• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I live in the tidewater area of Virginia. I have three questions.

1, It seems I hear less state police radio traffic every month. Is more encrypted?
2. I see even the new police cars are equipped with a low band antenna. Is this for CB or is it for the old sirs mutual aid radio.
3. On that note I never hear traffic on the old low band sirs radio system. Some times I here a trooper self dispatch and tell the radio room he was notified of a incident from what ever county he is patrolling. Some times the radio room will dispatch to assist county units. Are they using cell phones in the vehicles and talking directly from the car to the local counties.

Thanks fore your help. I'm sure many of you have more experience on stars that I do.

Which antenna are you referring to as the lowband antenna? Around Hampton Roads I see 3 antennas, a small antenna for lowband, a large VHF whip, and low profile 700/800 antenna.

VSP SIRS and other comm activity

1. One of the main reasons is more VSP dispatch/mobile comms are via MDTs. Some VSP and other STARS user's LE related comms are encrypted by design. For example, DGIF's original STARS comm policy was truck mounted MDTs would be used for primary comms and voice comms were to be used for backup comms. The policy later was changed to encrypt all comms although occasionally a few can be heard in the clear.

2. The low band antenna is for SIRS. Years ago before STARS, a few VSP mobiles may have monitored CB Ch. 9 but that practice eventually was stopped. SIRS comms are active primarily in the more city/county rural areas. Years ago before trunked systems many city/county metro areas decided not to use SIRS and stopped monitoring because it was too "distracting" to their "regular" comms. Later some of these trs users added SIRS as a separate talkgroup but a few others, as far as I know, still don't use SIRS.

3. SIRS comms by design were to be between a VSP mobile to mobile and/or mobile to area city/county dispatch/mobiles but not direct mobile comms to a VSP dispatcher. Within the past three years several SIRS repeaters were licensed/installed in selected rural areas which additionally include VSP direct dispatch/mobile comms capability. Some VSP mobiles additionally have 4 vhf antennas configured in a diamond pattern for LOJACK stolen/vehicles reception/tracking signals on 173.0750 mhz. Other selected VSP mobiles have vehicle license tag reader capability.

Here in Hampton Roads VSP monitors ORION, and a lot of the local cities monitor ORION as well on Incident Command 1. This has taken the place of SIRS, at least in the Hampton Roads area.
