[CQ-Contest] Split operation in CQ WW CW

[Jukka Klemola]

OK .. hei there ..

Engineers!
Scientists !

Optimize !

Case: a multiplier with a pileup in CQWW SSB 2012 .. any band 160-10.


My suggestion is to start thinking about a scenario the DX is buried
under a U.S. and European pileup, timing is a minute after the spot.
To clarify, let's assume the multiplier is far away from the US.
Like a 3B8 or some other SE African multiplier.
The DX has paid a lot to get there and has set up a good station.

What do you think is the best solution for the contest?

Option 1: DX quits and goes to beach.
Option 2: DX tries calling someone on the same frequency.
Option 3: DX starts S&P and never tries to resume running
Option 4: DX asks up 3
Option 5: DX asks up 5
Option 6: DX asks up and listens 3-7 up

..other option ?


Which is the best for the contest?
How about; which is the worst for the contest?


My choice is option 4.
He would use the least amount of spectrum, the part of the spectrum
would be uniform without unclarity adding holes and the rate with
operational capabilities would function .. so the DX could log
stations. Rate would depend largely on the behavior of the individuals
in the pileup.

Is this thinking far from truth?

> I've worked a lot of station in a DX contest that were operating ** in between ** the DX and his split pileup. Was there lots of confusion? You betcha, however Tom's point is valid. With a wider split the frequencies in between are essentiual vacated and available for others to use.

>> the ruck without anyone having to send "up one" or whatever. I'm sure> Bob was talking about the up 5 splits, not something within 300 Hz or so.What is the difference in spectrum used if the pile is 500 Hz up, or 5000 Hz up?The spectrum used is dependent on the bandwidth of the signals and the spread around a second frequency, not how far away the second frequency is.......once it does not overlap the TX channel width.There might be a logical reason I'm missing. I'm trying to understand the "ruckus" about a 5 kHz split wasting space, when the same exact space is used with a 2 kHz split or a 1 kHz split.If the split is 5 kHz and the stations using that split have emission confined within 500 Hz, they use an extra 500 Hz over single frequency. If the split is 1 kHz, they still use an extra 500 Hz. The use is at a different spot, but still extracts exactly the same total spectrum from other use.If someone is at 7.005 and working simplex and most people have all emissions withi
>  n 500 Hz of width (+ - 250 Hz) they use 500 Hz from 7.00475 to 7.00525 kHz. If they listen up 500 Hz, they simply move that 500 Hz slice up the band from 7.00525 to 7.00575 kHz.If they move it 5 kHz or 100 kHz up the band, they still "hog" the same total space.I'm trying to figure out what people are trying to say, because it has nothing to do with the split distance once it is all outside the one transmit channel width.73 Tom_______________________________________________CQ-Contest mailing listCQ-Contest at contesting.comhttp://lists.contesting.com/mailman/listinfo/cq-contest
