My NCC-1 was purchased from DXE back in 2008-2009 and has never been used.  
Apart from changes to the manual, are there any evolutionary hardware changes 
or modifications?

G’day

For those looking for insight into how the NCC-1 noise canceller
works, I’d suggest looking at the following two web pages:

1. http://www.eham.net/ehamforum/smf/index.php?topic=75951.0

This is a thread on noise cancelling started by Martin G8JNJ and
finishes with a brief exchange of posts between Martin and Tom W8JI
(who according to the second of Tom’s posts here, is the person who
designed the NCC-1).

2. With this in mind, then have a look at Tom’s web page at
http://www.w8ji.com/mfj-1025_1026.htm.

If you read this on the basis that Tom designed the NCC-1 and that he
talks about the homebrewed noise canceller design he uses on his web
page, that may give you a good insight into the design of the best
noise canceller on the market. ;-)

While there may not be a schematic available, there is some very
interesting information available about the thinking behind the NCC-1
design.

I should add that Tom's web page is a gold mine for those who want to
understand about how to do successful noise cancelling.
