I bought an ALinco DR 590 dual band amature radio at a hamfest. It is a
mobile. Got it home, hooked it up, everything on the display lit up. I
mean everything, even things that were not supposed to. The frequency
number has stange lines in it. It was not usable.

Came back later and it started working fine even made soem contacts
with it. Used it for about 20 minutes, no problem. Put the radio away
inside.

Hooked it up last night to try out some antennas and it did the same
thing. I played with it for an hour to no avail. Took it inside and
took it part way apart, did not see anything, maybe soem pinch wires to
the display but could not tell. Put it back togther. Hooked it up and
it worked fine. left it in the garage last night. Hooked it back up
this morning before going to work. It worked fine.
Am I crazy? What could this be?
