A year ago, signals of at least S3 on my FT-817ND were common. Now they are weaker. As well, I get the impression that the signal polarity has changed. Formerly, I could hold my Arrow dual-band Yagi with the 2 m elements nearly horizontal and still hear the satellite. Now, I have to turn it nearly 90 degrees, sometimes changing the orientation more than once during a pass. Some of that I might attribute to my operating a portable station within a residential area in the city, but I definitely noticed a significant difference between what I hear from AO-51 now and what it was before the satellite was flipped. 73s Bernhard VA6BMJ @ DO33FL __________________________________________________________________ Yahoo!
