I need a couple of CIV interfaces for WriteLog. It is important that I be able
to key the radio via the
DTR port. Most of the circuits I see, as well as the commonly available simple
interfaces, get their
power from the DTR line, so won't work. What simple circuits are available to
solve this problem? My
need is for a single computer serial port to a single radio. I would really
like to find something that I
can build with a couple of transistors, resistors, and diodes.
