I've downloaded both programs.
Now I've got to dig out that old NEC portable and see what kind of
RS232 port it has. (And see if it still works)!
I noticed the diagrams seem to use a different ground reference.
Yesterday, I looked at the output on the O-scope and it seemed
like the best ground reference was the input signal..?..
I was seeing a +4 & -4 Volt waveform (RS232 serial data format)
using the input line as my ground ref.. weird..
It's going to be a while before I can solder again, but
when I get Chrony data flowing, I'll post the DIY info.
