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.
