I’ve got an end fed half wave for 40m strung up in the loft area of my garage, but the way my attached garage works, it’s dry walled up there. I’m having trouble being heard and I’m wondering if this is part of the problem.
Another thing that is working against me is my power supply isn’t delivering max power to my G90, so I need to fix that too!
Isnt the g90 a QRP rig? If so that most likely has more to do with your problems. You may only be able to talk to strong signals. Try setting your preamp gain to -20db to filter out all but the strongest signals.
It, technically, isn’t because it is capable of 20W max.
