chrisN thanks for the frequencies. I asked as I thought that it might be useful, when in the vicinity of somewhere like Biscester on a sunny Saturday, to listen out to 130.4 or 130.1 to give myself a clue regarding the position of invisible gliders.
Undisciplined use of radio is by no means limited to glider pilots unfortunately
