Future Pundit thanks for the freq's, I trundle past Bicester quite often and am always aware that there are slim fast things there. Oh yes, there's gliders there as well

It'll be nice to tune into 129.975 to listen to the unpowered bods.
chrisN while appreciating your point regarding:
a) cluttering up an already busy frequency
b) a lot of glider pilots turn the radio off
I still think it's worth listening out as well as having the Mark One Eyeballs searching the sky.
PS If you see a cream coloured Auster waggling it's wings frantically (well as frantically as you can with Auster ailerons) it means I've seen you not that the wings are going to drop off!
