Couple of threads that might give you some info:
It’ll be the atmosphere what done it.
Edit: A lot of it can be due to what is called ‘the cliff’. If you have a great signal, say in the UK, you’re very far away from ‘the cliff’ and so your atmospheric conditions can change dramatically, and you don’t really get close to the cliff edge. If you’re signal is dodgy, say your outside the normal reception area, then your much closer to the cliff edge and a much smaller change in atmospheric conditions can send you over the cliff and you get nothing. That’s the cliff.
Hi all,
Trying to follow Ken Bruce upon his departure from radio 2, the OH found that he’s not on Freesat. Worse than that
The second thread, towards the end, @_Brian usefully suggested I retune our humax which worked for getting HD. The last few weeks though everything has been off - atmospherics I’m told - and now back on.
We are further south than you, but do have a large dish.
