Default Making your own Falconry Tracking Telemetry

I once made my own telemetry and transmitter's, the transmitter was very simple, just a single stage.
The recever was not very sensitive, and was not built from scratch, it was for listening into crystal controlled bugs, i needed to add a BFO and a directional antenna.
The transmitters cost about ú12.00 in parts and took about hour to make.

As anybody else tyred making them, and what was the results ?.

The trick is finding crystals for the UK telemetry frequencies
Another bit I had problems with is finding the aluminium tubes to build them into (this takes the place of part of the goundplane wire shown in purple above and has to be metal not plastic - the bird itself forms the rest).

I have heard of someone that made his own ferret finder transmitters and using a pocket FM radio to track them. Is this possible? Very low power of course.

Apparently you can use a radio to pick up 216

108 is half of 216 - so picks the transmitter beep up.
