I'm wondering if any owners of FT-1900r radio had the similar problem:
I've been using radio with no problems for about year and a half, but couple of days ago I noticed that I can no longer switch from channel mode into VFO mode by using [D/MR] button. Corresponding button on the microphone does not work either. After examining all the buttons, I noticed that [SET/Mhz] button is no longer available as well. All other functionality and buttons are operational.
I did send question to Yaesu, but still wanted to try forum, just in case.
