[amsat-bb] Digital QRM on FO-29

During two passes of FO-29 - at around 0120Z last night and around 1430Z 
this morning, I've heard some QRM that sounds like a digital signal. I 
confirmed that others heard it too and it wasn't local QRM, so it's 
obviously being relayed by the satellite. Downlink is around 435.860 MHz 
(I heard it around 435.865 last night as the satellite was approaching 
and around 435.855 MHz this morning as the satellite was moving away), 
so the signal is likely being transmitted around 145.940 MHz.

Has anybody else heard it? Any ideas on what the source might be?
