It was very interesting and exciting at 13:58 utc this morning to hear A073 data coming over Fo29 .Both birds were over Quebec Canada at the time, A073 was transmitting on 145.937 , Fo29 was receiving and retransmitting it on 435.863 mhz.It only lasted a minute or so.I have only heard this one other time. jeff broughton WB8RJY
