Another item you should also take care with is your transmitter aerial, this should be protected. Now I have a good idea for this, and I have put it into practice, first buy a new set of radio (or secondhand if you can) then get a can of John Smith's Bitter, consume the beer, crack open the can and take out the widget, drill a hole in the widget and place on the end of the aerial. I have about twenty transmitters now, it's been good protecting the aerial tips. Anybody got any transmitters spare or even unprotected and needs a hand give me a call.
