Thanks again to all that responded to my post yesterday for info on crystal mfr's during the war. As I slowly go througj the pile of xtals here...I'll be happy to keep a look out for any non ham band freqs you may want. So far out of 350 xtals looked at , only two 40 mtr xtals were found.
So far the highest freg found is around 8mcs. The bulk so far is around 5 -6.9 mcs and others in the 4mc range.
Also have quite a few DC 34 xtals as used on the BC669 , these all in the 4 mc range.
Let me know what you your looking for.
