Z zanor New Member Mar 31, 2006 #1 This may be a dumb question but I have some XT crystal that I'm not sure how to read theire frequency. Theese are the labels: 8.867238 (is it kHz? MHz?) 4000.000 (4000MHz? 4MHz?) 6.000 (6MHz? 6KHz?) 4000,000kHz (That's the same as 4MHz right?)

Please explain.. Click to expand... The PAL colour sub carrier is 4.43361875MHz, many modern decoders use a crystal of double that frequency - so it's a colour decoder crystal from a 'modern' PAL TV.
