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
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
