[TenTec] cw overshoot

[Mark Erbaugh]

Bob,

Thanks for the confirmation.  I was running barefoot.  The old SB-220 isn't
set up for QSK.

I did notice that the display on the Orion also dimmed.  I am using an
Astron 35 amp supply, so I don't think I was taxing the power supply. I'm
using the power cable that I used to use with my Pegasus (same rig end
connector) and that has the AirPax magnetic breaker (20A) in line, which
wasn't tripping.

73,
Mark
