80m ideas?

Hi, everyone-

A group of us will be in the ARRL DX contest this weekend...we're using it 
as a training run for the WPX Contest...we have a new operator who needs 
some real-time experience with CT and phone pileups.

We've also done some antenna work around here, which will open us to a 
new possibility: running stations on 80m. Since none of us have experience 
in that venture, we could use a few pointers concerning the band plan for 
DX, specifically Europe and Pacific. 4/5of us are active contesters, and 
all of us are Dx'ers, but we've never had any reason to work DX on 75 
phone, so we're all ignorant of the band plan (we all work CW on 80m).

Any advice for some folks new to 75 SSB? 

E-mail preferred, to keep traffic on the reflector to a minimum.

73, See ya this weekend as W9SZ.

Derrick, there's more to the story. If memory serves, the musicians
promoted their own music on a local (low power AM?) broadcast radio station.
Perhaps this is where Danny's one time penchant for QRP began. Seems
that it was a show about amateur radio. As I recall another player went by
the name Homer Heterodyne (the late K7RA). Wonder if they taped any of the
radio show!

You have his theorem wrong.  His theorem derives a minimum signal to
noise ratio necessary for stuffing the bits through a band limited channel.

You could use his theorem to predict that those high speed modems were
actually possible.  You could also use it to predict that they probably
wouldn't work on your typical 20M SSB voice channel using 100 watt
radios and dipoles across the country.

Since radio channels tend  to be noise limited, as opposed to bandwidth
limited, radio modem designers look at the situation differently than phone
modem designers.

EU big guns -  Please check 10 meters up until your sunset !  Give the
well-equipped stations in western USA a chance to work you on scatter beaming
to South America around 1600Z-1630Z.  1530Z is too early.
