[ARC5] Odd Freq FT-243 you looking for

[hwhall@aol.com]

 I have some extra 80M crystals in HC-6 can sizes but mostly wire leads vs pins.

 I have purposely bought as many FT-243  crystals as I could in any frequency below the 40 meter band, then I etch them to a chosen frequency with Whink Rust Remover. It is slow, but works well. I am slowly accumulating 40 meter crystals beginning at 7000 kHz every 5 kHz to the top of the band.
80 meter crystals are hard to find and 160 meter rocks are just plain scarce to non-existent. 60 meter crystals might be a bit easier.
One can also get artist's glass etcher at hobby stores. Both contain hydro-flouric acid, which is dangerous stuff even at low strength.

 Are the frequencies on the crystals channel or crystal frequency?
 If channel frequency and receive crystal, the crystal frequency could be a by offset by an if frequency and a multiple of the crystal frequency.

 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.
