very nice project, you could reduce buttons to two, short press volume+/- and long press ch+ ch-, because if you have many radio stations around then ch- is sometimes nice to have

  Are you sure? yes | no

Thank you. In fact, there are three buttons because three pins were still unused on the ATtiny ;-) Of course, you can change the button behavior in the software.

  Are you sure? yes | no
