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. The SVR-1
enables users to create low-cost vehicular repeaters or expand radio coverage into poor coverage areas.

PRODUCT PROGRAMMING
Midian’s SVR-1-IC1 is programmed via Midian’s KL-4F programming interface and the MPS software. Please
reference the 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.
After entering the parameters, save the file by going to File - Save As. Enter the file name in the File Name block
and click Save. Saving the file will allow for quick and easy reprogramming of units.
Programming: Plug the board onto the IC1 connector on the KL-4F. Press and hold the power button on the KL-
4F and click “Program Unit” in the MPS software. The ACK LED on the KL-4F will faintly flash if programmed
successfully.
Reading: Plug the board onto the IC1 connector on the KL-4F. Press and hold the power button on the KL-4F
and click “Read Unit” in the MPS software.
Note: Upon power up the unit will be awake for 15 seconds before going into Power Save mode.
After programming or reading the SVR-1 turn off the unit for 3 seconds and then turn back on.
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.
VOX Settings > Sensitivity: This is a threshold detection based on the energy level in the audio.
VOX Settings > Attack Time: This sets the minimum time before the unit will detect VOX based on the sensitivity
setting.
VOX Settings > Decay Time: This sets the time before the unit will drop the VOX detection. Be certain to set this
long enough so that you do not have drop outs between words or on brief pauses.
Beep Options > Power Up: Enables a short beep sequence that takes place immediately after power-up.
Beep Options > Error: This beep may be triggered by any input event if programmed to do so. For example, if a
long press on the Mode Input is not assigned to a function, it may be configured to generate the error beep.
Beep Options > Mode: When using a switch to enable/disable the SVR, a medium tone followed by a high tone
will sound indicating repeat mode is enabled. When pressed again a medium tone followed by a low tone will
sound indicating repeat mode is disabled.
Beep Options > Go Ahead: Not currently used.
Beep Options > Wake Up Beep: Enables a short beep to be sent over the air immediately after PTT is pressed.
Enabling this beep is recommended when the 'Wake on VOX' feature is used. This may also be used to get the
attention of the party receiving a call.
Beep Options > Courtesy Beep: If selected, once the unit is done retransmitting the recorded audio it will
generate a courtesy tone to let others know it is done retransmitting.
Beep Options > Enable Side Tone Pin: Must be checked to get mode beeps.
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.
Common PTT: Check this box if PTT In and PTT Out are connected to the same point.
PTT Cancels Store/Retransmit: If checked and the PTT is pressed during store/retransmit the unit will not
retransmit the incoming transmission.
Number of Retransmits: This sets how many times the unit will retransmit the last recorded audio clip.
Retransmit Interval: This sets the time interval between the retransmits set in the Number of Retransmits field.
7
PTT > Active Polarity: This sets whether the unit looks for an active low or active high to cancel a
store/retransmit.
PTT > Debounce: If checked the unit will require a continuous active state for 30 msec before accepting the PTT.
Mode > Type: Select whether the switch is Momentary or Latched. In this case it should be Momentary.
Mode > Active Polarity: Select the active polarity of the mode switch. In this case it should be Low.
Mode > Debounce: If checked the unit will require a continuous active state for 30 msec before accepting the
mode change.
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.
PTT > Active Polarity: This sets the polarity necessary for the unit’s PTT output to key the radio.
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.
Trunking Delay Input > Debounce: If checked the unit will require a continuous active state for 30 msec before
accepting the channel acquisition.
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.
Playback > Playback Level: Not used in this application.
Playback > Transmit Level: This controls the audio level when a stored voice message is retransmitted over the
air. If the transmit level is too low or too loud, adjust this level accordingly.
