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.

Thanks to excellent work by Derek G3GRO the GB3LF repeater is now on the
air from Crawley on 144.9875 MHz. It's relaying the entire 136 kHz band as
an upper-sideband signal. The 136 antenna is Derek's Loran-cancelling loop
and active vertical combo.
I put my Marconi TF2008 sig. gen onto 137.5 kHz and fed a measured 100
milliwatts  RF into my inverted-L antenna. GB3LF "heard" it and relayed it
back to me; clearly visible on Spectran but only just audible.  Estimated
antenna eff. is .03% so erp was about 300 MICROwatts.  Distance is about
11
miles/17.6 kms.
Derek will be describing his repeater on Saturday at the LF, sorry, HF,
convention.

Walter G3JKV.
