>>> A packet with a digipeating path will not be spoken

Your updates are very helpful as we learn about the capabilities of this
new satellite - thanks Bob!

Regarding the text-to-voice, are you saying that we should not transmit
messages in that format to the normal 'ARISS' path?

If not, then what path should be used for text-to-voice messages?

Thanks!

-Scott,  K4KDR
