Heard Springdale Fire Dispatch 154.31 CSQ 12/05 JEFFCO 911 uses the callsign WPYY895 for Fire, EMS & Sheriff dispatch. 155.235 Fire Command B? 155.265 Fire Command C? Jefferson County Firefighters Website http://jeffcofire.org/

FREQUENCY NAME CHANGES EFFECTIVE JUNE 1, 2008 @ 08:00:

154.310 – Remains “JEFFCO DISPATCH” 

160.095 – Fire Main becomes “JEFFCO 1” - PL TONE IS 156.7 (Transmit Only) 155.355 – EMS Main becomes “JEFFCO 2” - PL TONE IS 123.0 (Transmit Only) 155.955 – Old Fire Main becomes “JEFFCO 3” - PL TONE IS 156.7 (Transmit Only)

All calls will be toned and verbalized on “JEFFCO DISPATCH”.

“JEFFCO 1” will be the primary response and radio traffic channel for all FIRE & EMS units, streamlining interagency communications. In times of increased call volume Jeffco 9-1-1 will utilize “JEFFCO 2” and “JEFFCO 3” for additional alarms. Responding units will be notified in the dispatch verbalization (2nd time) of what channel to utilize for that alarm. In the event that the responding units miss that information in the dispatch verbalization, upon their response they will be advised to switch to the appropriate channel.

Jefferson County 911/Sheriffs Dept's Radio uses a Simulcasting System, using the SYNCHROCAST technology. It was installed back in 2005 & 2006. All 5 sites are fully operational.

The FCC callsign for the SIMULCASTING system is WPYY895. There are 5 sites: - Arnold, Mo (Richardson Rd & I-55 -- SE Corner) - Crystal City, Mo (0.8M SE of Buck Knob -- Mountain at the SE corner of I-55 & Hwy 67) - DeSoto, Mo (Corner of Klondike & Knorpp) - Dittmer, Mo (Although, actually in Cedar Hill, Mo at 7586 Wildflower Ln) - High Ridge, Mo (Gravois (Hwy 30) & Schumacher Rd)

Each site simulcasts these frequencies: - 154.310, 155.355, 155.640, 159.195, 160.095

Each site operates at 65-watts, with an ERP of 192-watts. This means very directional antennas are used, to help better cover that part of the county. 65 goes into 192, times x3.

Here are webpages on the simulcasting system used in Jefferson County, Mo: Link1 - http://mrtmag.com/news/harris_midwest_radio_012005/ Link2 - http://mrtmag.com/mag/radio_simulcast_saturates_missouri/index.html Link3 - http://www.broadcast.harris.com/publicsafety/lmrc/synchrocast.asp Link4 - http://www.harris.com/view_pressrelease.asp?act=lookup&pr_id=1495

• NOTE * When traveling out or away from Jefferson County, these simulcasting frequencies from several of the sites at-once can cause aweful distortion and in the worst case-scenario, cause complete 100% cancellation of the signals. In St Louis City, the distortion/cancellation is very heavy from the High Ridge & Arnold sites mixing together in our radios. One of the few draw-backs of SIMULCASTING.
