Also received a min late (3:01).
Bit of a non-event really, I'd completely forgotten that a test was due.
My phone was in the next room charging and I heard it beep a few times. It sounded a bit like the Tunstall monitor modem was about to dial out. If I hadn't have been forewarned, I probably would have just thought that it was something on the TV.
btw some news reports are saying this is the first time that there has been this type of test, but Im sure we had one many years ago. Possibly more than 10 years or so.
