Hi, does anyone know where I can get a schematic for a ferret locating
collar transmitter. the commercial ones are usually fitted inside a TV coax
plug and runs on button cells. O/P frequency is in the medium wave band.

Thanks in anticipation.

Hi, Thanks for info but this one is for vhf and the one I require is for LF.
around 500Kcs or so and hopefully small enough to fit inside a tv coax plug. Thanks for trying.

 

Well there is this circuit ,

they dont get much smaller unless that is
one uses surface mount devices.
