No lock means the radio is not tuning to the frequency the personality is giving it. This is either because you have an SC4 file that is 'adjusting' your frequencies after ProGrammer has written them to the radio (not likely) Or the radio itself has a serious alignment issue that is causing it to not lock.
The solution to this is verify that it functions with a brand new clear personality with 1 channel in it like the weather service radio, and see if it locks then. If it still error 401s, then you will need to realign the radio/repair the VCO to get it back in spec.
