I am in a dip at BA3 5XU. top arial (But fairly old)
Since 27th March BBC from arial has been a problem.
Humax box. BBCA channels are found on (698.0MHz) but is poor and freezes a lot. Signal strength is ~75% but is is erratic. Average 50% but varying 40-80%

ITV etc has good reception. Signal strength ~82% and quality 100%

Also appear to have problem with SDN group. (these channels not found in auto search)
Channel strength and quality (manual tune) is same as BBCA.

Have tried removing any old with no improvement.

Any ideas please? How can I tell if it's arial related?
