Andy, the MET heard was 14 minutes after a voice message and a SSTV tx.
First 5-6 minutes in the pass: no signals.

Oggetto: [amsat-bb] Arissat-1 silent over UK: Explanation
As reported over the weekend, Arissat-1 is no longer audible in the UK,
because she does not switch on until after about 14 minutes from entering
I believe the sequence is:
enter sunlight: MET starts: timer activated
14 minute wait before tx - other systems live
Tx on with data at a MET of 14 minutes
We in the UK now have to wait unril the orbit continues to precess to the
late evening (about 10 days' time)
