[Premium-Rx] Harris R-2368/URR receiver information sources.

Gentlemen,

Whenever I acquire a new (used) receiver, I try to learn as much as I can
about it.
Regrettably, it isn't always easy to find all the relevant information,
no matter how hard you try. 
It seems to me that most owner's and service manuals are just barely
sufficient to satisfy the need for operating the radio and technical
advice, and often are written in a rather ambiguous manner.
The Internet has certainly facilitated the search but not necessarily the
results.
When it comes to in-depth information about accessories, modifications,
upgrades and sources for replacement parts for a specific model, the
search often becomes an excersize in frustration and many times in
futility.

I have been unable to find any information on the following topics
concerning my "new" receiver (a Harris R-2368/URR made in 1990):

 1- A small metal tag on my radio's left side from the front reads:
"CONFIG NO. 10295-1010"
 Any ideas where I may find a listing of the various configuration
options, and how they relate to these numbers?
 
 2- There is an 8-pos dip-switch S2 on the CPU board called "Bandwidth
Selection Switches". 
 What does each switch represent? - the explanations in the manual are
rather ambiguous and vague.

 Anyone have the details (circuit description, schematic diagrams, etc)
of the optional Noise Blanker (A20)?
 The same goes for the optional Syllabic Squelch.

Can anybody come up with some or all of the answers?

Thanks and 73's,

Pete [KA5FUN]
