Thanks to all those who posted initial comments on the reflector re MB7LF.
It will actually be Stewart G3YSX who will be presenting the short paper at
Windsor on Saturday 13th October with some recordings etc.and who was
heavily involved in submitting the application and assembling the hardware.
I shall be attending on Friday afternoon with Lech G3KAU to install a 2m
antenna for a demonstration on Saturday (hopefully  !!) and of course again
on Saturday.

    - Looking forward to meeting old friends in the LF group for an
"eyeball" and natter again.

            Vy 73  de  Derek Atter G3GRO
