Technical Information
MAIN RECIEVER This site is located in the SW corner of the city. The antennas at this site are a Diamond dual band vertical antenna and a Sinclair 210C4 antenna. They are connected through a voting system to enable a better RX coverage. The radio equipment consists of 2 Mitrek radios.
MAIN TRANSMITTER (Above Pic) The main transmitter is located in the NW corner of the city. It is on a 30 foot using a Sinclair 210C4 antenna. The RF equipment includes a GE Master II VHF transmitter with 100W Micor Amp, a scanning UHF receiver unit. The telephone line is installed at this location with a dumb autopatch. All UHF signals transmitted by all three other sites are received at this location and retransmitted out on 145.210. We are using Sinclair duplexers in this part of the system.
The IRLP node is located at the transmitter location. It is coupled directly with the VHF transmitter to ensure clean audio. VOICEMAIL/NORTH END This site is located in the north end of the city. The antennas are on a 30 foot Delhi tower. The RF equipment for the site consists of a GE Master II and a Motorola Mitrek. This is connected to a Cushcraft 6 element Yagi. The voicemail is a DCI-100 running on a 386SX computer.
The east side reciever is the most recent addition to the system. It is located in the central east part of Saskatoon. The RF equipment is a GE Exec II radio with a VHF reciever and UHF transmitter. All the identification is done in voice with the exception of the intermittent CW id on the transmitter. Digital audio delay boards may be added to the system for the purpose of DTMF muting and a more pleasant sounding audio with the elimination of the squelch crashes. As time goes on the plans are to add more receiver sites throughout the rest of the city to further enhance the handheld range.
