[amsat-bb] AO-7 mode information

[Jim White <jim@xxxxxxxxxxxxxxxxxxxxx>]

Here is some information from Jan about how the modes originally 
worked.  Not enough info yet to determine if they are still this way.
Also, a couple of 70cm TLM reports I've see show only three values in each 
row.  At present that's a mystery.  More 70cm TLM would be appreciated.

>Mode D:  All off except 70 cm beacon CAN be on in this mode.
