I just got my first HF rig, an FT101E. I plan to set up a half wave dipole for 20 meters in the next 2 weeks but right now I have a 2 meter antenna already in place. My question is, as long as I leave the mic disconnected, the heater off, the mox/vox off, and all of those switches in a row there off, would it be ok for me to see what I can hear using the non resonant antenna for receive only? Can I hurt the receiver just listening around on 20/40/80 to see if I can hear anything? I've downloaded a manual and I am trying to learn as much as I can about this radio while I study for my general ticket, but there is SO much to learn.
