Contesting Online Survey

Survey Question Current Survey Question

Recently the RDXC committee reclassified P3F to high power from low power without publicly providing strong evidence that any infraction had occurred. They concluded was that the contestant was running HP on 80/40m but not full-time, just 10 minutes here and there without any convincing evidence. It appears they used the RBN as their source of information. Should the RXDC contest have to publicly provide convincing evidence before reclassifying a station from LP to HP?

Randy, K5ZD, wrote a sidebar titled " Convergence and Change" in the 2015 CQWW CW printed results in CQ magazine. He wrote that the "convergence of personal computers, Internet access, DX clusters, and CW Skimmer have changed the nature of CW contesting". He goes to say that it is "more difficult to police the line between the single operator working alone and those who are using the assistance of DX spotting." In light of this convergence and change is it time to recombine SO and SOA into a single category?

You're organizing a Multi-Multi entry -- keeping 6 bands covered for 48 hours. How many operators do you think are needed, and why ?

Multi-Multi operations
We usualy try to get the most people posible
some are good operators the others like antenna work and others are prepairing food
there are so many things to do.
So my vieuw is always when covering so many bands The more hands there are how lighter it gets, Do remind the grumpy people afther 48 hours off contesting :o)

number of operators for a multi-multi
I have quite a bit of experience with this subject.
The minimum number of operators required is the number of band-hours open divided by 48.

For J3, the number of band-hours is about 180 in this part of the sunspot sycle. Therefore, the minimum number of operators is 4.
At J3A...

In CW WW CW 2000, 4 ops produced 20M points.
In CQ WW CW 2001, 6 ops produced 27M
In CQ WW PH 2001, 3 ops produced 15M

With a really good bunch of ops, four is enough. If the adrenalin flow is a little low, a fifth will help. Six is a luxury.

A lot
Why? So I can rest.

Any time I'm at a M/M, I'm the one elected to do things like solder PL259's, since nobody else knows how to do it properly. "What's that? Ummm, I'm in the middle of a run, my rate was 300 and it's dropping by the second. What'd you say? Solder a connector? Oh, okay..."

Multi Multi M6T
At M6T there is an informal approach. Even though band has
a "captain" which is the band builder and "owner", there is
still some moving around by 1st/2nd operators across the
The band captain typically has a second op who both
operates and assists in the build for that band.
As the station is "field day" style, this is the only way we
can managed two systems per band in the time available.
This normally gives us about 10-12 persons for the build and
the contest. Although 48 hours operation plus the build before
is always tiring.

Multi Multi Ops
I voted 10 - 13, and I guess that to some extent it's also a matter of how much hardware you need to keep running. I've been seriously involved in multi-multis at M6T and 9G5AA / XT2DX, and have been lucky enough to operate one CQWW SSB from W3LPL. Each of these operations are different. In the M6T environment we don't rely on getting all multipliers from packet and there's a strong need for some folks to be combing the bands looking for mults / QSOs on another receiver - this needs extra bodies, and is obviously what happens at LPL as well. There's also the requirement to have someone available to spell anyone responsible for keeping the station running when something blows up (not that it ever does...). Having said that, I personally like the concept of having a main op on the band who really owns the band, though some of our ops prefer to work in pairs.

From Africa we're limited in the amount of hardware (antennas and rigs....) that we can take and set-up, and so the 'correct' number is somewhat smaller since there's still a need to ensure that everyone gets enough operating in. Having said that, there were only 6 of us this year from XT2DX and by Sunday morning we were all just about comatose after all the work travelling & setting up in the sun!

M/M Operators at KC1XX
At KC1XX, recruiting top-notch operators is a perennial problem for us. As as result, we usually run "lean"--one main operator per band with typically three backups, or a total of nine operators. The main ops generally like to do "ironman" efforts with a small amount of backup help. Personally I find I really need to stay on my band full-time to maintain a good "feel" for what's happening on the band. The only band that really needs a second operator is 20 meters, which stays open the full 48 hours.

Number of Operators
I think 10-12 "Full Time Equivalents" is optimum if you have a station that is going to be working the pileups at a high rate, CQing all the time. During the overlap periods, you will need to be fully staffed. During very high rate periods, you may want two operators on each band. Certainly, you want your operators to be fresh during those periods. So getting a little shut-eye is a Good Thing, as well. When all is said and done, something around 2 ops per band is about right. Any more and you have a lot of dead time. Any less and somebody is overworked. Plus, its a LOT more fun when you have a band-mate to work with.

Having organised a couple of DxPeditions to Lord Howe and also another 3 MM from the main land it really boils down to how good the ops are! A club event that is done for the fun of it can leave you a bit flustered with guys on the mike working at rates under 100 per hour in pileup situations but to encourage the new guys you need to turn a blind eye! The best op I ever saw was Keith VK2AKZ (SK) whose wife was Japanese he acheived constant rates over 250 per hour on our 1979 VK2ATZ operation, at that time we had 10 ops. One of the ops was Rudi Breznik manufacturer of the EMTRON DX 2000 linear amps :-)

I asked this question, so I'd better make a comment! I've been organising Multi-Multi entries since 1995 (GM7V), and the number of operators involved has been getting less each year, by choice. You can choose the best operators, those who work well in a team, and they get to know the bands better in the 48 hours. Here in Scotland, all 6 bands are active only at sunrise and sunset. Personally I want to be either operating or sleeping, not hanging about waiting to operate. Multi-Multi with only 5 or 6 operators is more efficient, more fun and more tiring!
