FYI, the AT-6666PRO can be set to remember the mode and other user settings, per individual channel. For example, if CH 38 is always LSB, CH 06 is always AM, and 27.555 is always USB, the radio can automatically change the mode for you, when you arrive back those channels. (Use the PUBLIC (PD) setting). See the user manual.
No mode scrolling / button cycle required.
