2ABEE125MIIVMODERNIZED VHF MASTR II BASE STATION

MASTR II REPEATER STATION SOUTHERN MAINE COMMUNICATIONS NARROWBAND UPGRADE INSTALLATION AND USERS MANUAL DECEMBER 2012 INTRODUCTION General Electric MASTR II Repeater Stations have proven exceptionally reliable and capable of superior performance when properly maintained. In order to extend the service life of existing Commercial and Public Safety MASTR II infrastructure, Southern Maine Communications Service has developed an Upgrade Path which allows existing station equipment to continue in service after January of 2013 by complying with Narrowband (12.5 kHz) channel parameters and being recertified as type accepted. DESCRIPTION Stations selected for upgrade to Narrowband by Southern Maine Communications Service are Continuous Duty Repeater Stations in either the VHF 150.8 – 162.0125 MHz or UHF 450-470 MHz frequency ranges with adjustable RF output power of 22 to 110 watts in VHF or 30 to 100 watts in UHF. SAFETY CONSIDERATIONS Stations are to be installed by experienced technicians familiar with Land Mobile radio equipment, OSHA safety procedures regarding exposure to Electromagnetic Energy (EME) and FCC safety procedures regarding exposure to Radio Frequency Energy (RF). INSTALLATION Stations are to be installed indoors in suitable permanent locations with permanent structure-mounted antenna equipment and appropriate antenna filtering equipment and cables engineered to meet the licensing and operational needs of the site, including but not limited to: duplexers, tuned cavity filters, isolators, and suitable coaxial cables and connectors. WARNING STATEMENT The SMC 125MIIV has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits for Occupational Use/Controlled Exposure Environment. In addition, it complies with the following Standards and Guidelines:  47 C.F.R 2.1091 and 2.1093.  KDB Guidance Publication 447498.  The antennas for this device are designed to be mounted on permanent outdoor structures which usually provide a separation distance greater than 263 cm (104 inches) for a typical installation consisting a 3 dBi antenna and a 100% duty cycle as stated in the RF exposure report. RF exposure is usually also addressed at the time of licensing.  This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure limits of passengers and bystanders by maintaining the minimum separation distance shown below.  Failure to observe these restrictions will result in exceeding the FCC RF exposure limits.  • Unsafe Radiation Distance • SMC 125MIIV 8.64 Feet (2.64m) MOUNTING Stations may be 19” Rack Mounted or Cabinet Mounted as indicated by the parameters of each application. Station should be appropriately grounded to the rack or cabinet. POWER SUPPLY Stations are powered by 13.8 volts DC from an appropriate power supply which may be cabinet or rack mounted as determined by application. 13.8 volts DC is provided to the Station Shelf via the 9 pin .062 Molex plug P9 (pin 1 Red +) (pin 4 Black -) and should be fused at 5A, and to the RF Power Amplifier via the #8 flying leads (Red +) (Black -) fused at 30A. REPEATER STATION CONTROL Repeater control functions are managed by appropriate equipment as indicated by the parameters of each application. Single user systems may be set up using original GE MASTR II Channel Guard Decode boards (19D432500G1) (installed on System Board A901- P908 & P909) and encode boards (19C331044G1) (installed in exciter shelf) with Audio Board (19A129924G2) (installed in J1206) and Repeater Control Board (PL19D417198G2) (installed in J1207) of the Station Control Shelf. Multiple user systems may be set up using after-market repeater controllers such as provided by Zetron and Communications Specialists. These products should be installed into the MASTR II Station Control Shelf as specified by the controller manufacturer. STATION CONTROLS POWER SUPPLY CONNECTIONS Local Volume System Squelch

SMC MASTR II NARROWBAND UPGRADE VHF 19D423249G2 150.8 to 162.0125 MHz Phase Lock Loop Exciter The Exciter is a Crystal Controlled (Crystal Frequency x 12) Frequency Modulated, Phase Locked Loop. RF Carrier Stability of +/-0.0002% over the 150.8 to 162.0125 MHz Range of the Exciter is maintained by a phase detector that compares the 3 rd harmonic output of the Temperature Compensated (0 to +55 centigrade) Frequency Modulated Integrated Circuit Oscillator Module (2C-FM- ICOM) with the output of the Voltage Controlled Oscillator and makes instantaneous phase and frequency corrections with error voltage applied through a filter/varactor circuit. The 2C-FM-ICOM is modulated by the output of the Audio Processor Circuit, producing Direct FM equivalent to the output of the audio processor. The Audio Processor Circuit (19C321542G2) provides approximately 24dB gain along with pre- emphasis, limiting, and post-limit filtering. The MOD ADJ control (R104) on the exciter board is set for a deviation of 2.0 kHz deviation. The CG MOD ADJ control (R103) is set for .375 kHz deviation. Total system deviation is set at or below 2.5 kHz. The modulated output of the 2C-FM-ICOM is applied to the Bandpass Filter (19B226748G2) which passes only the 3 rd harmonic, which is amplified and fed to the Phase Detector (U101) for comparison with the divided and filtered output of the Voltage Controlled Oscillator. Any differential voltage is amplified and used to correct VCO frequency or phase error. The amplified differential voltage used to control and correct the VCO is monitored by a Lock Detector circuit which removes the 10V control voltage from the RF amplifier of the exciter if the VCO goes out of lock. With the VCO in lock and 10V PTT voltage present, the FM modulated Carrier signal is amplified and delivered at a minimum level of 250 milliwatts to output jack J101.

SMC MASTR II NARROWBAND UPGRADE PLL TRANSMITTER ALIGNMENT (VHF) REQUIRED TEST EQUIPMENT: *Communications service monitor *RF Wattmeter and 50 ohm load (preferably Bird model 6154 or equivalent) *Audio tone generator PRELIMINARY SET-UP AND TUNING: 1.Turn down R8 (fully counter-clockwise) and R6 (fully clockwise) on the Transmit Power Amplifier. 2. Turn down R103 and R104 (fully counter-clockwise) on the Exciter. TX TUNING PROCEDURE: (EXCITER 190423249G2) 1. Connect the 50 ohm load to J101 of exciter. Key transmitter and verify that the “lock” LED illuminates. If not, using a DC voltmeter across TP101 and A-, adjust L101 for a voltage of 5VDC with the transmitter keyed. Remove voltmeter and keeping the transmitter keyed, adjust XY101 (transmit ICOM) with the communications service monitor to transmit operating frequency. 2. Turn modulation adjust R104 and CG modulation adjust R103 pots all the way down (counter-clockwise). Using the audio tone generator, inject a 1000 Hz tone with a level of 1VAC RMS between P902 pin 6 and P902 pin 4 on exciter. Key transmitter and adjust R104 (mod) to indicate 2.0 kHz of deviation on the communications monitor. Unkey transmitter, remove audio tone generator. 3. For units with CG encode, connect CTCSS encoder, key transmitter, and adjust R103 (CG) to indicate a deviation of 375 kHz on the communications service monitor. Unkey transmitter. 4. Disconnect 50 ohm load. (POWER AMPLIFIER 110W) 1. Connect RF wattmeter and 50 ohm load to TX antenna port of the power amplifier. 2. Key transmitter and adjust R6 for a wattmeter reading of no more than 125 watts and adjust C2 and C4 repeatedly to obtain maximum RF output power. 3. Reset R6 to a power level of 125 watts. 4. Set R8 for rated power of 110 watts. 5. Unkey transmitter, disconnect RF wattmeter and load.
