Couple of clear sunny days up here in the North West, UK and the Jughans Mega 1000 has sync'ed up two nights consecutively - well chuffed. :P
Looks like the weather is the culprit and more so the further away you are. Cannot think of any other factor except if the transmitter was on reduced power over Christmas - but doubt that as it fit's in with Collectors findings (above).
This was not a forced manual sync, just LEFT it on the window sill this time!
