Simple PC morse interface for sending CW. This unit is simple, inexpensive and isolates your rig and PC optically so there are no ground loops or other nasties. The output of the 4N25 optoisolator chip is intended to sink only low currents and voltages around 30V max. This is sufficient for the CW input of many modern transceivers, but check the manual. If more current/voltage handling capacity is required the 4N25 output can be used to switch a custom higher current interface. Music "Magic_host" by danosongs.com
