One thing we tend to forget when criticizing commercial gear is
that it must meet economic design criteria, be repeatable without
undue work and perform without unacceptable consequences.

Design engineers could do as you have Brett, but I don't think
many people could afford the finished product.  What you have is
a one of a kind receiver that meets your specifications but maybe
not other people's expectations.  Design criteria must cross many
requirements in the commercial market in order to be successful.
Thank goodness the government bought many examples of the gear we
cherish or we may not have the opportunity to possess them today.

There is not a piece of equipment out there today that meets
everyone's expectations or can not be modified to appease an
individual.  But the NC 300/303 is a good piece of gear as is the
Globe King 400/500 series of transmitters by WRL.

One must do as you have, decide what you want improved and
accomplish the task themselves.  You have done an admirable job
with your project, but I wouldn't spend that much time on it.

Hope to read your article.  By the way, if you care to contact
him, K5AM, Mark Mandelkern started a project such as yours back
in 1990.  He has a block diagram posted on QRZ when you look up
his call sign.  He also has a website which contains more
information.  You will find he is a very nice person who will
share information readily if you care to contact him.
