I was in town yesterday and monitoring fire (154.325, PL 118.8) and noticed I was receving a transmission that wasn't getting past the CTCSS setting. I turned off the PL and started hearing traffic for a medical aid call. I wondered if I had the wrong CTCSS programmed in. I later heard a fire callout and during the transmission reenabled the PL. This time the transmission was getting though using 118.8. I'm now wondering if certain calls are broadcast without the tone. Anyone know?

Do you know if it was for sure a Santa Cruz Co medical call you were hearing? Maybe it was another agency on the same frequency?

Thanks for the replies!

silagi: I'm not completely sure it was a Santa Cruz Co med call. Looking at the RR database I don't see any other nearby users of the frequency so I assumed it was.

mmckenna: Are you saying 118.8 is the input tone to the repeater and 162.2 is the output tone? If so the RR database probably needs to be updated. Where did you see it listed as 162.2?

Try 162.2hz as the PL tone when listening in on 154.325MHz.

None of my documentation shows any PL listed for the Fire Red output frequency, at least none of our radios use one. Fire Red is set to carrier squelch on that frequency. The input tone to the fire red system is 162.2hz, so give that a try. I don't show 118.8 listed anywhere for fire red.

I'll see if I can give it a try tomorrow. All my stuff is set to carrier squelch on fire red, but I'll check and see if they are TX'ing with a PL tone. Short of that, I'll call down to the county radio shop and ask them.

Also, looking at the SO's listings, there appears to be errors,

TAC Orange uses CSQ
TAC Green uses CSQ

The listing for SO black is incorrect. 154.055 simplex is Fire Black, tactical south, not SO, however the SO radios do have the fire frequencies in them.

The listing for SO brown is also incorrect. I don't show anyone using 154.555 in the county. SO brown is actually 155.475 simplex, which is also NLEMARS.

155.265 is the SO explorers only, not SO SWAT. SO SWAT uses SO Black, which is 155.010 simplex, CSQ.

155.235 is SO search and rescue, however it is more commonly called "Jeep Posse" or just "Jeep" on the radios with smaller displays. The SO radios do have the standard 155.160 SAR frequency in them, labeled as NASAR (National Search and Rescue). Some radios have it labeled as "Med. Rescue".

155.310 in simplex is used by probations.
155.310 with a different input and PL is the jail repeater.

The 155.16 entry is just SAR, not swat as it's shown.

155.220 simplex is listed as the Life Guards on my list, and shown as City of Santa Cruz "gold".

The 155.010 listing is SO Black, as I mentioned above, not "extenders" as listed. I've never seen any mobile extenders used by SO, but I could be wrong. Portable coverage is pretty good in most parts of the county.

OK, I updated your list and added a few things I had handy. I should probably work with someone to go through and update the city PD's in the county.

Santa Cruz County Fire (All Agencies except CalFire)
154.3250 CSQ Red (Main dispatch)
150.7750 192.8 Silver TAC
151.0400 151.4 Orange TAC
154.0550 192.8 Black TAC
154.1900 103.5 Yellow TAC
154.4150 151.4 Blue TAC
154.4450 CSQ Green TAC
155.3850 118.8 HEAR Net (Communications between hospitals)
156.0750 CSQ CALCORD (Statewide)

Medical:
Ambulance to Hospital:
463.0500 173.8 Med 3 "Medical Net"
463.1750 173.8 Med 8 Dominican Hospital and Watsonville Hospital

154.1300 141.3 UCSC Fire TAC. UCSC Fire Department system. UCSC FIre is now dispatched by Netcom via Fire RED (154.325 CSQ) Since county fire frequencies don't cover inside the UCSC buildings very well, often calls on campus will have responding units switch to UCSC Fire Tac, which does cover UCSC. UCSC Dispatch monitors and can dispatch UCSC Fire if necessary. UCSC Fire also uses this frequency for their fire alarm system testing. UCSC fire apparatus are numbered as 27xx units. 2710 is type 1 engine, 2730 is type 3 engine, 2760 is utility truck, 2790 is pickup truck. 2700 is Fire Chief, 2701 is assistant chief.

I submitted that pl tone awhile back they were using that pl tone and went back carrier squelch and I told one of the admins I cant remember who and thought they changed it back till I saw this thread sorry about that. I have Monterey county's fire load out that has all Santa Cruz CO frequencies. Also does anyone know if they are going to build out a new system of just narrowband? I see they have two new frequencies I wonder what they are going to use them for.

Great info. I will update the database accordingly within the next day or so. If you'd like faster service please create a database submission for Santa Cruz county and one of the other state DB admins may take care of it first.

Not sure exactly what you are asking here.
Can you elaborate on that question?

Is Santa Cruz county going to build a new radio system? Or just going to narrowband their current frequencies? I remember awhile back they were talking about building a new radio system.

http://forums.radioreference.com/ca...nother-p-25-article-santa-cruz-newspaper.html


Edit: After reading the user meetings all fire frequencies went narrowband back in 2011. SCSO and county agencies went NBmid-October or early November.

No, no plans to build a new radio system. Fire was narrow banded back in the spring of 2012, same time CalFire went, and the Sheriff went in October, I think.

EBRICS and a few others were trying to suck as many agencies into their system as they could a few years back, but 700 MHz won't work well here. Every now and then someone brings it up and it gets shot back down.

Due to the topology of Santa Cruz county, VHF works pretty well. Even with that, channels like the Sheriff Blue and Fire Red have somewhere close to 22 sites (most RX only) to cover the county. Trying to do that on 700MHz would need a lot more sites, not to mention all the infrastructure to support it. There are a few hundred radios alone that would have needed replacing, not to mention hand packs, repeaters, and remote receivers. The prices quoted in the Sentinel were optimistic at best. Considering that I have a hard time covering the UCSC campus with the single site 800MHz system, and that's only around 2000 acres. Multiplying that across the county, then multiply the cost times 4 because it would be P25, and you get the idea. Even when the cell carriers want to put up a new site the tin foil hat crowd comes out of the woodwork to protest, the County trying to do that would turn into a big court battle.

I've talked with the guy who runs the county radio shop about the future of the radio systems for the county, and there just isn't any funding to do much more than keep the existing systems running. Narrow banding was strain enough on the budget. What he has been looking at is maybe switching some of the cities to basic 800MHz conventional systems and freeing up VHF frequencies for the rural areas. I even gave them some of my old MSF5000's from the old SmartNet system we had to try out.

Thanks mmckenna for all the good updates. I do know that Boardwalk security (152.3150) uses a CTCSS (D565N). I sometimes listen to them while aboard the Roaring Camp beach train on it's one hour Boardwalk layover.

BTW, is NASAR exempt from narrowbanding (like marine frequencies) or has it been made to comply?
