In a word, Jim, NO.
No, the internal tuners of iCOM radios (and those of Yaesu, for that
matter) can typically tune out a VSWR of only 3:1 . That means that on
bands other than 80M, your half-wave (80M) dipole will have a widely (and
wildly) varying VSWR that the '756 internal tuner will not handle.
Please stick with using your external antenna tuner if you want to continue
using the dipole on "all bands" and make it easier on your '756. PLUS,
the output of your '756 is an unbalanced feed point, and you'll need the
tuner and/or a current balun to provide an interface to your balanced
ladder line.

Subject: [Icom] Antenna Balun/IC-756PRO
I have an 80 meter half wave dipole fed in the center with ladder line. I
have been using an external antenna tuner for years to tune this antenna to
all bands.
If I use a BALUN and then coax into my IC-756PRO, does the internal tuner
have the range to tune this antenna on all bands above 80 meters?
