Subject: [Amps] Sad State of the Hobby

A friend of mine has been getting himself interested in building a super Full legal limit solid state amplifier.  What is catching his attention are the relatively low cost high power FETs available out there.  I know he is looking at the modules available from some Russian on eBay.  He has started to get me interested but I am no design engineer.  This evening I started researching this topic on the internet and was amazed at the lack of good info on the subject.  Stuff there is 10 to 15 years old.  I did a search at the ARRL web site and they have a 1000 watt amp article in their QEX magazine but that was way back around 2002 or so. OLD TECHNOLOGY! What is this?  Nothing for 15 years?  I knew the ARRL was falling behind in their technical articles but 15 years with no amp construction article?  Man, this is truly sad!  I suspect there are no decent articles on building one anywhere.  This hobby has truly sunk to a new low.  Guys can't even build their own dipoles anymore.  I admit I am no design engineer but I can still build stuff.  Even on this reflector I can't remember any talk about modern day amps and how to build one using the newly offered high powered FETs.
Lee, w0vt
