Does anyone know what IF frequencies are normally used on 70s - 80s era
Soviet transistor portables? I have these three:

Alpinist 418
Sokol 308
Orbita 2

I'm sure I could sniff 'em out with a signal generator, but I'd like to have
the factory spec.

I've got a 1980's Soviet-era desktop AM-FM radio----will check mine out.

For many years 465 KHz was standard in single
conversion consumer receivers (tubes and solid state).
Copied from other west european manufacturers...

That makes sense. I've got a Grundig with an IF of 460 kHz. I figured the
difference had something to do with the European 9 kHz MW channel spacing
and the possibility of interference from IF harmonics. Don't know for sure,
though. 465 used to be common in the US before WW2. I doubt there's much
practical difference.

Frank do you know of a way to use the radio here in the US? It runs on
220v and has the Soviet-style FM frequencies (54-88mhz) in the FM band
that goes up to 108. It's got the standard Euro pin-type plugs. My
converters I use when I travel overseas convert 120 to 220.

Are there such things as "reverse converters?"

If you want one, I can get a cute little convertor (autotransformer) here
that will supply about 100 watts, and can be used either direction (though
most of these small ones have to use adaptors). I can get a 1KVA one that
has thumb nuts on it that you can connect either set for input or output.
These are pretty cheap here.. on the order of $25 or so for the 1KVA model..
plus USPS shipping.

Yes, they're called "step-up transformers". I've never needed one, and I
have no idea who the best prices and vendors are, but I entered "european us
step up transformer" in the Google search box and got:

This was the link at the top of the list:

http://www.voltage-converter-transfo...ansformer.html

Again, I don't know if that's a good deal or not, but they seem to be
commonly available. They may be locally available, probably in big cities
with a large immigrant population.

Any true transformer which transforms 220V to 120 will also be able to
transform 120V to 220 when hooked up in it's reverse direction. However,
many of the inverters and "transformers" use lighter, less expensive
electronics to do the conversion, and won't work in the reverse direction.
It looks like the transformer in the above linked page will do either
step-up or step-down conversion. If you have some transformers around, it
may be worth checking if they will also do the step-up conversion.

If your clock radio has a mechanical clock, the clock will run fast on US 60
cycle per second power, rather than the European 50 cps power. That
shouldn't do any damage.

Liypn, he who sells the Degen 1102's to everybody in this newsgroup via
ebay, sells the 220-120 converters that he includes with the 1102's
separately for $8 or so I believe. I have a 220-120 converter that I
bought from a local electronics store in order to run a Euro clock radio
I got on Ebay Spain because I liked its unique styling. The converter I
have was made in China but sold under the name "Great Value" or "Good
Value" or something similar. I didn't realize that Euro electronics run
on 50hz instead of 60hz, so my new "radio despertador" ran VERY fast,
with a 50 second minute instead of a 60 second minute. Oh well, I've
got it tucked away in its original box somewhere.

The converter you got with your Degen may not be able to handle something that draws more than a few watts.

On your 50hz clock radio, you might be able to get a premium price for it by selling it to someone who bills by the hour.
