    I am looking for two parallel cut HC-49 (short) crystals.

    I can be flexible with the loading, but the frequencies are 26.2144 MHz &
    22.5792 MHz. I am not looking for anything unusual except for the
    frequency.

    Do any of you have suggestions? I need about 100 pieces (US customer)


    Thanks,

    Just get them made by a crystal supplier. They won't be expensive and should
    just take a couple of weeks.

    I have emailed a few of the larger manufacturers, and most have not
    responded. Others suggest very large minimums. Can you suggest some good
    suppliers?

    You could try asking your local two way radio dealer where they get
    crystals made when they want them.

    Two places I have used in the past, both with small orders and great
    success:

    International Crystal http://www.icmfg.com/
    Jan Crystals http://www.jancrystals.com/

    If you pick some reasonable load capacitances etc. in your initial quote
    request you will speed up the purchasing process. Just saying "I don't
    care" really doesn't help.

    Only in the UK, I'm afraid.

    I use them - very good service. Don't know what they are like for 100 off,
    though.
