Hi all, A few weeks ago I asked for advice about how to help me achieve FSK with my Signalink. Before I had to switch between the Signalink and a W3YY interface, with the audio out from my FT-950 goi
I do have one very basic question. What exactly is this transistor doing? Why do we need it? Why can't I just plug the TxD lead directly into the Signalink? Serial port signals are bipolar +V/-V. The
Ah! Thank you Joe. I now see what the transistor is doing. That also explains why a great many of my earlier experiments didn't work! 73, -- /*/-=[Michael / KT5MR]-=/*/ ______________________________
