Hello, An Happy New Year ! After selection in Config Menu FLx ON/OFF, the new choice work, but only 1 time; after, each filter is selectable when activating the XFIL button; i want to exclude the 2.7kHz (i've a 2.8kHz one) from the list, but it reappear. Any idea ? TNX for a reply. 73 QRO, Rudi, HB9ARI
