NDB/DME Radio Direction Finder + Emitter Set

Need to navigate to a radio beacon? Want to easily follow your friend? Need to find a boat you left behind? If you've answered "yes" to any of those questions - this microcontroller may be for you. It utilizes 4 antennas arranged in a square for a bunch of cool radio things.

- Requires no GPS receivers
- Allows to find other vehicles without specialist datalinks and equipment
- Requirements for target vehicle are minimal (A single radio antenna that can transmit, it is not required for the target vehicle to have this microcontroller)
- You can find someone using a handheld radio at the distance of up to 20km (with the receiver made of huge antennas)
- Allows to create custom named NDB beacons which will provide distance measurement for other vehicles

- Gets bearing information to ANY active radio emitter
- Gets range information from dedicated NDB beacons
- Gets 3 letter emitter name from dedicated NDB beacons
- Allows to create a dedicated NDB beacon with a simple press
- Allows to create a secure TACAN radio station when used with the AN/SRQ-420 radio
- 8 colour schemes
- In the near future: Distance measuring to any radio emitter
- In the near future: Coupled autopilot which will home onto radio emitters


Antennae arrangement:
The microcontroller needs 4 identical antennas arranged in a square with 3 blocks of space between the antennas. The antennas need to be connected to the microcontroller in such a way to align with the vessel as described on the microcontroller.

It is highly advised to have the antennas powered by a charger to keep them in good calibration.

Microcontroller:
You need to select the right antenna size that you used to create the array, additionally you can choose the 3 letter name of the radio emitter in XMIT mode in the microcontroller properties and the colour scheme.
