[TenTec] Orion CW keying with v 2.054 & 2.055 using Acom 2000

[Carl Moreschi]

The only way to get an arc fault on an Acom is to actually have a place
where the RF is causing an arc.  I have had arc failts with my Acom 1000 and
I always find some place where the antenna or feedline is improper and
causing an arc.  I would check your antenna switch or antenna for a place
that is too close to ground and causing an arc.
