Feed Notes

In Hunterdon County, for county wide EMS communications, 155.205 Mz., or "AMBO 2" as it is referred to, is used as a broadcast only (one way) EMS alert/dispatch from the Hunterdon County Communications Center (911) ("HCCC") using Motorola Quick Call II alerting tones. It is also used for Fire alert/dispatch in the same way. For EMS on scene operations, inter-EMS agency and HCCC contact, 155.400 Mz (two way, repeater), or "AMBO 5", is used, and generally without other non-EMS emergency services traffic. In some cases, to relieve EMS traffic congestion on AMBO 5, dispatch will direct an incident to use "Tac 1", or 154.965 Mz. Occasionally, Fire will use Tac 1 as well, particularly for medavac landing zone operations. Fire communications are done on primarily on UHF frequencies, not VHF frequencies. NJ State Police will also use Tac 1 to contact county communications.

Most Hunterdon County EMS, Fire and Law Enforcement agencies have individual private communications channels. Occassionally, statewide EMS channels are used (JEMS) and NJ State Police channels are used (SPEN), of all these channels, SPEN 4 is the most common channel used. None of these channels referenced in this paragraph are broadcasted through this feed.

The radio scanner used for this feed is a Uniden Bearcat BCT15X. It is connected via low loss LM400 cable to a Diamond discone antenna that is about 35 feet above ground. The antenna is in direct line of sight of the Hunterdon County Communications Center (911) about one mile air distance away. The scanner and the personal computer used to stream via cable Internet are on uninterruptable power supplies that are further backed up by a manually started emergency power generator. The Internet connection is also backed up by manual fallback to a cellular telephone with Internet access. A second radio scanner, a Radio Shack Pro-2004, can be employed to replace the Bearcat scanner if required.

Audio delay: due to the nature of streaming audio over the Internet and the processing required, there is a variable delay up to 25 seconds from the time of the actual radio transmission until it is heard on a personal computer monitoring the feed.
