What’s wrong with using an ATU?
Dipoles are resonant at one frequency (and its harmonics). If you want to work both the CW and SSB ends of the band you’re going to have sub-optimal VSWR somewhere (unless you change the wire lengths).
This graph shows VSWR for my 80m dipole (without ATU) …
Also, modern ATUs have very little thru-loss. When I switch the KX2’s internal ATU in or out at the dipole’s resonant frequency I see no difference in VSWR or received signal strength.
