40 Meter Crystals for Ham Radio (several frequencies available)

Description

You are bidding on used 40 Meter Amateur Band Crystals. Most of these are packaged in FT-243 holders as shown in the photos, but some are in Bliley AX-2 holders. The AX-2 crystals have the same pin spacing and pin diameter as the FT-243 units, but the cases are slightly wider and shorter. Please see the photos for more details. AX-2 crystals are identified in the list with an (a) following the frequency. The 'buy it now' price is for ONE (1) crystal. Several frequencies are available as shown, but in general, most of these are "one of a kind" crystals, so unless larger quantities are indicated, once sold out, that frequency is gone. All crystals have been tested for activity using a crystal tester featured in "73 Magazine" (January, 1992) and checked with a frequency counter (see photos). All show activity and frequency within +/- 2.5KHz(max) of the stamped or labeled value on the counter. The actual frequency may vary in the application circuit due to circuit parameters, so please keep this in mind when choosing a crystal. Some crystals may be also have additional markings with higher frequencies if they were used in "multiplier" circuits for the 15 or 10 meter bands. Shipped via USPS First Class. Shipping costs will be the same for up to 4 crystals. If you are interested in purchasing more than 4 crystals in one order, please contact me for combined shipping costs.
