OK guys, I thought I had this all figured out at one point. But, as I review things before cutting wires and soldering in new ones I find some confusion. The drawing I can find in my emails archive shows jumping pins 2 and 7 together to put the polar relay coils in series. But 2 and 7 are one of the coils.
So is there another version of the drawing floating around?
Perhaps in RTTY Journal archives? The one I have is black lines
on white back ground. I thought someone had sent me a white line
on black as well, but I can't find it in my email archives. Can't
in the on-line archives either. So either it was emailed direct
and I accidentally deleted it, or I dreamed seeing it.

John,A while back someone (and I cannot remember whom, because he deserves the credit.) Mentioned that a polar relay can be driven directly by an RS-232 output. Think about it, it is really a polar signal.I am kicking myself because I never thought of something so obvious.Tom N3CRK
