The microphone audio is completely isolated from all other grounds and transformer coupled.
he Speakr audio is completely isolated from all other grounds.
The sound card audio signals are isolated using three audio transformers.
The Radio PTT are isolated using, DPDT relays.
CW and FSK Output are opto-isolated.

The relays provide adequate current and voltage capability to switch tube rigs.
