FOR SALE:  Group of 40 FT241 Crystals in new condition.

Quantity of 40 old FT241 crystals. These are the LF range crystals as
used in the military BC620 and BC733 radios. Excellent condition.
During WWII these quartz crystals were manufactured for use in
military vehicle radios. 

These crystals are marked for frequencies in the 20 - 40 mhz range,
but the fundamental frequencies are much lower.
Some of the crystals fall in the 455 khz range, and were used by
homebrew radio builders in the 1950's onward to make crystal
filters, especially for SSB exciters (see early 50's ARRL handbooks).

These are LF crystals in the 300 - 500 kHz range. Marked with channels
such as 14, 19, 60, 68, 317, 320 (sorry no specific choices offered) but
for example, Channel 68 = 496.3 kHz.

Will sell the box of crystals for $15.00 plus shipping.
