primary transmitter at the Fridley water tank and with backup transmitters at that Fridley site and also at the Andover site. This channel is also served by nine additional receivers to improve the talk-back performance from radio users with low power handheld portable radios. The second dispatch channel is the north main dispatch channel (Channel 7, two frequency mobile relay or repeater channel) with a primary transmitter at the Andover site and a backup transmitter at the Anoka County Government Center site. This channel also is equipped with nine additional receivers to improve talk-back coverage from low power handheld portable radios. A third law enforcement channel is the information channel (Channel 3, a two channel mobile relay or repeater channel) with a primary transmitter located at the Bunker site and with a backup transmitter located at the Anoka County Government Center. This channel also has nine additional receivers to improve the talk-back coverage from low power handheld portable radios. A fourth law enforcement channel is the south administrative channel (Channel 5, which is a single frequency simplex channel) with the transmitter and receiver at the Andover site. There is no backup transmitter for this channel and there are no additional receivers associated with this channel. The fifth law enforcement channel is the north administrative channel (Channel 2, which is a single frequency simplex channel) with a primary transmitter at the Anoka County Government Center. There is no backup transmitter and there are no additional receivers associated with this channel. The south main dispatch channel is served by a radio operator 24 hours per day. The north main dispatch channel is served by a radio operator only 16 hours per day from 1100 to 0300. Currently there is no radio dispatch radio operator on this channel from 0300 to 1100. 2.2 SURVEY QUESTIONNAIRE 2.2.1 Construction of the Questionnaire Document Early in the progress ofthis project, a questionnaire was developed and circulated in the fire service and law enforcement communities. The questionnaire was constructed in a way intended to obtain information from the users of the fire and law enforcement two-way radio systems in regard to the performance of those systems. For example, the questionnaire did not explore the issue of congestion by asking a simple question such as, "Is there congestion on the radio channel?" Instead, questions related to congestions were, "During busier hours of busy month, what percentage of the time do you have to wait ten seconds or longer to use the radio channel?" Another question related to congestion is, "During busier hours of busy month do law enforcement officers report fewer car stops and building checks than during other times?" Separate questionnaires were developed for the fire service and for law enforcement. Copies of Ronald Vegemasl Engineering, Inc. -8- Report: Anoka County
