700MHz P25 in Sacramento? CHP??

[scannerboy02]

I was driving near the court house downtown around Noon today and got some P25 traffic on a 774MHz frequency I got off the "CHP 700MHz Channel Request" plan that was posted here on RR a while back.

I am not 100% sure it was CHP but the traffic and codes being used sounded a lot like CHP. I was able to hear a dispatcher and a field unit and the dispatcher was giving the field unit a address in Elk Grove for an "11-10 on a 10-8-51". I was not able to hear the field units ID but was able to hear the address and the field unit confirm that he got the address.

Most likely one of the new CHP Extenders.

i've been searching for this 700mhz channel plan, could you link to it?

Keep an ear on 773.53125 in NorCal. I don't know if it's installed yet but it will be if not.

 

[avtarsingh]

anybody have a good 700 plan they can submit so it can be added to chp page ?

 

[mkewman]

scannerboy? could you link to this 700mhz plan?

Today I picked up a very weak P25 signal near downtown possibly from a CHP VRS on the BLACK (based on receiving a 47 unit).

Freq / Ch numbers per CAPRAD region 6 700mhz plan... CAPRAD C1
CH# Frequency NAC
71-72 769.443750



In theory this is one of the lower 16 (12.5khz) pairs for VRS
The offices then would more than likely be on the upper 8 (12.5khz) pairs

Where are you guys getting this "list" of 700 freqs? I'd like to add all of them to see what I can get.

Thanks

I think its self explanatory from here

I printed the list (more like a grid) from a link that was in a post here on the RR fourm, it was either in the California or Sacramento section. I have been searching for it and can not find it any more.

The grid has all of the 700MHz channels on it and is color coded for what channels are state license and what of those are for CHP. The grid only has the 700MHz channel numbers on it, I did the math to get the frequencies.

I don't have a scanner (the paper scanning kind) or I would scan it in and post it. I attempted to take a pic of it but the channel numbers are too small to make out.

If anyone has any other ideas for how I can get the page into my computer I would be happy to give it a try.

These are the channel numbers and frequencies (if my math is correct)

CHP will be in 12.5khz P25

The grid I have shows the channels in 6.25 but in a foot note it says the vehicle repeater will be 12.5 with channels 27-934 for the repeater transmit and channels 987-1894 for the portable transmit.

It use to be in the wiki, but I don't know what happen to it?
Northern California 700 MHz Frequency Assignments - The RadioReference Wiki

here is the excel sheet of it from NAPCO - Home

http://www.rgn6rpc.org/library/Region_6-Northern_CA-700_MHz_Chan_Allotments_5-14-09.xls

Chp 700 mhz

The attached PDF should help identify the CHP allocation.... ,.. Today 67-68 was active with P25 traffic but transmissions were short and I couldn't get the Nac captured...

This is the sheet I have, thank you for posting it.

I posted all of the CHP channels above but the frequencies are in 6.25kHz.

700 mhz p25

Well sofar it looks like it is a very small number of vrs units are out there or perhaps only being tested... near the CHP hq and academy

It always seems to be a VRS for the black-2 in P25 on 12.5khz channels
67-68 short P25 didnt catch the NAC
71-72 nac D83
115-116 nac DB8
849-850 nac 7D4

on 6.25khz channel spacing the p25 signal is on both channels with the same nac.

 

[scannerboy02]

I am over at the Starbucks next to the CHP Academy in West Sac right now and getting great P25 on 769.4400. Sounds like it's the black, hearing 112 and 58 units as well as the dispatcher. I only have 396T's on me right now so I am not able to get a NAC.

I love not hearing the chop chop of the old extender, audio quality is very good.

 

[scannerboy02]

Also got P25 traffic on 769.7187.

"71-72",769.44375 nac db3

FYI I corrected the NAC

I think it might be appropriate to start submitting these to the DB. Please include NAC and possible office area. I'll try to get the ones mentioned previously in the thread in today.
