Page 3: General Information
GENERAL INFORMATION Midian’s SVR-1 is a simplex repeater maker that can be installed into a mobile or portable radio. The SVR-1 detects COR or VOX from an incoming transmission and records the incoming audio (up to 3 minutes). When the COR or VOX is no longer detected the SVR-1 keys the radio and retransmits the recorded audio. -
Page 4: Product Programming
KL-4F manual for setup instructions of the MPS software and the KL-4F hardware. From the product selection screen in the software, select the SVR-1-IC1 from the list and click OK. Set the parameters of the software to fit the application. If any clarifications on a feature are required, move the mouse cursor over the feature name until the question mark appears and right click, a definition of the feature will be shown. - Page 5 Store on COR/Store on VOX: Select the appropriate method that the unit should use to start recording incoming audio. COR Hold-Up Time This sets the amount of times after a loss of COR or VOX that the unit will wait until it retransmits the recorded audio.
- Page 6 Key-Up Delay: This sets the amount of time the unit waits after keying the base station radio before it starts to retransmit the recorded audio. Trunking Delay Enable: Check this box if using a trunking system. This will cause the unit to hold off regenerating the recorded audio until it has received a channel acquisition acknowledgement from the base station radio.

- Page 8 COR > Active Polarity: This sets whether the unit looks for an active low or active high to start recording the received audio. COR > Debounce: If checked the unit will require a continuous active state for 30 msec before accepting the COR.
- Page 9 Audio Enable > Active Polarity: This sets the polarity necessary for the unit to enable the speaker of the radio to pass beeps. Trunking Delay Input > Active Polarity: This sets whether the unit needs an active low or active high indication from the radio to indicate a trunked channel has been established.
- Page 10 Tones > Beep Volume: Adjust the slider for the desired beep volume. This level is expressed as a percentage of max voice audio level. Tones > Over-The-Air-Signal Modulation: Adjust the slider for the desired beep volume. This level is expressed as a percentage of max voice audio level.
- Page 11 SVR uses programmable gain amplifiers to accomplish this. Determining the gain settings for these amplifiers is an involved process, so Midian simplified this process by developing an algorithm that requires the technician to make only four voltage measurements. From these four measurements, all of the many internal settings are determined.

Page 13: Hardware Installation
HARDWARE INSTALLATION Be certain to follow standard anti-static procedures when handling any of Midian’s products. Icom F-3: Remove W2 to open the radio’s TX path, W10 to open the radio’s RX path, and W1 to open the radio’s PTT path. - Page 14 Icom F-320, F-420, F-520, F-620: Open jumper A to open the radio’s TX path, jumper B to open the radio’s RX path, and jumper C to open the radio’s PTT path. The unit plugs into the options connector located on the main board. Icom F-1020, F-2020: Open jumper MIC to open the radio’s TX path, jumper AFO to open the radio’s RX path, and jumper PTT to open the radio’s PTT path.
