[Milsurplus] Xtals, we've got xtals...

[Unserviceable but Repairable]

A handful in FT243 pkgs marked channel 20, or channel 32, or....

If fundamental freq. multiplied by 3 & 2880 kc added, it comes out 22 mcs, 
23.2 mcs, 24.6mcs (7240 fundamental), etc.   This is like markings on 
FT 171s for BC-604s.  So I'm gessing these are BC-620 xtals.

2880 kc FM IF, yet.

Then there's some marked channel 981 / 98.1 mcs (8591.7 fundamental).  
If 12x multiplier & 5 mcs subtracted you've got the freq.  Wonder what 
kinda FM set we had @ 98.1 mcs?

Mayube not FM awreddy.

Be gentle - I'm sure half of you guys live day in & day out with this
