NEW and IMPROVED SCANNER RADIO AUDIO STREAMS!
Try these links or players and choose the one that works for you.
They all get the same stream.
If the SHOUTcast server is full, use the RadioReference player.
Streams are also available from these broadcasters:
If you have any difficulties in receiving a stream, please send us an email and we will attempt to help you. Technical information for this scanner radio and its broadcasting methods is at the bottom of this page.
This scanner monitors all first-responder frequencies listed below (Law Enforcement, Fire, Ambulance and Coast Guard). There are many more active frequencies on the North Coast, and if you are searching for North Coast California frequencies to program into your own scanner, an excellent resource is http://harrymarnell.net/. That site also supplies the scanner feed for Humboldt County north of Eureka.
Our scanner monitors several frequencies used by pilots at local airports. These airports are all uncontrolled, meaning they have no tower nor a traffic controller. Pilots announce their locations and landing intentions over the air to keep track of each other. Depending on the aircraft's altitude, you may hear aircraft transmissions from as far away as the Arcata Airport, nearly 30 miles to the north. If you are interested in sport aviation, please visit our web site NorthCoastAviation.com which showcases webcams installed at nearby airports.
If you hear short telemetry bursts you are likely listening to the International Space Station. These continuous digipeater mode signals are in the 2 meter amateur radio band (145.800 and 145.8250 MHz). The Space Station orbits the Earth about every 90 minutes but the signals are received only for the few minutes while the Station is within range.
Update, 2/2011 We added equipment to our network and DSL circuit allowing us to continue broadcasting scanner audio and weather updates during power interruptions. It was put to the ultimate test several weeks after its installation when the area suffered a power loss of nearly three hours. We are pleased to report there was no break in the service.
Update, 9/2011 The analog output from the scanner is now being fed to a Barix Instreamer, a dedicated IP Enabled Audio Encoder (client streaming appliance). More information
Update, 2012 We are replacing the existing Radio Shack PRO2041 scanner with the GRE PSR-600, allowing us to use the ARC500 program to change the thing's parameters from our workstation. Because the PSR-600 is so sensitive we will need to get it out of the network closet. We are running new antenna cables and continuing the testing.

This scanner has been available on the net since right after broadband arrived in this area in early 2004. Our local network generally had enough bandwidth then to satisfy up to 16 simultaneous connections. For a number of years this was sufficient, but had to change after the large local earthquake of January 2010 when many hundreds of listeners from all over the world were attempting to connect and were disappointed upon receiving "Server Full" responses.
In Fall 2010 the audio stream was moved to our SHOUTcast server located in Los Angeles, tripling our capacity. At the end of that year we also added the broadcaster RadioReference.com. By utilizing these two services we are able to supply unlimited connections. This was very ably proved the following spring when the Japanese tsunami arrived on the West Coast and the two audio servers supplied hundreds of connections during that incident. One of our web servers which hosted the local webcam image monitoring the Eel River was also tested during the tsunami's arrival, serving up that webcam image 310,000 times that day. It didn't even break a sweat.
This scanner radio is located near the Rohnerville Airport in Fortuna, on the rugged and beautiful North Coast of California, at approximately 200 feet elevation. This location provides line of sight to all of Fortuna and to most of the Eel River delta. It has excellent reception of all North Coast mountaintop repeaters. The antenna is a vertical VHF collinear about ten feet long, mounted at the top of a short mast.
The current scanner is an old warhorse Radio Shack PRO2041. Its analog audio is fed into a Barix Instreamer which processes and formats it into a digital stream. The digitized bits are then wrapped inside packets and streamed to the SHOUTcast server in Los Angeles and also to the Radio Reference Icecast service. Each listener gets an individual stream from these servers. The processing and buffering adds a delay, so after you hear the sirens, you may still be able to hear the original dispatch!
If you are a local Humboldt County listener, those packets come back up on the same fiber optic line that we use to send them down to the servers. To get to you they take a round trip of about 1,500 miles, which takes about a hundredth of a second at the speed of light.
In early 2011 we added equipment to our network and DSL circuit allowing us to continue broadcasting both the scanner audio and the weather updates during power interruptions. It was put to the ultimate test several weeks after its installation when the area suffered a power loss of nearly three hours. We are pleased to report there was no break in the service.
