Simplex Repeater Maker H250 Handset for Military Manpack Radios

Simplex Repeater Maker H250 Handset for Military Manpack Radios


The SVR-1-HS1 can be connected to many military man pack radios to create a simplex store and forward repeater. When the SVR-1-HS1 sees a busy indication from the radio or detects VOX it will start recording the received audio. When the busy indication or VOX goes away for a programmed amount of time, the SVR-1-HS1 will key the radio and retransmit the recorded audio. The following are applications for the SVR-1-HS1 as a simplex repeater:

• Create a low-cost simplex vehicular repeater to increase portable radio coverage when the user is out of his or her vehicle.

• Expand radio coverage into remote locations, tunnels, buildings (hospitals, campuses, etc), downtown areas and more.

• Evaluate potential radio site or coverage problems by connecting the SVR-1 to a mobile radio. A technician can then drive through the desired coverage area, key up and transmit voice, unkey and listen to the repeated audio quality.

Announcement Mode:

The SVR-1-HS1 can be programmed to repeat the last received audio message continuously at programmable intervals, applications include:

• Broadcasts for road or weather conditions

• Aviation authority broadcasts for pilot information (ATIS — Automatic Terminal Information Service)


  • Low-cost alternative for expanding radio coverage
  • Up to 180 seconds of record time for message playback
  • COR or VOX operation
  • The H250 handset derives power from the center pin on the U-329 connector on many newer Manpack Radios
  • To install on a Manpack Radio twist off existing handset & twist on the HS1/HS1G product in its place
  • 3 year warranty


Midian's SVR-1-HS1 is ideal for extending coverage into areas with poor reception, evaluating potential repeater sites and continuously rebroadcasting voice messages.


Midian's SVR-1-HS1 is available with many pre-made cables for many manpack radios using the U-329 connector such as the PRC1077, PRC77, PRC155, PRC25 and more. Different connector configurations are also available for other manpack radios. View compatible manpack radios.
