I recently acquired a nice Yaesu FT-890 from the estate of a SK it seems to tx ok (according to reports) but occasionally the display flashes off and on and I lose rx and tx. After powering the rig off and then back on it does OK then later on it does the same thing again.
I have checked the voltage to the radio from the power supply and it is roughly 13.7 to 14.0 volts, all equipment is grounded to a common earth ground and my inverted L end wire is also grounded. My SWR averages 1.3.1 to 1.71 on 10,12,15,17,40 and 80 meters.
Any help on the radio problem would be greatly appreciated. Thanks.
