I have a tk-290 that I am trying to progarm. I have some frequencies that work correctly and some that just have a beep that happens randomly when I select the frequency. When I put the radio on scan all get is this random beeping. I know it is not the battery. Any help would be appreciated, I dont know if I need updated firmware or if it is a software programming problem if anyone has an updated version of either that would also help greatly.

Thanks,
