H. Home button: A home button shall force the mobile radio to a pre-designated channel.I. Channels: Radios and associated control heads shall be capable of any combination of 64channels/talk groups (minimum, not including talkaround channels using a switch or button),up to 64 digital conventional systems, and sixteen digital systems (minimum).J. Channels: Radios and associated control heads shall be capable of any combination of 64analog conventional or digital conventional channels (if applicable) not including talkaroundchannels using a switch or button.K. Radios appropriate for use on a motorcycle shall be available.L. Radio shall be capable of Project 25 Phase I digital operation.M. Radio shall be capable of digital encryption as described elsewhere in this specification.Mobile Radio Features (Public Works / Utilities)Mobile radio equipment shall be equipped with the following features:A. Mobile radio shall be front mount unless specified otherwise.B. The radio shall be equipped with a control head with an eight-character alphanumeric displayto allow the user to assign a descriptive name to each operating condition. Control headdisplays shall be clearly labeled and visible in bright sunlight, with variable brightness. Thedisplay shall be either backlit or vacuum florescent for night visibility.C. Radios shall be capable of the following features (some features are described later in thissection):Priority ScanCaller ID DisplayEmergency AlarmPTT-IDD. Priority Scan: Units will provide conventional priority scanning with the followingoperational requirements:1. Capable of priority scanning user-selected conventional channels. Radios shall becapable of prioritizing the selected channel, and of simultaneous scanning a mix of up to48 other conventional channels.2. Capable of instantaneously (in under 300 ms) locking-out up 47 active channels from thescan list by pressing a single switch, without deleting it from the user-defined scan list.The channel shall be "undeleted" by turning cycling the power, or by selecting a differentchannel.3. In priority scan mode, the display shall continue to show the selected channel (thechannel that will be transmitted upon) unless another active channel is being received.E. Conventional talkaround: A button on the control head assembly shall enable the talkaroundfunction on any selected conventional repeater channel, using the receive CTCSS code as thetransmit CTCSS code. Talkaround should operate when in scan mode.F. Home button: A home button shall force the mobile radio to a pre-designated channel.City of San Luis Obispo 54 Radio System Upgrade TECHNICAL APPENDIX
G. 48 Channels: Radios and the associated control head shall be capable of a minimum 48-channel operation (this does not include the talkaround channels using a front panel switch).UHF Mobile Radio Technical SpecificationsTable 15A. – Mobile Radio Transmitter Technical Specification - PoliceFrequency range450 to 470 MHzFrequency spread (min.), no degradation 20 MHzProgrammable channel steps12.5 kHzPower output, vehicular (EIA Intermittent) 40 WSpurious and harmonic emissions-70 dBcTable 15B. – Mobile Radio Receiver Technical Specification - PoliceFrequency range450 to 470 MHzFrequency spread (min.), no degradation 20 MHzChannel steps12.5 kHzAnalog Sensitivity, 12 dB SINAD-116 dBmDigital Sensitivity, 5% BER (DAQ 3.0) -116 dBmSelectivity, EIA, @ 25 kHz bandwidth (analog) -80 dB@ 12.5 kHz bandwidth (analog) -70 dBIntermodulation immunity-80 dBSpurious and image rejection-80 dBSpeaker input power, (minimum)8 WTable 16A. –Mobile Radio Transmitter Technical Specification – Public Works/UtilitiesFrequency range450 to 470 MHzFrequency spread (min.), no degradation 20 MHzProgrammable channel steps12.5 kHzPower output, vehicular (EIA Intermittent) 40 WSpurious and harmonic emissions-70 dBcTable 16B. –Mobile Radio Receiver Technical Specification – Public Works/UtilitiesFrequency range450 to 470 MHzFrequency spread (min.), no degradation20 MHzChannel steps12.5 kHzAnalog Sensitivity, 12 dB SINAD-116 dBmDigital Sensitivity, 5% BER (DAQ 3.0)-116 dBmSelectivity, EIA, @ 25 kHz bandwidth (analog) -75 dB@ 12.5 kHz bandwidth (analog) -65 dBIntermodulation immunity-75 dBSpurious and image rejection-70 dBSpeaker input power, (minimum)4 WCity of San Luis Obispo 55 Radio System Upgrade TECHNICAL APPENDIX
