Yes Reg FGQ died last summer. In case his original site dies there 
are apparently already a few image copies of it on the internet.

You (and others) may want to look at my website where I have quite a 
lot about matching my own vertical and adapting the G3LDO 3M bridge 
to give good results on 500kHz. Still a work in progress... and 
matching my tiddly vertical is an awful lot different from matching 
Tom's quarter wave....

You are quite a signal here Tom! I have just added a new recording of 
your beacon this morning at 
http://my.opera.com/davews/blog/2007/06/05/500khz-recordings which 
will give you an idea... (by the way, it is intended you download 
these recordings rather than trying to play them direct on line).
