Hulmey, have you managed to sort this?
I have exactly the same issue with interference.
I thought it may be something to do with the Aerial, so I planned to replace it earlier until the whole thing came out of the base!
Not sure what to do now other than change the whole base which sounds like it could be a good idea anyway?
Does anyone have any suggestions on where I may be able to buy a complete new base and aerial and how to fit?
I have not been on the forum for a long time so not done many searches on this so apologies if it has already been covered.
Cheers
Tom
