They don't come up for auction very often, but a really handy one I was 
fortunate enough to land a few years ago is the SECO Model 500 
"CRYSTalignMETER".?? It was obviously made for the CB crowd back when the 
rigs were all "plug-in" crystal-controlled and the operators were still 
"sorta" trying to be legal (remember CB callsigns - i.e. KPH4939).?? 
Anyway, I've found it to be a handy solid-state checker for unknown 
crystals.?? It has sockets for HC-17 (which also fits FT-243 holders) and 
HC-6 crystals.?? It probably wouldn't be that difficult to add a socket 
for the HC-25 "scanner" type crystals.

It does have a meter, so that's a plus over the "idiot light" designs 
using an LED to show crystal activity.

FWIW ...
