got the amp yesterday and its up and running.works fb.except for slight
glitch on 160 meters..keeps wanting to go into fault mode if anything over
400 watts out to the antenna.
works fb on dummy load though.
antenna is short for 160 so that might be part of the problem.
Is there an interface cable to allow my Orion and/or Omni 7 to allow either
rig to select the ale 600's bandpass filters?
I was informed not to interface alc cable between the rig and amp.any
comments on this? thanks.
