Cool. Now if I could just read Russian.

You should try hard, we read English and do not make a problem out of it... Good luck!

Quote: RMorg also provides a tool to enter cyrillic letters and somewhere has hints for transliteration I went there, but wasn't smart enough to know to use the "backward N" for the "U", hence no hits. Thanks for the link. At least I was smart enough to realize the dial is calibrated in wavelength rather than frequency.

Quote: Портативный радиоприёмник "Невский-402" с I-кв 1987 года выпускал Ленинградский приборостроительный завод "Равенство". Малогабаритный супергетеродинный радиоприёмник ''Невский-402'' создан на основе серийного радиоприёмника ''Невский-401''. Из особенностей приёмника - подсветка шкалы, являющейся и фонариком. Rough translation: The portable radio Nevskiy 402 was introduced in the first quarter of 1987 by Ravenstvo (Equality), an instrument manufacturer in Leningrad (Saint Petersburg). This compact superheterodyne radio was based on the model 401. Notable features are an illuminated dial and a flashlight. 2 Bands: MW - 525 to 1,607 kHz; SW - 5.95 to 12.1 MHz. Below is a schematic diagram from Radio No. 11, 1991. It looks like the heart of this radio is an IC (K174XA2). It has an RF FET and four transistors which form an audio power amplifier.

Guess what? Inside the lining of the original box I found a schematic sheet and instruction booklet. What are the odds? I put in a 9v battery and it plays too. I was a little disappointed it was in English though. The thumb knob (#3) just spins around, must be slipping on the shaft. I know how to turn on the backlight, but can't figure out the flashlight. It looks like there is a slide switch (#11), but it doesn't move. I've scanned the documentation if anybody wants it. It's a 3.5MB PDF file.

I thought I could answer my own question about this radio by doing an on-line translation. I got the translation, but it didn't tell me anything.
Knob three in the diagram translates to "knob accurate adjustment". So, adjustment of what? Is it a tone control, or maybe a fine tuning thing? The knob turns all the way around as if the knob is slipping on the shaft.
Also, is the switch for the flashlight a slide switch, or a push button?

Off-topic..... Americans have never been big on learning other languages. By contrast, most educated Europeans--and Russians--are quite fluent in English, and maybe also French and/or German.
i remember listening to a talk by a Russian scientist. At least twice he corrected the interpreter--in perfect English.

2vlad, thank you for the photo and labels. Since the fine tuning knob seems to have no effect I'm thinking it is slipping on the shaft. The flashlight switch on mine seems to be stuck. At least now I know which way it's supposed to go.
I don't see American's lack of foreign language skills as an educational or intellectual shortcoming, but rather a lack of necessity. The multilingual Europeans I've met mostly have a need for it, education, tourism, international business, aviation, etc.
