4-way PTT splitter
This is simply 4-way analog splitter. Designed for no-delay PTT switching. From one input to 4 outputs. You can split PTT signal to 4 independent devices. This device also protects your TRX PTT output from external accessories. There are optocoupler isolators between PTT input and all four PTT outputs.
