All audio and control I/O brought out to 3.5mm (1/8") jacks. 12-15vdc power is supplied through a standard 2.1mm coaxial barrel type jack. RS-232 I/O via standard DB-9 female connector.
An Auxiliary Control Relay is included.
This relay is turned on and off using the DTMF keys on your remote radio. Use it to trigger or control anything you like. Route audio or power through the relay.
A high-pass filter in the TX audio to mic input line to reduce hum and PL tones.
Internal trimpots for RX and TX audio level adjustments.
COS or VOX RX Control.
COS greatly reduces drop-out and "falsing" that is sometimes experienced when using VOX RX Control. (Requires COS signal from radio).
All components are mounted on the pc board. No wires!
Available as a kit or fully assembled
High quality components for reliable operation. The double sided (US Made) HQ FR4 Specification) PTH pc board is professionally designed and manufactured with RoHS compliance in mind, silkscreen (white part designator text) and soldermask (green anti-solder coating).
Repeater controller friendly ! Can be connected directly to a multi-port repeater controller. No problems with audio feedback or isolation.
Transceivers with push-pull receive audio (Higher quality radios) e.g. Motorola GM300 and Mitrek must not let one side of the audio line come in contact with ground. Push-Pull audio (class B) Audio line have 2 'hots' If you are not sure call us when you order and we can determine which ever it is.
The audio finals will look something like figure 1 below
