First weekend of the 2010 ARRL 10GHz Cumulative Contest

It's that time of year again, this weekend I started off up in New Hampshire on top of Mt. Kearsarge in FN43bj. I was joined by W1FKF, W1EX and N1ZZN (who was there to climb the peak). We got into the park a little early, and were up top and setup by 9:15. The WA1VVH 10GHz beacon was on and VERY loud on Saturday, which was very helpful. We could hear the Mt. Greylock beacon, but it wasn't very loud (I think it's lower power).

We had a great day, I broke my previous records of 22q's with a grand total of 27 for Saturday. My best DX was down to WA2FGK in FN21, who was there, but very weak.

Sunday W1FKF, W1EX and I met up at the Westborough water tank at FN42fg. The weather forecast was for heavy rain, so we knew it wasn't going to be a long operation. I got there a little early and got the liason system up and running. There weren't many people on 2m, which wasn't a good sign. W1FKF and W1EX showed up shortly afterwards and the three of us had our systems up and running within 5-10 minutes. We managed to work about 6-7 stations, the best DX was K2KIB at Highpoint New Jersey, in FN21. That was actually impressive since all three of us were looking through a tree and a bus!

Shortly afterwards the rain started, we made the last 2-3 contacts then called it quits around 9:30. When I got home I brought the 10GHz rig into the house and decided I might try doing some rain scatter. There was a lul in the rain, so I set up on the back porch which faces N-NW. Once the LO was somewhat stable I tuned around and didn't hear the VVH Beacon. I added about 15 degrees of elevation, and boom! There it was! I was hearing WA1VVH/B very strong, about S5 on rainscatter. I could hear it in about a 15 degree arc on the azimuth and about 20-30 degrees in elevation.

I went into the house and tried to get the guys up on Kearsarge to run with me, but they were in a heavy rain period and decided to wait a little while. About 20-30 minutes later we tried sending to each other, but never managed to complete. When I went back to the beacon, it had almost disappeared.

I then downloaded the rainscatter program by K0SM, and learned how to use it. I could see the storm in Eastern New York state that was causing the scatter, it was in the same 15 degree arc that I was hearing the beacon on.

I never ended up working anyone, but it was a good lesson in learning how rain scatter works. I'm more equipped to take advantage of it next time it happens....

The next weekend of the contest I'll be down on the Cape for at least 1 day, and I might spend some time down in CT and RI along the coast line.
