I would have to agree with K5GN, that an operator with the same station and
propagation, should ALWAYS have a higher score SOA vs. SO. If not, then
something is wrong !!!!! 
Yes, you might have fewer QSO's SOA vs. SO, but that difference should be FAR
offset by the extra number of multipliers you pick-up from packet (especially
in CQWW). I think setting up the station for maximization of two radios is
the key to minimizing lost QSOs while maximizing multipliers. If you are only
using one rig, best to maximize those EU runs (which we won't have for
another 3-4 years down here !).

Patrick - I disagree. Is single-op really single-op? I know the rules
address only certain aspects of it, but how do you differentiate
someone cooking your meals and bringing you drinks from the guy who
does it himself? How about the guest op who has his "sponsor" running
in and out of the shack all weekend attending to minor station
problems that might arise, rather than the true single op who has to
get off the air and fix whatever is wrong?
I know these are not original questions on my part, but merely fit
in to the whole argument of what is a single op. As I posted in a note 
the other day, there is NO evidence that packet aids the total score
of a top ten type station/operator.
You may be aware that some of the European contests consider a single
op just that - one operator, and with or without packet is irrelevant.

The Yaesu rigs require a resistor on the transceiver TxD line to sink enough
current to bring the logic level low. A 2.2K resistor to ground should do
the trick. Referring to the Feb 93 QST article, insert a 2.2K resistor from
pin 1 of U1 to ground. Then, CT should be able to "hear" the rig.

For some reason, not every Yaesu requires this, but a fair proportion do.
Yaesu tech support are aware of the problem if you get the right guy!

As a quick follow-up to my previous posting on getting
internetters together at Visalia, I have been requested by the
folks who are running the convention to bar-tend for the Friday
eve. cocktail party.  So, pse belly up to bar, identify yourself,
and then maybe we can establish a corner of the room or a spot
poolside for us to meet casually.  I've been considering making a
little sign to attach to my badge that says "I'm an Internet
junkie" or something like that.  But you'll be able to read K6ZH
on my green San Diego DX Club badge in any case.

Be there or be square, 73--Jim, K6ZH
