Hello.  I'm Dick Byrd.  This site deals with the hobby of Amateur Radio.  It's actually a very
narrowly focused part of the hobby.  Amateur Radio Operators, "Ham Operators", engage in
communication over all parts of the radio spectrum.  To increase the power output from small
transmitters, hams use amplifiers.  A company called ETO produced amplifiers for years and
operates today as "RF Concepts LLC ".   As you might imagine, their primary focus today is on their
newest product line.  My interest is in supporting the older products.  This site is dedicated to
providing information as well as service for some of these older rigs.  The information contained
here is  a reflection of experiences I've had repairing and
updating this already remarkable product line.
