HD radio question

[Svt40]

When a radio station is selected (more often on HD stations) what are the numbers next to the HD symbol Such as "HD 123". Usually one of those numbers is highlighted.

They are the sub-stations assigned to the FM station. Each analog FM station that broadcasts HD radio can broadcast up to 3 "sub" digital channels.

Yea after work I went out and just started playing with knobs and stuff.

The tuning knob changes between the different stations on that single HD frequency.
