PSK31 interface. |
This interface was built to allow isolated connections between both
the radio transceiver and a computer for PSK31 usage. This is really no different to other Computer Assisted Transceiver (CAT)
designs that use an optocoupler for the PTT and audio transformers for receive and transmit audio.
This provides complete isolation - no ground loops, etc.
So, you may find this type of interface also suitable for PC-ALE, Digipan, HamScope and the like. I was lucky that Paul,
VK5AB, had designed a surface mount pcb that is small and neat!
