Sorry, you need to research the history of the so called
"assisted" categories. In the late 70's and early 80's
before clusters you would see an occasional entry in multi-
single labeled "K7ZZZ + net." With the early packet cluster
software starting in the early 80's "N1XXX + packet" began
to appear. In both cases, multi-single was the correct
entry class as "net" and "packet" meant participation by
However, as clusters began to spread and more people began
to consider using the cluster, some operators started to
question the "fairness" and whether it was appropriate to
make a single operator compete against "tag-team" operators
that could keep rested bodies in the seat for the full 48
hours. While sponsors understood the fairness issue they
also understood that "packet" did not belong in the single
operator category - not because of the spots but for the
same reasons that "+ net" was put in multi-single in the
first place - due to the participation by other individuals.
An alternate was needed and the "assisted" class was born.

... and the power categories are already quite broad. Even
if a simple tribander was "assigned" an arbitrary gain of 6 dBi.
Low power + Yagi would be much closer to high with a dipole
than to low power with a dipole. If the real antennas were
a short vertical or hidden random wire (typical CC&R antenna
situation), Low power + yagi would certainly have a significant
advantage over high power/CC&R.

Why should contest sponsors reward one technology (antennas)
and punish another (skimmer)? Technological advancement of

Again, that is incorrect. "Packet" is permitted in all classes
except "single operator" because all of the other categories
permit participation by other individuals. "Single operator -
assisted" is simply a special case of "multi-single" that
recognizes the difference between a one operator and a "tag

There is no "SO-unassisted" category - only "single operator"
and "single operator - assisted." Assisted is, and always
has been, shorthand for "+ net" or "+ packet." The issue is
the participation by "another individual" and not how that
participation takes place.

The same can be said about the application of computer logging
that made SO2R as we know it today possible. In the early
days you did not hear much about SO2R (or separate "stations"
for each band) because calling CQ, checking the dupe sheet,
filling out the log, etc. consumed too much of the operator's
time. The advancements in computer speed and sophistication
that have made SO2R possible (practical) are simply being
continued into the area of identifying stations.
It has been possible to monitor a few frequencies at a time
for several years ... that computer technology makes it
practical to scan more frequencies faster is the nature of

Skimmer does not eliminate that skill - unless you accept the
data blindly - it simply adds one more source of data for the
operator to use as he sees fit.

So what? There were top operators who did not want to use memory
keyers or computers. When others adopted them, everyone was
forced to adopt the technology. There are top operators who
do not want to do SO2R - they understand the disadvantage they
accept by not using SO2R.
Where the technology does not represent participation by another
individual it does not violate the rules of the single operator
category. Every operator should have the right to decide for
himself if he wants to use that tool. For contest sponsors to
change the rules to disallow one technology (skimmer) while
continuing to permit other technologies (SO2R) that are even
more "disruptive." That change would effectively give one
group of operators a "veto" over the way another group of
operators choose to configure their station... it would be
as if I could tell you what you could not do with your station.

Exactly - because there is no participation by another person.
It is the additional person that represents the difference
between "single operator" and "single operator - assisted"
not the information received or the "channel" over which
the information is received. As N0AX has written - get over
the term "assisted" and focus on the real difference - the

Again, the information does not matter - I get that information
by tuning the receiver. The only thing skimmer does is tune
and decode faster that the human can just like computer logging
dupes and logs faster than the human operator.

Sure ... but make it realistic and have both operators running
at 60+ per hour on another frequency and decide which of the
stations they hear/confirm from the other list are multipliers
and worth potentially losing a run frequency to work.
Contesting is not simply working stations from a bandmap. If
it was "assisted" stations would beat the other "single op"
stations in every contest.

No, category decisions should not be made based on the effect
they will have on the competition. They should be made based
on the rules and the traditional criteria for the rules. If
the criteria are to change, the changes in criteria should be
applied uniformly - for example, if technology is added to the
list of criteria all technologies (computer logging, SO2R,
Antennas/EIRP, etc.) should be reexamined and the technologies
that make the largest impact (SO2R and EIRP) should be the
appropriate candidates as the "decision makers."
Specifically, if 'technology' is to be the distinction, we
should be looking at EIRP (QRP < 10W < LOW < 300 W < HIGH),
number of simultaneous receivers, single/multi operator
(including "participation by another person"), and number
of simultaneous transmitters.

I do not believe that ... it could simply be because sponsors
have not had the courage or desire to enter the "technology"
debate. Once sponsors enter the area of technology it opens
a whole new can of worms ... much like the current debate but
with many more dimensions. Once sponsors enter the area of
permitted/disallowed technology and the appropriate level of
the technologies, the sponsors have to be careful that they
are not picking winners.

Again, there is no "SO-Unassisted" class. The single operator
ops are there because they do not want the participation by
any other individual. Technology, no matter how it presents
the information is not an individual.
