Even a double balanced mixer cannot completely remove the two
frequencies we start with, only lower their level a lot.

In this case there is no need for that level of detail. The OP just
wanted a simple way to tune in the air band on a common FM radio.

If he had asked for a very high quality communications receiver class
solution there would have been a need to talk about double balanced
mixers.

The freqs from 109 MHz up to the 144 MHz ham band are all used by
aircraft for both navigation and communication. In the U.S.
unauthorized transmitting on these freqs is a real big NO-NO, and will
cause the FCC to jump on you like flies on dog doo-doo. If you're going
to screw around with low power RF, do it in the low part of the FM BC
band, 88 to 92 MHx, or the 82 to 88 MHZ TV channel 6 if it's not used in
your area. If TV Ch 6 is used, then Ch 5 should be free. And there is
also the band for radio control of toys somewhere in the 72 to 76 MHz
band.

Unless you're someplace like Escondido. LA has 2, 4, 5, 7, 9, 11, and 13,
and San Diego has 6 and 8 that I know of, and probably 10 and 12.

Good Luck!

Don't forget that 75MHz is used for marker beacons on aircraft Instrument
Landing Systems.

Playing around between 108 and 136MHz is a sure way to get into serious
trouble - probably even make the news media when you get arrested.

Common use or not, the use of "you're" for "your" is *ABSOLUTELY,

our educational system is here in the US, but it's still *WRONG*.

The native english speaking world has had a strong influence for many
years and still does. But the number of non-english people who use
english is steadily rising, and there are 5.5 billion more people to come.

I have seen how the situation has evolved over the last decade.
In the beginning I was very alone among loads of americans and a few
brits. Today the non-native english speaking participation in many
newsgroups is around 25 percent, and it is growing.

I predict, based on the current tendency, that the situation will be
50/50 within 2 years, and after that the native english-speaking will be
in a quickly shrinking minority. And they will have to think about how
they speak english to be fully understood by the majority of the
participators.

The production of movies and tv-shows was totally dominated by americans
between 1945 and now, but now we see how the rest of the world is
producing more and more programs and movies. The american dominance of
the world's media channels is quickly disappearing.

French used to be a contender. It appears to me that French lost ground
due to France being in some way hostile to the Internet back in the early
and mid 1990's.

The way I remember things, I saw sometime around 1995 a map of the world
with the nations being color coded by some measure of how established the
Internet was. France had the lowest color, same as most nations of
Africa. France looked like a hole in cut out of western Europe on that
map.

A major reason was, if I remember correctly, France being hostile to
privacy of electronic communications to such an extent that one had to
have a license for a modem.

The english language is still strongly dominated by people who have
english as their native language, but that will soon change.

English will become the international language, and will change in
that process. It will be simplified, and special expressions will not
work in an international environment.

Greece was the dominating world power when chemistry was founded,
and we still see greek terminology in the field of chemistry.

Rome was the dominating world power when medicine was developed,
that is why latin is the language of medicine.

USA/Britain was the dominating world power in the era of electronics,
and in the era when the need for a common international language
became
very strong, so english is the language of electronics and the
international
language for the future.

The language english will be reformed in this process, simplified and

That's because more and more people aroung the world are discovering
newsgroups and are realizing that to participate in most, they'll need
to do as the Romans do. But, regarding your statement, so what? You
may have noticed that most of the posters with English as a second or
third language who post to this group are quite conscious of the fact
that they use the language differently from native English speaking
participants and are not at all adverse to taking instruction in the
proper use of the language.

No, we won't. Since non-native speakers will approach English from a
position of ignorance, _they_ will be obligated to learn English the
way it's used by English speaking persons, and for clarification of
poorly or misunderstood meaning will _have_ to refer to source
material, such as dictionaries, written by authorities on the matter.
Such being the case, the language will evolve, as it always has, but
its proper use, technically, will remain unquestioned. Somehow, you
seem to think that this great pool of non-native English speakers is
going to rise up, en masse, with an identical set of preconceived
notions about how the language should be used and that those of us who
use the language will be forced to bend to accept those notions as
proper in order to communicate. Get over yourself.

It's never been a question of enforced dominance, it's been a question
of the availability of local VS imported programming. What's happened
is that as the third world has become more affluent (largely through
the efforts of the native English-speaking world I might add), time
and talent has become available for the production and broadcasting of
local programming instead of the growing of food. So now, Baywatch is
still on at 8PM, but instead of dead air from 9PM until noon,
"Diverciones Bobosas" has the half hour from 9 'til 9:30...
