Hello LF/MF group,

I though this may be of interest to those what would like to build the
simplest transmitter possible for MF.

I found these cheap crystals on eBay:

http://www.ebay.com.au/itm/2-PCS-15200-KHz-HC-49-U-X-TAL-Bargain-Pack-HC49U-/320828846717?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4ab2e3b27d

They are 15200 kHz which can be conveniently used with a 74HC4060 to
make an oscillator, then connect to the divide_by_32 line for a nice,
stable 475 kHz signal. You can then drive a class-E FET PA for any
kind of power you like.
