Well this has happened to me just once. On Friday evening I was 
downstairs and my station was all set up ready to start CQWW 
upstairs. I was aware of what seemed to be someone tuning up - 
seconds of tuning audio - but didn't bother to look in the shack. 
When I came up a bit later just before getting some pre-contest 
shuteye I found that the K2 had no audio and no signals. Not sure 
what else was wrong, but it may indeed have been in transmit mode. 
Panicking of the worst, I switched it off then on, and all seemed OK 
again. I did speculate that the audio stage had overheated from the 
tuning chap's loud audio and it needed a power up reset, but that is 
pure speculation. The K2 continued to work perfectly for the whole of 
the contest (40 hours of operating (!!) and the rig powered up right 
through to the end), but you can imagine it got the adrenalin going 
here....

As for the contest, running 5W QRP, I had 837 QSOs, 210 total band 
countries (77 countries overall) and 50 band zones. Claimed score is 
298,062. 10m didn't really open and conditions were not that 
brilliant, but there was plenty of DX around to work.

Mention has been made of abbreviated CW - A for 1, T for 0, and N for 
9 are universal. U for 2 is less common but also used. EA8ZS was 
taking it to the limit and sending VV for 33 which is pushing it a 
bit as it sounded like 44 (but there are only 40 zones in CQWW!) and 
you already had to train your ear not to misread the S in his call as 
an I.... When using logging software it is academic as it puts in the 
correct zone for you anyway. Use of abbreviated numbers in contests 
with serial numbers causes no end of problems however...
