That's great
I always try and see how far signals travel before they drop out. Obviously it is good to have a decent aerial in order to do this.
I don't care about the station now, but on a good car radio, Heart Peterborough (102.7) travels as far as King's Lynn - then it starts dropping out on the way towards Hunstanton/Cromer due to the large dips and hills affecting the Line Of Sight (LOS) towards the transmitter. That is out of the coverage area by a reasonable margin (outer edge of coverage is just before Kings Lynn)
Another note: Kiss FM Peterborough does exceptionally well on 107.7FM. It's only supposed to cover Peterborough itself yet goes out as far as Thrapston in a westerly direction, and Guyhirn towards the East (where the RDS kicks in and changes to 106.4FM). Towards the north west it fades out just before Colsterworth on the A1 (which is far greater than it's official coverage!)
Though all of this depends on what aerial you use. 2 of our cars have decent external aerials, so pick up radio signals well in fringe reception areas. However, the other car has a built in amplified "grid" aerial on the rear windscreen. Whoever decided this was a decent aerial needs shooting, literally, as it goes against all the rules of Radio Frequency (RF) and what is needed for a reliable signal!
Needless to say the reception in that car cuts out significantly earlier.
An amplified, very low gain aerial that isn't suited to the FM frequency's and is the wrong polarity does NOT equal an unamplified external aerial which is the correct polarity and is cut to the FM wavelengths.
