The Base Tech II Base Repeater is comprised of separate modules all housed within one 2RU equipment cabinet. The receiver, transmitter, and PA unit are each enclosed within their own die-cast housing. Each one is then mounted directly on the large upper heatsink. A microprocessor-controlled interface module controls the channel selection, LCD Display, timers, interfaces, and signaling features. The RF power output is 25 — 110 watts, depending on the model, and rated for continuous duty. The CTCSS module supports all EIA tones. All tones and different encode and decode tones can be set on a per channel basis during radio programming. Attention The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 6 meters from all persons during normal operation. The peak conducted output power at each antenna terminal must not exceed 250 Watts and the peak radiated output power must not exceed 1000 Watts EIPR. Users and installers must ensure that FCC requirements for satisfying RF exposure compliance are met. (See FCC Rules Part 1, Sections 1307 and 1310) Features o Simplex or two frequency Duplex operation o EEPROM programmable with a PC computer o 99 programmable multi-mode channels o Full dot matrix LCD o Front-facing speaker o Transmit time limiter to prevent channel jamming o TX and RX encryption optional o Two channel scanning modes o 5-Tone encoder and decoder plu…

Align the BPF-101 and BPF-102 to obtain the maximum sensitivity. For better alignment, if you have spectrum analyzer and tracking generator, connect the tracking generator to the Rx antenna connector and pick up the output signal from J101 to connect spectrum analyzer. Align the BPF-101 and BPF-102 to cover the desired bandwidth of receiving frequencies. 2) FVR101 alignment This is to adjust the tight squelch level. 3) VCO alignment The VCO has been aligned at the factory to cover full bandwidth. However, if you need to re-adjust the VCO when you repair, set the VCO voltage at 10.5V by L303 at the highest band frequency. FVR101L303 BPF102 BPF101 Preparation 71-4110 © Midland Radio Corporation 5 TRANSMITTER PART 1) FVR201 alignment This potentiometer determines the modulation level. Carefully align FVR201 to obtain flat deviation from the lowest to the highest frequency installed in the transmitter. 2) FVR202 alignment This potentiometer determines the low frequency (below 300Hz) deviation. When CTCSS or DCS are used, it is necessary to align FVR202 to have enough deviation at low frequency. 3) FVR203 alignment FVR203 sets the maximum deviation, normally set at 5KHz. 2KHz or 2.5KHz deviation, for narrow spacing, can be selected with the programming software. 4) FVR204 alignment FVR204 adjusts the output power supplied to the transmitter. 5) VCO alignment The VCO has already been aligned at the factory, however if you need to re-adjust, set the VCO voltage to 10.5V at the highest band frequency. FVR204 FVR203 FVR202FVR201 Preparation 71-4110 © Midland Radio Corporation 6 POWER AMPLIFIER PART 1) With APC off, obtain maximum power reading by adjusting FVC502, 503, 504, 505, and 506. 2) FVR501 Adjust FVR501 for minimum reverse power when the antenna is terminated with 50 ohms load. 3) FVR502 FVR502 sets the point where reverse power is detected. 4) FVR503 FVR503 sets the point where a low-power-alarm is triggered. 5) FVR504 FVR504 sets the maximum power from the power module, however, do not exceed 110 watts +/- 2%. 6) FVR505 FVR505 sets the high-temperature protection level. 7) FVR506 FVR506 sets the PA bias to the correct current. This is a factory setting and does not need adjustment in normal alignment practice. Service note: Touching the gate of a FET power device can cause damage to the device. LOGIC PART 1) FVR1 alignment Set FVR1 to obtain 0dBm output into 600 ohms. 2) FVR2 alignment Adjust FVR2 for flat deviation level when used for a repeater. 3) FVR3 alignment FVR3 adjusts the power level indicator on the LCD. 8) FVC1 alignment Use FVC1 to shift the CPU clock frequency when necessary. A beat interference sometimes happens at certain frequency. In such case, shifting the CPU clock frequency may eliminate the interference. Preparation 71-4110 © Midland Radio Corporation 7 FVR1 FVR2FVC1 FVR3 FRONT CONTROL PANEL PART 1) VR401 alignment This is a volume controller. 2) VR402 alignment This is a squelch level controller. 3) FVR401 alignment Use FVR401 to set the HI-POWER-LEVEL of the Tx output power. 4) FVR402 alignment Use FVR402 to set the LO-POWER-LEVEL of the Tx output power. 5) FVR403 alignment This is to set the contrast of the LCD back light.
