'[OT] Looking for 10.245Mhz Cristal Oscilators'
avier E. Valera Garcia
I am working on an FM dual conversion FM receiver that uses a PLL
programmed via a PIC microcontroler for the channel selection. In order to
get the second IF frequency from 10.7Mhz to 455 Khz I need to have a local
oscilator that runs at 10.245Mhz.
Could somebody tell me where can i buy some of this Xtals...
Thanks in advanced,
Most cities of any reasonable size have companies that will grind you a
crystal for any frequency you like; this is probably gonna set you back
$20 or so for one crystal, though.

It's a standard crystal, so you shouldn't have many problems. In the UK
they are available from Cirkit: cirkit.co.uk.mailorder
