[Elecraft] High Current only on 20 Meters

[Leroy Buller]

I have a K3 that seems to have a problem.  I am getting HI CURRENT warning
only on 20 meters.  The antenna is matched.  80, 40 and 15 do not have the
issue.  The current meter on the power supply does show quite a bit of
current (20+ amps) on 20 meters but when I reduce power it stops giving me
the issue on 20 meters.  When I reduce power on 20 meters, the high current
goes away around 65 watts.

Anyone have an idea what is going on?  I do appreciated the help
