Midian's PR-10i is a simplex store and forward repeater (aka simplexor or parrot) and paging regenerator that supports regeneration of both tone and voice similar to the discontinued Zetron Model 19. Ideal for extending coverage into areas with poor reception, evaluating potential repeater sites and continuously rebroadcasting voice messages.
Simplex Repeater Mode:
The PR-10i can be connected to a simplex mobile or base station to create a simplex store and forward repeater. When the PR-10i sees a busy indication from the connected radio it will start recording the received audio. When the busy indication goes away for a programmed amount of time, the PR-10i will key the radio and retransmit the recorded audio. The following are applications for the PR-10i as a simplex repeater:
- 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 PR-10i 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.
Selective Repeat Mode:
The PR-10i has an integrated decoder that can be programmed to decode 2-Tone, with an option for DTMF, 5-Tone or Pulse Tone (1500 Hz or 2805 Hz for HEAR Systems). When the tone decoder decodes the programmed sequence(s) it will give a validate output to the PR-10. The validate confirms that the PR-10i should repeat the incoming audio. The tones will also be regenerated. The following are applications for the PR-10i as a selective simplex repeater:
- Regenerate 2-tone or DTMF (optional) pages for fire departments into remote areas or buildings with poor coverage.
- Regenerate Pulse Tone (optional) pages from ambulances in remote areas with poor coverage to hospitals (HEAR Systems).
Announcement Mode:
The PR-10i 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)
The PR-10i can easily be connected to many mobile radios using the rear accessory connector. Midian also offers a number of pre-made cables for many popular radios.
