CQWW RTTY - DQ4W / TM6A MULTS ANALYSIS

Just for the fun I took the BCC station, DQ4W claimed score published on 3830 for reference ( see http://lists.contesting.com/archives//html/3830/2006-09/msg00957.html )
Although they did more QSO's (2485 vs 2321), which is quite normal taking into account their M/2 category, I was surprised to see that we managed slightly more mults (590 vs 581) despite our poor location, and quite modest antennas.
Multipliers by type... States/prov is our weak point !

Of course, it could be explained by a collateral effect of the M2 category, but what is interesting is that we managed more zones and DXCC's but less states/prov. The effect of our poor take-off toward NA is quite obvious in the following graphs: On 80m, the 8 degrees blocking does not look as a major handicap, but it becomes dramatic on 15m... Conclusion: F6KAR maybe a decent location for many contests along the year, but certainly not for an ARRL-DX all-bands !

Multipliers by band... 15m is our weak band !



States/provinces by band: The effect of 8 degrees blocking !

Condx better than expected taking into account the very low SFI
(who could expect 124 countries to be logged this weekend in TTY?)
15m opened to Eastern-states on saturday, and 20m remained open quite late.
Unfortunately the propagation deteriorated on sunday, but the E's openings allowed 31 countries and 7 zones to be logged on 10m.
Good first night with 2 hours at rate >80, but bad second night with rate droping around 20 between 2 and 5z and very few NA-stns. No major technical problem experienced, just a few glitches with PA switching and software behavior, both probably due to some RF-feedback.
Finaly a decent score for the solar minimum, thanks to DX-peditioners and all participants for creating such a huge activity on the digital bands (and even a bit outside ;-) !
