That flat ribbon cable between the channel LED and the PLL have issues at the PLL end. If it gets dirty or has poor contact surfaces (common with these radios that I've worked on), then you could have problems with the LED reading incorrectly or the channel selector not working at all.

You do not have to replace C179 with another tantalum, you can also use a regular electrolytic cap. But you should replace it - even if it isn't bad. If it isn't bad now, it will be. Common failure point as already posted by others above
