California Radio Interoperable System (CRIS)

[ogppc]

A little activity on Mt. Oso this morning..

TGID 783 NAC 9D2h

"Radio test on the white."

 

[ogppc]

Hope it helps in the DB

Probably CHP VAL WHITE

 

[ogppc]

Thats kind of what I was thinking too

Looks like the Town of Mammoth Lakes is planning to join CRIS with additional sites at Lincoln Mountain and MLFPD Station #1

It looks like the Mammoth Lakes FS1 site is on the air with 151.1000 as the current control channel. Callsign is WRZR827.

151.1000 Control on air now
155.1675 Listed as Control
155.7225
156.105

I have not logged any actual traffic, yet. More details as I figure them out.

We’ll need the site number in order to add it to the database. The NAC and neighbors would be great too.

The NAC is 9D9. No traffic is transmitted, only PDU, TDU, and TSDU packets are sent. I have monitor but not seen any site ID or other network info transmitted.

I am thinking that the transmitter is hooked up and being burned in, but not connected to a controller or network, so in the very early stages if it install.

I am using DSDplus public. Any suggestions to sniff more out of thus site?

There must be a site number. Are you able to post a screenshot of what DSD+ is showing?

DSDPlus v1.101 and v1.074. -v4 logging. Only shows NAC, TDU, and TSDU packets and no site info.

Funny thing is 151.100 is in-between two Mono County Mutual Aid repepeaters: 151.085 and 151.115. Both are carrier squelch. A low power transmitter in the middle of nowhere (RF wise, I love Mammoth Lakes ;-) and they picked THIS frequency!

Hmm...I guess keep us updated when a site number pops up. Thanks

Yeah, it sure looks like they installed the TX and antennas and tuned them up and burning them in now. Likely now waiting for Telcom vendor vendor to deliver the needed circuits for the trunk controllers. I would not be surprised if the TX is currently configured as a conventional P25 repeater, with a data channel, or as a single site trunked system, but even that would have a site number.

I have heard nothing on the other frequencies on that license.

Anyone know if the TX or the controller generates the TSU and TDSU packets?

Can anyone recommend a better control channel logger that is Win10 freeware?

Sorry, but I am just passing thru, so no more updates. I just wanted to update folks to keep an eye on this site.

You can try Sdrtrunk. I would upgraded to DSD Fast lane

I have heard P25 conventional and trunked repeaters broadcasting continuous data that sounds like a control channel but doesn’t decode used for coverage testing before. I forget the official name for this function but once coverage testing is complete they replace the test channel with a control channel (if the system is trunked). That may be what you were hearing, but the free version of DSD+ is also quite out of date, so like others have said recommend upgrading to DSD+ fastlane to be sure.

On Motorola wide area P25 TRS, we have seen subzones turned on with just a carrier signal beacon that doesn't have any "useful" data for a period of time. Then suddenly each site has an actual control set up and we log site id, and sysid.... Then bam the subzone goes live with full data. (MSWIN, Entergy, SAFE-T, I have seen this on, with SAFE-T, and Entergy being upgrades from ASTRO Smartzones to ASTRO-25. MSWIN was a whole new set up from ground up.) Also noted this on the growing Duke Energy system. Sites beacon, then go live, then go TDMA CC.
