An extensive review also appears in August QST. Nice box, but at $499 
a lot of money even at the current exchange rates unless you have 
another application than the MF bands.

Rather less convenient but far cheaper is Peter's 3M bridge. I 
adapted this and improved its accuracy and found it a perfectly 
adequate method of matching my antenna. I have a detailed description 
on my website 500kHz pages.

But it is probably academic now. With yet another station giving up 
the band last night because of a drop in activity and other reasons I 
feel things have past their peak. (G3XAQ, G3XIZ, G3VTT and possibly 
others have now gone QRT). Unless new stations come on the band for 
proper QSOs I shall do likewise and not waste my time (which is a 
pity as I am giving a talk about the band at my local club on 
Wednesday...).
