Overall the contest had a lot of activity. The first night was much better with conditions very good through the night but the second night had about 5 hours after sunset that seemed as though signals were considerably attenuated. Both nights we had EU openings at EU sunrise that lasted 2.5 hours Friday and 1 hour Saturday which is outstanding for our location. Conditions were also very good to JA both nights. We worked 179 JA and 78 EU which is the most EU we have ever worked in the CQ160 contest. It looks like the coming low sunspot cycle will be great for west coast to Europe conditions. This year we had a new operator, Jon, NR7T who was new to N1MM contesting but did an amazing job and will be a valuable asset to the team in coming years. We had a bit of a scare when we turned on the amplifier Saturday afternoon and had the step/start circuit fail sending sparks and smoke into the room. We didn't have time to repair it or spare parts so we just put a short circuit across the burned out resistor and hoped the inrush current would not blow anything out. Needless to say, when the amplifer started up OK, we did not turn it off for the duration. We had good weather both days but cold at night. Early Saturday AM the thermometer registered 2F. Fortunately, Jack, WA7LNW had brought wood for our fireplace which kept the operating room nice and cozy. Riki, K7NJ kept getting so warm that he opened the door to let some of that 2F air into the room to cool off. We have good antenna separation and with the low off frequency noise transmitted by the K3s we can hear pretty good on our multiplier station even when the CQ station is transmitting. However, some noise is still detectable which makes it a challenge to copy signals at the noise floor. So for next year I am thinking of designing a narrow band transmit filter to reduce this off frequency noise to below band noise on the multiplier receiver. I wonder if anyone is using this method now. The station is perfect for Multi operation because it has 3 fully independant TX gain antenns which makes the multiplier station a lot of fun to operate. Hope to see you all next year when conditions should be even better. 73, Al K7CA Station power: Generac propane generator Rig: K3s, K3, Alpha amp, Command amp TX ant: 8 EL broadside/endfire vertical array 70 degree or 250 degree 6 EL broadside/endfire vertical array 45 degree or 225 degree 10 EL broadside/endfire array with 4 verticals N, NE, E, S, SW, or W and 6 verticals either SW or NW RX ant: The TX arrays usually receive better than the beverages but we have independant beverages NE, E, SW, W, and NW
