Announcing 'hifi-am', to discuss High Fidelity AM tuners and hobbyist transmitters
 

Hello,

I've created a discussion group (mailing list) to discuss high
fidelity AM tuners and hobbyist transmitters. Appended below is the
more detailed group description.

To subscribe to this group, either go to the group home page (at
Yahoo) and subscribe there (you will need a YahooID):

Looking forward to seeing you there!

Group Description for hifi-am:
==============================

The purpose of hifi-am is to explore the possibilities of high
fidelity AM tuners and hobbyist transmitters for medium-wave (or
better known as the broadcast band, appr. 520 to 1720 khz.)

Although most commercial AM broadcasts are definitely not high
fidelity (due to various factors including, in many countries, audio
bandwidth restrictions), there are nevertheless a few commercial
stations which broadcast with audio quality approaching high fidelity.
For example, in Australia, because the number of stations is fewer and
the country quite large, many stations broadcast with quite wide audio
bandwidth, approaching 15 khz.

There is steady growth in interest (in the U.S.) for non-licensed
hobbyist broadcasting in the BCB (per FCC "Part 15"), which is
restricted to 100 milliwatts and a three meter antenna (among a few
other minor restrictions). With a high efficiency antenna, it is
possible for such neighborhood broadcasting to be heard about 1/2 to 1
mile from the transmitter. There are quite a few progressive and
alternative stations broadcasting this way. For a wonderful example,
see Radio KMTZ.

More importantly, it appears there is no specific restriction on audio
bandwidth for Part 15 transmissions. Thus, if this is true, the
broadcasts can approach high fidelity (15 to 20 khz audio bandwidth.)

Although discussion can focus on the general topic, it is hoped this
group will catalyze the development of hobbyist kits for high fidelity
AM tuners (digital, solid state, and tube) and for high fidelity
low-power (Part 15) AM transmitters. It should be fun to consider the
many possibilities.

I have been using Yahoo Groups, and before that Clubs for years and never
have received even so much as a single Spam related to Yahoo Groups. I do
receive a few Spams every year related to my use of the Yahoo financial
sites, but I don't think I have received anything yet in 2004 related to
that.

Some time back I was going to subscribe to the Yahoo R-75 groop. When I
saw how much information they wanted, I bailed out.

Yes. I found that to be true. It may be that people already in
their system were grandfathered in without a problem. It's the
new folks that get nabbed. When Geocities/Yahoo Groups was easier
to access in the past, I found their particular form of popups to
be ingeniiously eggregious. Now, you can't even take a look
without agreeing to be abused.

I've tried to sign up lately, omitting certain sensitive
information. The information that they wanted was both invasive
(date of birth, etc.) and a spam setup. The system won't pass the
application unless those sensitive fields are filled -- I made up
false entries for them. I also gave a competing webmail address
so the spam would go there. No matter what, their system
repeatedly refused to register me, returning a bogus message
every time (I reserve a special place in hell for bogus error
messages and the bogus bogusers who write them). I believe it's
because it recognized myrealbox.com as another free webmail
service, and won't play without a true wide-open juicy spam
socket (a bona-fide ISP address). The same thing happened to my
son. Yahoo's terms of service and privacy policy make the price
pretty clear, too; you gotta pay to play.

I don't feel that it's worth compromising my privacy and sanity
to make use of any service that they provide. Too bad. Perhaps we
need an ethical alternative to these jokers in return for a small
fee. Someone's got to pay, after all.

So, are you just saying that all I have to do is make up a phony
email address, like ? And that this
will work?

Alternatively, can I get a Hotmail account without setting myself
up for abuse?
