Dear LF Group,

HF Automatic Antenna Tuners

Nothing to do with LF I know - but several members of the LF group 
are clearly involved in RF engineering, so I thought I would ask. 
Otherwise, please ignore this message, and my apologies for 
cluttering up your computer!

I am currently doing some research into automatic antenna tuners - 
the first need I have is to find out about the current state of the art 
of automatic ATU design - particularly matching network design, RF 
switching & tuning devices, and tuning algorithms. I have not been 
able to uncover much on the subject from the technical journals & 
magazines - the articles I have are over 10 years old. Relatively 
few people seem to be interested in actual radio hardware at the 
moment, all the trade press seems to be full of network routers and 
message handling protocols. Therefore, I would be extremely 
grateful for any current information, or references where I might 
find such.

Cheers, Jim Moritz
