I saw on one of the NASA announcements that the snarffled 70cm antenna would mean no commanding of the bird. (This was probably before it was realized that that receive actually seems to work). But the question I have is whether there IS some commanding of the bird possible. I guess you have to be able to turn it off to satisfy the FCC (true?) but can other things be done? I assume/home that the command channel is encrypted, so disclosing its existance is not compromising the bird.

As per my and other linear transponder test signal pass through but they are not too strong even if some report seems to confirm 1 watt power their EIRP is unknown assuming the command channel is on UHF but you know the word "assume" definition:)
