[AMRadio] Crystal Mic Elements for Otis

Otis left them out in the shack and I guess the heat and cold got them.
I loaned him one and he was going to get on the air Sunday morning but said
the RCVR didn't work all the time. So I need to make another trip out and
see what's wrong there. 

For those that don't know, Otis, K5SWK, uses the elements in an old RCA
housing not the D104 housing.  He can't use a dynamic of any kind as there
is way to much magnetic hum floating around his shack.  I will probably
build him a condenser circuit for the RCA housing soon while he uses my D104
and is in the mood, so to speak.  Mean while I thought it would be a good
idea to get his two D104s all up and running again.

I thought we went thought all that, a few years ago, and Otis bought a 
few (several?) Crystal Element cartridges.

Does he have any left?  Time to go visit the Ancient One, anyway...
