K3 #768 working well except for sub-receiver which has suddenly become deaf. Did I bugger about with a menu setting? Not essential but I would like to get it back. Managed to enter WPX RTTY and plenty of cw pile-ups daily. Worked Chris G3SJJ for first identified K3 QSO. NA around 2200Z is strong. Will QRV ~ 7.101MHz. Cheers, Terry G4MKP
