GW9100 got five rings for 5 atomic different bands. I always got the US sync until last week in London and Cologne.
Here are the sync shots for the signals from UK and Germany towers. Need to go to Japan to get the remaining two sync shots...
(a) London Tower Bridge (Dec11 2011) - "Sync at 6 o'clock Ring"
(b) Coming Home at Cologne Airport (Dec14 2011) - "Sync at 4 o'clock Ring"
(c) Back at Home at U of Michigan Football Stadium (Dec15 2011) - "Sync at 1 o'clock Ring"
