Re:CQ 160-Meter Contest, CW 2011 - 2011/01/31 12:23
Hi Victor,
I have no SO2R intra band 160m setup and it is really missing to improve my score.But it is not so obvious to built such a thing. I have to built a separate RX antenna as far as possible from the TX one and have this RX antenna with a deep nul in the direction of the TX antenna+very sharp input variable filter and/or a phasing unit picking a sample of TX signal. I will only be able to construct that when I have a definitive TX antenna and you now that I have the project to make a phasing TX antenna system. By the way, I have finished the new antenna direction keyboard (4*8 directions keyboards with control leds+8*push-button keys on the same array than my former on whose picture is on this website) just before the contest and tested it during the contest (I will send you pictures soon). This time the 8 circle RX was not performing as well as during the ARRL 160 and actually I worked mostly with the beverages, I have some tuning work to do, perhaps I will built my own controler (the current one was bought) to have a better control on the tuning and maintenance. So, as I posted last year, before constructing more phasing systems, an efficient central control unit had to be built.
About the ID, yes I worked one and only one he called me during the second night. That shows again how much a SO2R would be an help : if you are not permanently calling CQ, you will miss some S&P-only unique mults and if you never S&P you will miss some run-only mults.
By the way Victor, again, I am very impressed by your results relatively to your very modest area/volume for antennas.
