Re: Drake Crystal



Hi Larry:

My Drake 2880 crystals are also ICM catalog # 433492.  These were
ordered from ICM approx. two years ago.  The papers that came with the
crystals for 2304 MHz. @ 144 MHz. IF, and 2400 MHz. @ 430 MHz. IF,
show that BOTH of these crystals have an ICM catalog # of 433492.

I would have thought that the catalog # would have been different since they
are for different frequencies.  However, the catalog # must represent the
same spec data (case style, resonant capacitance, etc.), excluding the
frequency.  These crystals fit the case with no problems since they are
actually smaller than the original crystals from Drake.

73,

Woody
