[NLRS] 902 cavity filters

[Paul Husby]

As the cellular world evolves, literally tons of equipment gets junked
every year, including perfectly good cavities that the companies would
rather not take the time to re-tune.  I had a bunch out at the Farm, and
when I get out there at the end of the month I'll see if I can dig some out
to bring back.  They are easily re-tuned for the ham band.  I'm sure lots
end up at Kirschbaum-Krupp and other local metal recyclers every year.
