Looks like Eureka Fire has gone digital this last week on 154.37. Nothing mentioned about it here or in the database. The internet audio feed is not feeding the fire dept now because of this recent change.

Any change in freq that you know of or just the switch to P25? I'll be over there later this week and can sniff around to find NAC's and whatnot. The north coast use to be the last spot in CA where you can run VHF high with no tone protection it was so clean up there. And now P25 is infiltrating...not sure many people over there even have digital scanners because there was no need unless you were interested in the prison.

Yea, no technical details for you, sorry, I don't own a digital scanner... yet. Last week the analog traffic disappeared on 154.37 and was replaced by digital hash sounding identical to the digital hash on Eureka PD's 154.95 primary frequency and yea the PD uses P25 I guess. I would guess that the fire dept is also P25. When the change happened last week, the fire dept simultaneously disappeared on the internet audio feed for Humboldt county. Earlier by about a month, I heard the same idententical digital hash appear on the older fire frequency of 153.95. Yea it's creeping in. Whoever is providing the scanner audio feed obviously has digital receive capabiliy since the PD is being streamed. I am on the hunt for a digital setup. Don't know who else owns one up here but for disaster work involving communications infrastructure failure, as a ham operator for decades I need to keep up with things. I need to be as "infrastructure independent" as is possible to be of service to the public in those more difficult times that I hope never arrive.

Interesting - yeah I just saw the PD switched to P25 it looks like last Fall? They were analog in August last I was over there. I'll poke around when I'm over there this week. With the number of VFD's and Arcata and CalFire all on the outskirts, I wonder what mutual aid looks like on a larger incident in the city, if the fire tacs are analog still or what.

So far, finding Eureka FD 154.370 is P25 NAC $293. N6HGG the digital hash is just that, the digital P25 traffic, the traffic is conventional, not trunked so there is no control channel (which would be a continuous data transmission with voice traffic on other frequencies.) Both Eureka PD and FD are in the clear. Unknown if the fire tacs are P25 as well, however the database and I've confirmed Eureka PD3 tac is P25. I'll submit for the fire dispatch change. Anybody in the future finding this post, program the Eureka fire tacs in mixed mode, or a digital one and analog one until we confirm.

Thanks, nice work. I'm schooling up my digital scanning so it's all pretty interesting. I've been a passive scanner nut for 50 years, since the crystal days.

I hear you on scanning since the crystal days. Hearing the neighbor's crystal scanner is what got me into this mess back in early 90's. I've always been a few years behind the trends just because NorCal has always been analogous to VHF-Analog, much like your sliver of coast. The metropolis of Redding had 800Mhz and that was fancy back then. Now with National Parks, BRICS and CRIS and some Fed 3 letters agencies I get to spool up on P25, TDMA/FDMA, simulcast, etc. which is old news to many other members here haha.

On any channel in your scanner that you're hearing that digital hash noise, that's P25 traffic being passed. It's a distinctive sound you'll learn to recognize. I submitted just the Eureka Fire Dispatch channel since that's all I could confirm during the time I was there. If you notice the fire tac channels or any other channels with that noise on it, can you submit those changes to the database, and/or post them here so someone can? If you have a P25 scanner, try programming each of those fire tacs twice, the first one being digital-only with NAC search, and the second being analog-only.

Does Eureka Fire play with the county well? There was a garage explosion and heavy residential fire in Arcata when I was there, and their 2nd and 3rd alarm kept pulling in more distant departments in the county but no Eureka Fire (that I recall) or CalFire resources. Thinking of interoperability where county departments have or don't have P25 capable radios to roll into Eureka if mutual aid was needed, if those fire tacs were indeed digital like dispatch. Even with dispatch/incident command being P25 and incoming mutual aid resources not getting the situational awareness as they respond in. Heaven forbid a 6+ hits over there and y'all can't talk amongst yourselves waiting for the 3hr response from Redding and north bay.
