Case:One piece extruded aluminium 1 Narrowband operation is special order Page 4 SVR-200 Service Manual Functional Description Generally, vehicular repeaters are used as mobile extenders in cross-band operation: the link is VHF/UHF/800 MHz simplex and the mobile is Lo-band, VHF, UHF or trunking. In-band operation is possible, but care must be taken to prevent interference between the mobile's higher power transmitter and the repeater receiver. Proper frequency selection and antenna placement are important even in cross-band operation, but especially for inband use. The use of low power pre-selector cavities may be placed in line with the repeater antenna cable since it is simplex and low power. Important Note The SVR-200 operates on simplex frequencies; part of the multi-vehicle format dictates that all of the SVR-200s must be able to monitor all link traffic on site and be able to determine if a handheld is transmitting, or if other repeaters are transmitting. The handhelds must transmit CTCSS, but should be carrier squelch receive. The handhelds should not use CTCSS decode if the repeater is utilizing the multi-vehicle format, as this will interfere with the priority sampling which is essential for multi-vehicle operation. Also, the handhelds would have to have different encode and decode tones in order for the repeater to be able to tell the difference between handhelds and other repeaters, so the handhelds would not be able to hear each other. The repeaters should not transmit CTCSS unless used only in a single vehicle environment. W…

Page 8 SVR-200 Service Manual Alignment VHF Before aligning the SVR-200, ensure that the mobile radio is aligned per the manufacturer’s service procedure; Ensure that the SVR-200 is properly programmed and the jumpers are set per the previous section. In order to properly align the SVR-200, you will need two service monitors and the mobile radio that the repeater will be installed with. Refer to figure 1 for alignment points. Dis-assemble the repeater by removing the two cap screws on the rear panel and the phillips screw on the bottom. Slide the main circuit board out of the housing with the rear panel attached. Connect one service monitor to the SVR-200 BNC jack and the other to the mobile antenna jack. Connect the cable from the mobile radio to the SVR-200; turn on the mobile and activate the SVR-200. Adjust the repeater squelch control (RV9) so that the repeater COR led is off. Adjust the mobile so that the audio is squelched. SVR-200 VHF Transmitter 1.Transmitter Output: Short J3 and adjust RV10 for maximum. Adjust C60, C61 and C56 on the RF board for maximum RF power output and minimum spurious output. Adjust RV10 250 mW. The SVR-200 case is integral to the voltage regulator heat sink and the unit should not transmit at full power when removed from the case for extended periods. 2.Transmitter frequency: Adjust the TCXO on the RF board for the transmit frequency. 3.Maximum deviation/lock tone deviation: Adjust RV7 (lock tone deviation) for maximum. If the SVR-200 is programmed for sub-audible encode, adjust RV6 (CTCSS) for minimum. Adjust RV8 (repeater deviation) for 95% deviation. Adjust RV7 for 60% deviation. Remove J3. 4.Mobile COR: Measure the voltage at pin 7 of SVR-200 main connector P1 and record. Set the mobile service monitor for the mobile receive frequency, 1mV RF output and CTCSS modulation of 15%. Measure the voltage again at pin 7 and record. Turn the mobile service monitor off and adjust RV1 on the SVR-200 main board for the halfway point between the two voltage readings as read at pin 3 of U1. 5.RX audio sensitivity/CTCSS deviation: Set the service monitor connected to the mobile for the mobile receive frequency and 1mV RF output. Modulate the signal generator with a 1kHz tone at 60% deviation and CTCSS tone at 15% deviation. Ensure that the SVR-200 mobile COR and repeater PTT LED’s are on. Adjust RV5 on the SVR-200 main board for 60% deviation as read on the service monitor connected to the SVR-200. If programmed for sub-audible encode, remove the 1kHz tone deviation from the mobile service monitor and adjust RV6 on the SVR-200 main board for 15% deviation. Turn the RF output from the mobile service monitor off and ensure that the SVR-200 mobile COR and repeater PTT LEDs are off. 6.Local mic repeat: If the SVR-200 is programmed for local mic repeat, key the mobile local mic and inject an audio signal into the local mic to produce 60% deviation on the service monitor connected to the mobile. Confirm that the SVR-200 repeater PTT LED is on; adjust RV2 for 60% deviation as read on the service monitor connected to the SVR-200. Unkey the mobile radio. 7. RF power out: Short J3 and adjust RV10 for the operating power output. Open J3. Page 9 SVR-200 Service Manual Figure 1 VHF Receiver 1.Receiver front end: Connect a DC voltmeter to TP1 on the SVR-200 main board. Set the service monitor connected to the SVR-200 to the generate mode, receive frequency with a 1kHz tone and 60% deviation. Adjust the RF output of the monitor for a 1VDC reading at TP1. Adjust L1-L4 on the RF board for a maximum reading at TP1. 2.Repeater squelch: Adjust the service monitor RF output for .5μV. Adjust RV9 on the SVR-200 main board so the repeater COR LED is just on. Decrease the service monitor RF output to .3μV and ensure that the repeater COR LED is off. 3.Transmit audio output: Adjust the service monitor RF output for 1mV. Turn the CTCSS modulation on and set for 15% deviation. Confirm that the repeater COR, CTCSS and mobile PTT LED’s are on. Adjust RV3 on the SVR-200 main board for 60% deviation as read on the service monitor connected to the mobile radio. 4.Local Rx audio: Connect an 8 ohm speaker to P4 and set RV4 for the desired listening level. Turn off the CTCSS modulation of the service monitor connected to the SVR-200. Confirm that the repeater CTCSS and mobile PTT LED’s are off. 5.Lock Tone Decode: Change the 1kHz tone modulation to the lock tone frequency. Confirm that the PRI LED goes off after approximately .5 seconds.
