Strong signal as usual from ISS again this morning during the 07.50utc UK pass. 1200bps on 145.825MHz.

But unable to get a single packet through and no stations heard, just the ISS beacon.

Tried hitting it with a full 100w but nothing.

Something up there has changed.

Has the attitude of the station been changed / boosted since 17 December?
