Surround sound

I replaced the old battries in 2 old transistor radios and decided to have a little surround sound in my study. So I put one in front of me and the other on the shelf behind. Even though it pales in comparison with those sound systems, hey, better than nothing right? But the catch is that one of the sets has a hopping frequency which means that it does not remain at only one particular station but it changes station incessantly. So after a while I have to keep pressing the serach button in order to get back my favourite station which I have grown up with for years. Class 95.
