Hello I'm trying to put the NYC DoITT UHF system into the radio. I'm downloading in from RR using freescan, when it's downloading it shows the step as being 6.25. After it's downloaded into the radio I check the step on the radio and it shows it as 12.5 and it also changed the control frequencies, I tried to changed the step to 6.25 but it's not even there as an option 12.5 is the lowest step. According the the manual the radio is capable of handling a 6.25 step. I have the latest firmware installed. Am I doing something wrong?
