BAD,

I saw that unit in my life; it was considered an upscaled portable. I never owned it.

I could post that question on the Ukrainian forum with Petro, see if someone replies.

My feeling is, the stereo button is pressed when you want the output going to an amp; the unit itself is likely incapable of reproducing stereo. Also the headphone output will be reproducing stereo.

The four buttons on top, left to right:

АПЧ - Авто Подстройка Частотьi (Auto Frequency Control), MП - местньй прием (Local Reception), УП - Узкая Полоса (Narrow Band), ШП - ШумоПодавитель (Noise Reducer).
Bottom knobs you know: Volume, Tone Ctl, Stereo.


Wires on the Converter:

Светльiй - Light-colored, Antenna Input (to your antenna).
Темньiй - dark colored, Antenna Output (to the radio's antenna input).
Провода Крепления (top of the picture, saying БК on one of them) - power battery minus
Красньiй - red, power battery plus.

if using power supply for the battery, it should be isolated.
