Hi, I also listen to a lot ATC chatter (mainly Denham and Elstree)and had exactly the same problem although it is obvious the the controller and pilot do not (most of the time anyway) to get around the problem i bought a decent radio AND aerial. The main reason for listening is that i intend take the exam sometime this year and to get back into aviation. (after learning to glide and then start my PPL at Elstree in the 70/80's and then found out i couldnt afford it, now i can afford it, ill health precludes me from taking it up again)
