There's no stopping any avenue of broadband delivery regardless of its
need in the marketplace, or how worthless the content. And dated
technolgies such as amateur radio and shortwave broadcasting don't
stand a chance of surviving in the face of the broadband Goliaths,
because bandwidth, any bandwidth, available by any means, equals big
money. So enjoy the MW and HF spectrum while you can, because there's
no stopping the encroaching digital hash. We've been degrading it for
years with QRM anyway, with every new switching power supply or RF
generating unit added to our homes, and millions being added every
day. Change is inevitable. I'll surely miss scanning the HF bands
with my SX-28, my HQ-120, my homebrew regen, even my Sony 7600. I love
HF and I listen to it almost every day. But the "cheese has moved."
If you live well outside of suburbia, or on the open sea, you can tune
or use what's left of HF. Otherwise, you should look elsewhere for
your radio fix.

Are you saying broadband access and HF radiation must necessarily go
together? If so, why?

Good q. I have what can be called broadband 'net access (DSL with 768k
down / 128k up), and I have more trouble with the hets generated by ISDN
(it's a combo ISDN/DSL thing with a splitter) or rather the radiation
from the apparently unshielded ISDN cable from the ISDN NTBA to the
telephone base station than any other "telephone line" related effects.
Something that does radiate heavily, on the other hand, is my (cheap)
Fast Ethernet switch, also via the wiring, followed by my computers.
(OK, *that* stuff is in the same room as my SWL eq't. I think I needn't
mention that I always "pull the plug" on all possible sources of
interference before SWLing - all the computer stuff and the DSL
modem/router.) Powerline Communications has been proven to be
inefficient for any larger number of users and thus is good for inhouse
comm at most. I don't see any good reason to promote it except wanting
to get a number of phone calls and letters from angry hams and SWLs.

I should *really* be drinking less, it seems. (But less than nothing?

[1] OK, it's a lame old joke, plus I wouldn't even see double even when
drunk, but what the heck.

As a commodity, the HF spectrum can be more greatly exploited for profit as

a means of delivering data bandwidth than as a means of mass communication
or 2-way comms. Broadcasting via terrestrial MW/HF/VHF/UHF transmission
can be virtually replaced by broadband/digital, cell or satellite
technology anyway. Broadcasters look forward to the day when they can
mothball their multi-kilowatt transmitter sites and the engineers they pay
to keep them running. Imagine the savings in electricity alone!
I have a buddy who, thru his Sprint wireless internet connection, can
listen to RealAudio sites from his laptop while driving in his car. It's
just a matter of time!

MW/HF isn't much bandwidth. 30 MHz tops. As a comparison, the FM spectrum
alone is 2/3 of that . Or 5 TV channels. There's nothing favoring
broadband data transmissions on such low frequencies. Efficent antennas are
very large. Directional antennas aimed at one point source are almost
impossible. There's alot of interference from natural sources such as
thunderstorms. Radiated interference can come from halfway across the
state, or half way across the world. VHF/UHF beats MW/HF for broadband
communications on all counts.

OK. Let's say electricity costs 10 cents a kilowatt hour. A 50 kW
transmitter uses 5 bucks worth of electricty an hour. Imagine how much more
poor Rush Limbaugh could make if transmitters weren't bleeding the network
dry!

Now that I think of it, the real money would be found in creating automated
talk show hosts. One or two more advances in computerized vocalization, and
Sean Hannity is on the soup line.

Oh. What part of the HF/MW spectrum does it use?
