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
