then its ok, you will probably find they just aint as popular as they used to be, if you see a group of 2 or three wagons running in convoy they asare normally on one of the channels chattin away, you just need to find em. i see you are in east lothian, a lot of the scottish timber hauliers use the mid 30 channels
if the power markers only go up to 4 there is a problem, it should go to 30+ when you key up. i still run a 40 channel fm 27 mhz with no problems at all. on the front there is a circle with 27 AND 81 in it, this is what they call the old 40 as opposed to the new 40.
