This leads on from this thread.
If you go to the wavefinder site, you'll find links to loads of dissatisfied customers and suggested solutions to some of the problems.
My two are plugged in to chimney mounted DAB aerials, directly pointing to the nearest transmitter by map reference: signal strength is A1, it goes fine for weeks, but then it loops and stutters. The other problem is that it records the first item on the scheduler and then cuts out, regularly, and always if it has to switch programme - I've moved on!

I found this excellent terrestial digital gizmo which does the job much better. After the usual teething probs. that a technological dunce always has, it seems to be 100% reliable and the 192kbps sounds much fuller and crisper.

My only problem is that the 3alpha we got at Amersfoort doesn't want to know MP2's, so I'm having to convert them to 3's with Audiotools
