Anybody who listens to AM radio at night around here is likely DXing.


I just ran a multi-book report on your area, called LA / NNE, and found that
less than 10% of all radio listening by 18-54 year olds is to AM. #1 and #2
stations are KLVE and KIIS, both Wilson FMs.


Did you do this after you "graduated" from college?


When did you learn to be such a poorly-mannered ass?

d'Eduardo,

Thank You Once Again For Reminding Us
That We Don't Count As Sellable Numbers.
we are just plain old radio listeners




Yes and the sooner you realize that, the happier you will be. You
shouldn't expect the FCC or the National Association of Broadcasters
to care about a hobby (distant AM listening) that only represents less
than 0.01% of the audience.

Actually Eduardo wrote a very intelligent, very informative post.

YOU are just too stupid to understand it.

Do you think that those kids listening to a ball game from a

clubs? Or the trucker tuning across the dial to find something worth
listening to ....



Kids today use their computers to listen to distant stations, not
radio.

Truckers use XM or Sirius, not terrestrial broadcast.

You are living in the past, but everybody else has moved into the
future with Broadband internet, and Satellite. Time to wake-up and
smell the truth.

Most truckers have Satellite now... an excellent solution for drivers who
move from market to market, too.


How's that GPA holding up?



Hey old man, did you pick out your coffin yet? Are you going for
metal or wood?

Well, Wildblue and Hughesnet are the two major providers of satellite access
in the US and they both use two way satellite connections. They do not use
the phone. Both offer higher upload speeds than a conventional phone.

Makes one wonder what else you don't understand.



(1) Don't be rude & insulting.

(2) I looked-up two-way satellite communication on wikipedia before I
posted, but it said the upstream is limited to only 2.4 kbit/s.
That's a LOT slower than a 56k phone line connection.

(3) If wikipedia is wrong, please provide a citation so I can update
it. Back-up your "higher upload speeds" claim.

Streaming audio certainly isn't DX, but I fully support Wimax and
internet radio because (1) they're going send HD radio into the
dustbin and (2) they don't destroy a huge swath of spectrum.


It doesn't? According to wikipedia, the EU has set-aside 300
megahertz of space! That's a heck of a "huge swatch" of spectrum.
15 times larger than what's allocated to FM, and 300 times
larger than the AM allocation. I call that huge.


300 MHz isn't beans at 2.4 GHz (or higher). It's also not a lot when you
consider that the bandwidth will be used by thousands or more users. Once
you break it down into individual slices of bandwidth for each of those
users, it doesn't really allow for much. Wireless N for your home network
passes up to 200Mb/s..

you don't think that takes a lot of bandwidth?



Uh. Yes. Which is why I was rebutting the comment "Wimax doesn't
destroy a huge swath of spectrum."

Your posts show you don't have experience with what you are talking about.
If you don't like that being pointed out, too bad.

Go to the Wildblue or Hughesnet web sites. You'll find they offer 128kbit or
higher upload rates.

Streaming is not DX. Also, where do you think these rural listeners are
going to get broadband internet access that would allow them to listen
to these streams? Ain't gonna happen, because nobody is supplying
broadband outside of cities. (hint: satellite internet doesn't handle
streaming audio for beans, since the backhaul is still via telephone
modem, and the lag doesn't allow for enough FEC... )


Can you explain "backhaul is still via telephone modem"?


Sure.

Downlink is from the bird. You still have to be connected to a phone line
for your uplink (unless you want to pay beuxcoup bux for an uplink
transmitter). Thus, you get good download speeds, but the return path is
a slow 56Kb/s phone modem. This causes long ping times, which causes poor
forward error correction and nasty slow uploads.



Since the two primary providers of satellite internet service in the US do
not use phone lines for the uplink, all of their customers must be paying
the big bucks. (While their service isn't cheap, they have no phone uplink
option.)

Actually using a phone line would reduce the latency issues relative to a
satellite uplink.

This is another area where you don't know what you are talking about.

Yes. My colleague does the VHDL, I do the linux drivers.

I would never have gotten my CS/Maths degrees without knowing what
they are.

- Synchronous DDR?


Yes.

- PCI Express?


Our board that we are designing is 4 lanes.

- Flip-flop?


you are JOKING, right?

- What does GCLK mean in the context of FPGAs?
- What are constraints?

This is just a small sample of what I know, because this is what I
work upon every day..... but I suspect a lot of it you have no clue
what it's about. And that's fine. Because I don't expect one person
to know everything there is to know about EE.



If that is your idea of a test, you need to go back to school -- a
real school, not some trade school, child.
