This video details the prototype for a new design of interface.
I can not produce these individually because quality control goes out of the window with this type of construction.
I am very keen to have professionally produced PCB's made, and have these available to buy.
FEATURES:
ZERO noise floor.
Fully adjustable VOX activation.
Visual indication of incoming audio.
RX and TX audio is adjustable from the dials BEFORE the audio transformers.
High quality audio transformers.
MIC GND, SPK GND, PTT GND and PC GND are all completely isolated from each other (Signalink cannot separate MIC, SPK and PTT GND.)
Facility to have PTT rekey timer delay which prevents "Call failed" on older Simoco Tetra terminals.
Built to address real problems.
Interested in Tetra and other Digital modes?
