Can anyone shed light on why I have a very strong birdie at 28.704?? There are others such as at 25.158, 21.652 but most are outside the HamBands! Is there a fix?? Rig line up is K2+KIO2+KNB2+KSB2+KAF2+K160RX. I have other birdies but they are very low level. But this one always surprises and bugs me when I'm going up the band for the 10-10 net at 28.800 Dave KK7SS K2 #3003
