Pedro,

I have a VXO with a 4MHz ceramic resonator. That signal is divided by 8. Range is 500.5 - 506kHz.
see

http://wireless.org.uk/qtx.htm

4MHz cer. resonators are available at less than 1 Euro in almost every electronic shop.

500kHz cer. resonators however could be interesting to build a sharp RX-input filter (cfr xtal ladder filter)

Hello group,

I just discovered that the European grossist for electronic parts has
500 kc ceramic resonators in their range for less than half a Euro.
this is a great building block for a tunable 500 kHz transmitter.  I
ordered some for test purposes to see how far they can e pulled.
Unfortunately they don't sell direct to customers, only to retailers.
