Capt Lou,as somebody who has just got this  venerable 'old bird' out of the hangar where after purchase it lay dormant,as I have been spending far too much time with the latest modern day  'heavies' and their FMC-enabled navaids,this a/c's navaids system was all a bewilderment to me until I read your oh-so-informative tuition above.Thank you very much for going to all that effort of not only a textual tutorial but like the old adage of 'a picture paints.....', I have learned something  today.

Wow! is the only word befitting what you have taken the time and trouble to do
