Real ADF KR87
The KR 87 offers superb dependability in a compact, attractive TSO'd unit. It provides accurate bearing-to-station in the 200 kHz to 1799 kHz frequency range, complete with ADF, ANT and BFO tuning modes, plus audio output for station identification and monitoring AM broadcasts.
The KR 87's advanced "coherent detection" design rejects unwanted frequency noise and achieves much greater range while remaining less susceptible to engine noise, static and atmospheric interference. Its "flip-flop" frequency display allows you to switch between pre-selected standby and active frequencies with the touch of a button.
Both frequencies are stored in a non-volatile memory circuit, meaning you don't have to worry about battery power.

FLT timer Mode
rom frequency mode push FLT/SET button twice to go into this mode. This timer starts to count when you turn on the gauge, but you can control it. Clicking on SET/RST button once stops the timer. When it is stopped clicking again reset the timer and starts to count from zero. Clicking to the right of the button (area 7 above) will reset it to zero and ET begin to blink, you can use the knob to set a countdown (up to 59 minutes and 59 seconds), push SET/RST to start the countdown. After the countdown timer reaches zero, the counter will come up, whatever the mode you are in, and will begin to count upwards indefinitely while flashing for a few seconds, returning then to the mode you were before, if it was different. The Audio Alert is then sounded
