Apologies if I've posted in the wrong place .
I have been using one of those cheap T-shaped wire aerial for my fm tuners for the past 2 years which was fine with my Yamaha and Kenwood tuners and then I went back to the old Quad fm 4 a few weeks ago although I was only getting 4 bars it was listenable, then yesterday I decided I'd try the same aerial outside ( pinned to the fence lol ) hey presto 7 bars !!! Trouble is all stations are fine except the one I listen to which is radio 2 , there is a constant humming sound .
Now I know the aerial is shite and a crazy idea, I will install a proper fm aerial once I know the benefit outweighs the cost .
So why the humming sound?
