Yes-- Thanks Bill.  I have various loop converters to both RS232 and
TTL so should be set there.

Most of the work here will be on the radio side--  I have evolved
the HF station for mostly software-based modes and also have to use
separate receive antennas (various loops) as the noise floor is otherwise
intolerable here.  So, I am working on an RF sensed T/R switch that will
allow receiving on a loop but TX on any of my various vertical and wire
antennas and then I can dedicate a TS-440, IC-7300 or some other to RTTY.

Fortunately, I just retired so I _think_ I will have more time for this
stuff :-)
