Dealer can do it.
I've got about 450 NX-410's in use, have since 2011. I had a radio come in like this about 2 months ago, first/only one. Part was not expensive, but would have required taking the radio apart and resoldering. Didn't mind doing that, but asked our end user if they wanted to pay to repair it. For a 12 year old radio, they decided to replace it. I kept it as a parts donor.
Dealer bench time runs in the ~$85/hour range, plus parts.
Part number is: E04-0416-25 RF COAXIAL RECEPTACLE (SMA)
It's about $7 if you can find a dealer that will sell you the parts.
