This year the contest runs from 2100 UTC on November 21st till 0259 UTC on November 23rd. The rules can be found on the ARRL website....HERE.
I'm looking forward to this contest so I can try out my brand new addition to my antenna arsenal, a 148' inverted L which runs across my backyard approximately South-West to North-East. It's about 60' off of the ground up in my trees. Over the past two months I have been experimenting with various wire antenna designs, and none of them have come close to my 80m OCF Dipole up at 50' from the ground. Most signals have been 3 to 4 S units down from my dipole. We will see how this antenna does and do a full report after the contest.
