I'm asking this question here primarily because you chaps might have a better understanding of radio transmission and it's idiosyncracies. If this is the wrong forum please move it on to where it belongs
I was listening to my pocket radio today, to LBC 97.3FM to be precise and was painting some decking in the sun. All well and good, however, I noticed that when I moved in a particular direction in a particular place I was able to listen to the approach frequency at LHR! The radio goes up to 107FM and has an antennae that is boosted by the earphone cord and perhaps the user. I was surmising that the cord was acting as a tuner that was able to jump the range of the radio. Assuming that the LHR frequency is 118.0 to 125.0 somewhere, that's quite a jump from 97.3.....
Anyone care to give an in-depth explanation, apart from that I might be able to start a personal radio station
Thanks
