[CQ-Contest] Leading zeroes

Hi,

Just one point of view from the other corner of the planet.
During the last 3 contests I entered (for only a few hours each I admit) over the last months, I tried the 4 strategies : send just "n" (the number), send TTn, send OOn or send the full 00n.
In all cases some operator were confused and asked me for a repeat (not counting the cases with "very low" S/N ratio). The lesser repeats needs were for "n" and "00n". The worst case was OOn because if there is QSB the other stations can wonder if it was a 2 or 8 instead of a O.

Now I've decided to go with the full numbers, not cut numbers, because 95% of the QSO I make during a contest are "on the edge" with QSB or QRM (I run 100W to simple antennas) and this is what gives the best "signal recovery" possibilities. I very seldom can run high rates where a few seconds lost in sending 0 really matter.
If I were located closer to Europe, or if I had better antennas, giving me stronger signals, perhaps I would go without the leading 0.

73,
Yan.
