Ive got one for those of you out there with experience in electronics repair. My R-1000 seems to like to randomly start jumping frequency all over the place. A firm "rap" on the top of the rig always puts it back on frequency. It seems to me that when this is happening the digital frequency readout seems to be flickering ever so slightly. By flicker I dont mean it ever goes out, it just seems to dim slightly but rapidly. Anyone have any thoughts? Where can it be repaired? Is it worth it?
