|LOWER FREQ||HIGHER FREQ|
NOTE: SOME OF THESE WILL BE SECOND and THIRD OVERTONE CRYSTALS AS REQUIRED BY MOST RADIO EQUIPMENT SUCH AS MILITARY, E.F. Johnson, Heathkit, Knight, Hallicrafters radios etc.
CRYSTALS AT THIS VERY HIGH FREQUENCY RANGE are not all guaranteed to be perfectly accurate due to the multiplication factor on the error.
FT243 crystals have pins spaced 1/2 inch apart, and are used in MANY ham radios
the 1940s through 1970s.
Note - most of these are original FT243 crystals, some are reworked surplus units with
wire lead crystals inside as described in tube transmitter articles using them in CQ Magazine
and detailed technical analysis in Electric Radio Magazine.
NOTE: Most older crystals above 13 MHz are going to be third overtone type.

The price for one to four crystal on a given frequency is $59.00 each plus shipping.
Price for 5 to 19 crystals on the same frequency would be $46.00 each and
price on 20 to 29 crystals on the same frequency would be $39.00 each and
price for 30 or more crystals on the same frequency would be $29.00 each plus shipping.
Delivery is typically around 4 weeks after receipt of order.
SPECIAL CRYSTAL PAIRS with 455 kHz T-R offset for 160m and 75m AM etc:
(as used in BC-611 and other military radios, etc.)
These are FT243 T-R Crystal pairs for 455 kHz i.f. military radios such as BC-611 etc.
(For some pf these, I only have one pair left)
1885 - 2340 kHz
1945 - 2400 kHz
1985 - 2440 kHz
3685 - 4140 kHz
3735 - 4190 kHz

Available for $16.00 per crystal.
Some of the FT243 crystals above are remanufactured crystals using original
WW2 era FT243 holders with a newly manufactured, HC49 or HC49US hermetically-sealed crystal
mounted inside. Like all crystals, these should not be used with a grid current
of greater than about 60 mA. They have been used successfully in many typical rigs
like the Heath DX40, HW16, DX100, Ameco AC-1, Drake 2NT, Hallicrafters HT-40, BC610,
Globe King, Homebrew MOPA rigs etc.
FT243 CRYSTAL Sockets - I currently have THREE types available:
Original style plastic crystal sockets.
Original National ceramic sockets
A few Original James Millen NOS ceramic sockets, while they last.
Shipping costs will be added to all prices!
