like this clip. Been there, done that.
Re: Rpd Officer Mike. C
I don't think Riverside PD needs an "all units channel" because the whole City is typically dispatched on CH1 except when they are "split City" and use CH 3 as a secondary dispatch channel. With RSO the stations typically each have their own channel which necessitates an "all units channel".
At the end of the linked recording, those "squawks" are the MDC 1200 data PTT ID bursts that identify who is keying up. As already mentioned, that was an episode of multiple officers keying their radios as some sort of show of solidarity in response to the message. (On many of the commercial radios this "squawk" can be muted so you won't hear it on the officer's radios.)
When RPD goes "10-33" on primary, all officers not assigned to the incident switch to CH2, so if there was a need to communicate during the message, officers could contact the dispatcher monitoring CH2.

Oh so THAT'S what those "burps" are? I've heard them on conventional systems and never figured out what that meant. I thought it was some squelch as the person released their PTT key.CQPSK wrote:I don't think Riverside PD needs an "all units channel" because the whole City is typically dispatched on CH1 except when they are "split City" and use CH 3 as a secondary dispatch channel.

That's what they are….1200 baud data packets. Those "squawks" are PTT ID's, emergency triggers, or can even be short messages sent by the radios. Lost or stolen radios can also be disabled and some repeaters can be set up & knocked down via MDC 1200 signaling. If you were to program up a radio on RPD CH1 that has MDC 1200 as one of it's features, you'd see the ID of the radio being sent at either the beginning or end of a transmission like you would see on the old EDACS system, etc. Your radio would also "light up" and display "EMERGENCY" if someone on the channel hit their emergency button.
