I am trying to find a 10.400mhz crystal to replace the one in a Uniden
scanner I have. I have tried all the usual places such as Digi-key,
Mouser, etc. I don`t want to order from some place such as International
crystal because they would probably want a fortune for it in small
quantities. Any help would be greatly appreciated! Rob

I've had good luck ordering custom stuff from Cal Crystal Lab / Comclok -
they seem to be quite good about providing onesies and twosies to
individuals.

Their web site is www.calcrystal.com - they don't seem to have a
10.400 in stock at the moment but I'd encourage you to give them a
call and see what they can come up with.

Well, they are the one place you will get EXACTLY what you need. But they
will be slow, and they wiill be expensive, although probably not "a
fortune". For a scanner, it probably only needs to be in the neighborhood.
Have you thought of taking an old FT-243 and grinding it? Probably your
scanner has an HC-49 or something so you would have to cobble something
together, but if you can find something in the neighborhood you should be
able to move it a bit.

I'm not sure how much a "fortune" is to you :) but JAN Crystals would
probably run you $15-20 shipped.

Being a Uniden/scanner part maybe there would be better luck at just
finding an old junker scanner?

If this is a newer multiple conversion scanner and if this is the 2nd LO
crystal, you will want it to be on frequency.......otherwise, your receiver
will be off frequency and you will have unsymmetrical adjacent channel
selectivity. You want your high and low frequency passbands to be centered.
10.400MHz is an uncommon frequency to find in the "junk box" so you will
probably need to order it from one of the crystal manufacturers. If you
don't have an internal trimmer to warp the crystal on frequency (your
scanner hopefully does), you will also need to know the load capacitance for
the crystal when you order it.
