This is a follow-up to a message I sent out late last night. As I duplicated the entries below with the -D as needed for the Icom radios to place them into Digital modes from SatPC32.
We were taking yesterday about the potential risk of contention with the normal ssb users of the sats, and in an effort to try to error on caution, a few of us put together a list that has a transponder bandwidth greater than the 20khz. Some have 30, 50, and even 100 wide. Taking the bottom 5khz, it should provide plenty of elbow room there. Perhaps another 5khz above these could be used for other digital modes like FreeDV, Vara, and narrow and fast digital modes off all types. We went through several passes last night on FT4 and the seemed to work, but I would like more of your testing feedback to see if this gives us the results we need.
