Bob,
Respectfully, it isn't that big of a game changer. Many people can already
duplex, and they can duplex quite close in frequency.
It's possible for me, at one site, to null my own transmitter enough to hear
stations on my own frequency while I transmit. The return is not worth the
effort to do that.
I can run 1500 watts steady carrier and hear a reasonable signal on the same
exact frequency as I am on. It gets better as they move off my frequency.
The argument it allows duplex is really pretty lame. Now if the argument is
a remote receiver makes a technically challenged person able to duplex,
then I'll buy that. But.... the advantage of doing that is not that great.
Duplexing is probably worth about 50 contacts or less in a busy 160 contest
with ~2000 contacts.
Having low noise floor or good antennas is worth hundreds of contacts, or
more.
The advantage really being ruled against, despite what people might think,
is someone obtaining a low noise floor or better antennas. What banning
remote RX (within a reasonable distance boundary) primarily does is prevent
people in challenged locations from hearing better, no matter what we want
to pretend it does.

Here we go again with a discussion of technology verses tradition. As we
all know it is already possible to log on line to a remote RX site.
Skimmers are all over the place. Should we allow remote RX sites in
competition? I think not unless extremely limited in distance from the
main site. The full duplex operability and capability is as quoted by Tom
VE3CX "a serious game changer".
I have operated a remote TX/RX site for ten years now and it is a totally
different situation.. The remote function is used for Dx'ing from home as
sufficient bandwidth, latency issues and battery power storage limit
contesting to casual operation. I clearly list on QRZ that _all_ operation
is from the remote site and not from my home address 200 miles away. All
contest operation is from on site and if weather and travel conditions
prohibit getting there I either don't operate or operate with someone else
at their station.
If I operated that remote as directional RX for home operation using a
single vertical with high power that would put me in a better than average
position in SOHP category. Expand the remote RX to multiple locations with
with a good directional High Power station and it would become a super
station. This just isn't right. I realize that all stations are not
created equal, one may have acreage with multiple antennas in an array
combined with low noise levels. It was planned and built that way within
the rules.
I agree with Tree it is another sticky issue. However, I do believe that
allowing separate RX sites during contests depreciates the spirit, time,
effort, and cost of maintaining a well designed competitive station.
Otherwise pick up a cell phone and call "ur 599 in AZ".
sincerely,
Bob W7RH
