San Diego City 700MHz System

[celbaseman]

To convert the 800 MHz system TG number divide by 16. IE: PD Northern, 208 on the 800 is 13 on the 700 system.

AHHHHH, I was looking at the HEX not DEC and seeing they appeared to be reusing the same talkgroup numbers.

The talkgroups on the 700 system are the same (in HEX) as the TGs on the 800 MHz system.

I find the 700 system to be extremely inconsistent on the BCD436HP. One transmission will sound terrific then the next one from the same dispatcher will be garbled and inaudible. I'd guess that professional radios don't experience the same problem as the scanner though.

Does anyone have experience with the Unication G4/G5 pagers or the SDS-100 on the system for comparison?

I have it on good authority that the City might transition to this system in July 2019. The company I work for does work for the Community College District, and we had to scramble to get 700mhz cards for their campus repeaters.

 

[SDBud]

If they had ANY plans to switch, I doubt they'd have wasted the time rebanding the 800 system

 

[Anderegg]

Bud, perhaps they will deprecate the old system to city workers and such. As it stands now, Mon-Fri 9AM-5PM, the 700MHz system is at 90% capacity, and that is just from the three most long winded garbage truck drivers!

New talkgroup 1395 Public Works or could be sanitation.

Could someone advise how to program the SD City 700 system into a 996XT scanner? I used to be able to receive it, but now, even on the correct 771.41825 control channel, and bandplan autofill or manually filled, it just says finding control channel, even if I manual hold on that frequency full signal. I tried Freescan, as well as manually creating the system from the keypad. I am at a loss. My Whistlers work fine on it.

[Anderegg]

I am using Freescan to try and manually enter the bandplan for the 700 system, and Freescan keeps telling me that 762.00625 is "out of band"..."you have been warned!" TFW???

 

[JoeyC]

You shouldn't have to set up a band plan. FWIW, you have the wrong control channel listed above. Its 771.48125

 

[Anderegg]

Sorry, got dyslexic. I am manually entering the bandplan because the 996 was unable to decode the control channel and auto-fill...I thought maybe prefilling the bandplan would help it see the system again. FWI, the control channel in the scanner was and is 771.48125.

 

[JoeyC]

I'm gonna have to check in the morning when the trash trucks hit the street if my 996 works on the system. It has in the past, but I don't regularly listen to that nonsense.

 

[JoeyC]

Yeah my 996xt is not working on this system anymore it seems. I don't remember how this radio display shows information. Every few seconds, not consistently though it will show the control freq on the 3rd display line, most of the time it says NFM. The signal bars occasionally show 5 bars while the freq is displayed, but it will not hold on the control it seems. The 536 is fine.

 

[Anderegg]

I think we are dealing with serious LSM issues on our XT's. I was able to get solid CC decode on I-5 and the 56, as well as 94 and 25th street, but near my station on 94 and 47th, I cannot get the system to CC lock, even though full signal, regardless of ATT state. The area on 47th where the CC will not lock is visual line of site to Miguel, Otay, Pt Loma and Soledad, so the little XT is seeing every tower at once probably at the same signal level. Oddly enough, the NextGen locks CC no problem same location...then again, not sure how many towers are broadcasting in LSM at this point.

[JoeyC]

Driving around with it today I got a solid decode on the control channel while driving in the Allied Gardens and Mission Gorge area but only briefly. The scanner struggles to keep hold of the CC and most of the time cannot. Stationary at home, it would only briefly catch the CC and the scanner spent most of its time in search of a usable signal. I wonder if some transmitters have recently been activated because as I think you said before, I don't remember it being this bad in the past, then again, I don't listen often.

Hearing Mid-City currently patched on the 700 system.

[Anderegg]

Mid City has been 24/7 patched to the 700 system for the last week...now Northern is patched as well.

Confirmed Talkgroup 253 as SDPD training 3 which on the 800 system is 4048.
