[TowerTalk] Arc fault Acom 2K

[W1JCW John]

Have a strange problem in the shack.

Run the same antennas and had no issues, put in line my Yaesu 5000 and palstar AT.
All antennas tune flat 1:1 but when I run QRO the Acom 2K comes up with arc fault even with low drive of 20watts.

I can place a load at the end of the coax outside and have no issues but when I got to any antenna 260' center fed dipole or a vertical I get a fault and the amp shuts down.

Sounds like an RF issue but why now when nothing has changed outside?

Have not seen anything like this in 40yrs I've been operating.
