[CQ-Contest] [NCCC] TXRX of the Future is here Now!

You don't have to have a computer at the remote
for all other radios.  On the contrary, you
can get a Lantronix remote terminal server
(~$70, Digikey) and make any radio's serial
port look like a LAN connection.  So the built
in LAN port is merely a convenience, nothing
to get excited about.

Also, I don't see any big problem about having
a computer at the remote site unless it is running
on solar panels or something where the power consumption
is an issue.

The built in audio over IP is convenient, but the latency
is a showstopper for contesting, if you do it over the
internet  (I don't know about point to point links).
I experimented with operating my Galt station remotely from Cupertino
during the recent DX contests.  The delay of several
hundred ms each direction was a rate killer.  I could
still make contacts, but I wasted a lot of time trying
to anticipate when to respond.  And there was no way
I could call CQ.  I found myself "cheating"
by listening on the Cupertino radio to get rid of the
receive delay.  For the record, I was using SM5VXC's
"IP sound" program for the audio over IP.  It is much
better than Skype.

Subsequent to that, I installed a phone patch in Galt
and measured the delay over a POTS phone line.  Essentially,
zero delay.  Of course, you can connect the phone patch
to any radio.  I will be experimenting with this setup
in some future contests.

For the record, I am using a TS-570 for the remote radio.
