This 80 metre fox-or transmitter is a very small low power transmitter which mounts inside a plastic conduit. Its primary use is small foxhunts and fox-or-ing (orienteering style) foxhunt events.

The PCB measures just 40x12mm and runs off a pair of AA batteries. The transmitter operates on the fixed frequency of 3.58MHz and has an output of approximately 6dBm (4mW).

A short antenna about 40cm long gives the transmitter a range of about 100 metres. A longer antenna will give greater range.

Completed boards and components have been acquired and boards will be populated shortly. Mechanical details will be completed towards the end of this year.

The transmitter will be offered in two formats:
1) As built and tested boards only.
2) As a completed ready-to-go transmitter including plastic conduit and battery hardware. (but not including batteries).

For fox-or-ing use a typical course will use between 5 and 10 transmitters.
