This is really weird. I am on 160 meters. And I am running my amplifier. If I transmit using the amplifier, for some reason the EESDR screen on #3 monitor goes blank if I use 1100 to 1200 watts, yet will remain on monitor 1 which is the MB1.If I transmit with less than 1000 watts, no problems whatsoever. This is the first time I have experienced such a thing It does not happen on any other band except 160. Could this possibly be an RF problem? I don't really have RF problems, but then again, I really don't transmit that much on 160 either.
Any thoughts on this?
