AM/MW, but FM/UKW?
Skeeter Abell-Smith
labels were AM/MW and FM/UKW. MW is obvious, but I have never seen UKW before.
Is this an old or new designation? Did someone just make it up? What does
UKW stand for? United Kindom Wave? Ultra Kilocycle Wave?!? :-)
Curious,

If it is a German radio, I suspect the "MW" is the
German Mittel Welle, or Medium Wave.

"UKW" is the German abbreviation for VHF (where FM resides):
UltraKurtzWellen (I have trouble spelling in English, so I
probably murdered that!).

No, you spelled it almost fine, It's "UltraKurzWellen".
Kurz means small. And ultra and wellen are obvious. It directly
translates to Ultra Small Waves. What about USW instead of VHF????

The radio is German.
LW = Langeswelle = Long Wave
MW = Mittelwelle = Medium Wave
KW = Kurzwelle = Short Wave
UKW = Ultra Kurzwelle = Very Short Wave = VHF (usually FM, but only 88-~100mhz)
Interestingly enough, now that you have made me thing about it, I don't
remember ever seeing anything equivalent to our UHF abbreviation.
Now where did I leave that German Physics book?? :-)

For those who missed it: UKW stands for "UltraKurzWellen". It's the
German equivalent of VHF.
On a side note: Why would a radio sold for use in Canada have German
markings? A friend of mine had a clock radio from Germany (or was
it Austria) and it gained like crazy because it was expecting to
reference from 50 Hz power.

The radio with FM/UKW is probably German-made, or
was also intended to be marketed in Germany.
As for your friend's clock radio, if it's digital,
it probably has a switch for 50/60 Hz inside somewhere,
and if the clock is analog/mechanical, would require
some sort of gear change. I have an Akai reel-to-reel
tape recorder (purchased in Germany) that has a
50/60 Hz adapter kit.

As you said, obviously MW means Medium Wave which is what the Brits call the
AM broadcast band.
FM is known by those Brits as VeryHigh Frequency (commonly VHF)despite the
nostalgic hankering for wavelength designations.
Meanwhile the Germans who produced Herr Hertz, conceiverof frequency,prefer
to think of FM as ultra-short-wave, in german Ultra-Kurz-Welle, hence UKW.
No wonder psychiatrists are often pictured as germans.

It's the German abbreviation. KW = Kurzwelle (short wave); UKW = Ultra
(I think) Kurzwelle = ultra short wave.
Don't confuse it with the German abbreviation LKW = Lastkraftwagen
= cargo truck (American) or lorry (British) :-)
Now ... since the Germans say Ultra Short Wave where we would say
"Very High Frequency," what is the German equivalent of what we would
call "Ultra High Frequency"?

When engraved on equipment its often seen in the form VHF/UHF which implies
they are thinking in english, however UHF could also be Ultra-Hoch-Frequenz so
there's no problem there.
To extend the thread even further though, its common in documentation to see
the frequency range 470-860 MHz called Band 4/5 or the by clasically minded as
Band IV/V. This fits in with the band numbers used (at least here in europe)
for broadcasting, Lo-VHF = band 1, FM-VHF = band 2, Hi-VHF = band 3 and
UHF is broken in two parts bands 4 and 5.
Back in Olde Englandeof course TV antennas have their own designation by
channel groups (about 10 channels of 8Mhz wide) , groups A,B C,D and some odd
overlapping ones.
Perhaps someone else could expand on the names for the cable tv bands, I'm
getting keyboard cramp.

It was real fun to follow this discussion, sitting in Germany...
There definately is no need for further explanations, certainly,
as to what UKW and MW mean (although I've got no idea either,
why this is found on a radio in Canada), it has been all said
very well. But one thing confuses me still: there was no comment
why actually the discription of an exactly defined frequency range
like "Medium Wave" or "Short Wave" is called "AM". We all know that
this means Amplitude Modulation...BECAUSE that modulation kind is
used for regular broadcasting on these bands, as FM, Frequency Modulation
is used on the UKW - sorry VHF range. I mean, AM is also used on VHF
frequencies, like the Air Band, isn't it. Would you call that "AM on FM" ?
Probably not. So this AM and FM on radios irritates me all the time,
to say
Long Wave
Medium Wave
Shortwave
VHF
UHF
EHF
makes a lot more sense (in German letters AND in English), doesn't it.
BTW: As many of you said, UKW is VHF, but UHF is UHF in German...
confused?
