[Keith Rowland]

I know I promised one group per day until finished, but have some extra
time today, so am posting Part 2.  There are a total of equiment, some
with several mod articles each, so maybe I can get 'em all done this
weekend, despite attending the Lawrenceville Hamfest tomorrow and
Sunday.
