Danny,

I have had intermittent problems with the programming switches on my 631 TX. Sometimes I am able to switch models and sometimes I cannot. I know the problem is in the right switch when I move it up. Is there any known issues with this?

I bought the radio new at the LHS about 2 1/2 years ago. I don't fly all that often. I had the problem shortly after I purchased the radio but then it "went away." Last night I was able to switch models to program a new one, but after that it would not let me switch back to the original model or to enter programming mode.

Thanks

Doug

There aren't any known issues, however it sounds like your system will need to come in for service.
