Since Saturday 9th December there has been a weak signal on BBC
national services on DAB, where I live near the centre of Leicester.
Local services have not been affected. Also, they went off altogether
for a bit on Saturday.

I've tried calling BBC Reception Advice, but they say they don't know
of any transmitter problems.

According to the display on my set, it seems to be the 'Digital 1'
multiplex that is affected.

Anybody know what's happening?
