I can be short about this one (from 3830):
It just kept on going and I felt strong. I made a lot of use of the second radio for which I installed my second antenna. This antenna can be seen here:
During the night I slept for a few hours. I was not really tired but the rate was so low I decided to get a nap and be fit for the last seven hours.
For now (10 days after the contest) I am the first non-LZ on 3830 in CW HP. Last year I was second with 600k points. I now have 1000k.
Apart from tons of fun and a good score, I feel confident for CQ WW CW.
