You could also try inline attenuators if the problem (now) is too much signal. I've got a selection of vintage Belling Lee ones.

One more thing, I recently had a new FM aerial erected and the rigger said that the connection to old one was non existent. So, yes, I realise that it's hard to check but poorly made or non-existent connections are often a problem, especially once a few winters have had their wicked way.

Otherwise I agree with the general sentiment on here that you're doing well to get a decent signal at 75 miles. Excellent in fact.
