Description
The SFR can be used on an existing LMRS single frequency license, without having to go to the expense of a specific repeater license (assuming adherence to the license parameters).
A duplexer is not required, so you are not bound by the bandwidth of the duplexer. This gives you frequency agility. No duplexer, no insertion loss either.
Ease of set-up.
A very cost effective DMR Repeater Solution.
Increased coverage on your current license, even at low power limits.
Can be used as a Mobile or Base Transceiver with the use of a microphone, or when in repeater mode – by using a handheld unit in close proximity as a ‘remote handheld device’.
Relays other DMR radio’s encryption, for maximum security.
A talk-around function is not required when the repeater is out of range, making operation much simpler. The DMR radios will simply talk directly to each other instead (without having to separately activate talk-around or change the channel – like you would have to do with a conventional duplex repeater).
Operation:
The SFR should be used with DMR radios capable of Tier II DMO dual slot trunk (sometimes referred to as pseudo trunk). DMO trunk radios will use whichever time slot is available.
DMR still uses a form of FM transmission, and with FM – the strongest transmit signal generally owns the channel. So the receiving radio will hear whichever signal is strongest, be it from the SFR or from the other radio.
