After posting this note, I see that Mike, DK3WN has already done an AO-7 
RTTY decoder program, available at 

You may need to download is library of ActiveX (.ocx) files from 
http://www.dk3wn.info/files/ocx.zip and unzip it into your 
..\windows\system32\ directory.

Then you may need to (I did) update your Microsoft VB6 Runtime files 
(available from Mike at http://www.dk3wn.info/files/vbrun60sp3.EXE).

It was good to see the detailed TLM from an old friend! One of my first 
AMSAT tasks was to convert calibration data obtained during thermal vac 
testing into the the CW & RTTY TLM equations. I urge all of you 
interested in the early days of AO-7 to read AMSAT-Newsletter-1974.pdf 
<http://www.ka9q.net/AMSAT-Newsletter-1974.pdf> !
