The tuner in my IC-746 (original) has stopped functioning on 80m at 3.900 MHz and above and also on 40m at 7.200 MHz and above. Does anybody have suggestion(s) as to possible locations of cause(s) for these malfunctions? * * * * * * * * * * * * 73 - Mac, K2GKK/5 * * (Since 30 Nov 53) * * Oklahoma City, OK * * USAF, Ret (61-81) * * * * * * * * * * * *
