Avionics REMF

This unit is specially designed as a low cost manual direction finder for Emergency Locator Transmitters operating on the two Intrenational distess frequencies of 121.5 and 243 Mhz.

It consists of a receiver with shoulder strap and YAGI type directionnal antennas.

Those antennas exhibit a high sensitivity in one direction (comparable to TV antennas).

When rotaded by hand, it is possible to find the direction of maximum signal.

A enhanced 30 segments "bar graph" display on the receiver is used to monitor maxima and minima of emergency signals.

Maximum is to the right while minimum is to the left. The position of the cursor on the bar vary according to the strength of the ELT signal.

The battery capacity is such that the receiver can be operated for more than 4 hours (5 to 7 hours typical).

The equipment is drift and dust proof. Thanks to the bright display, it can be used during daylight or also at night.

It can also be used for ELT location practice, using the 2 test frequencies, (distinct from the distress frequencies) which can be selected on the front panel.
