Sorry, another question, If I turn in fsbus my freqency for my com1 radio, only the last two numbers wil turn, but not the first 3 numbers, how can I program this in Fsbus program so I can change only the first three with a switch en with another switch the last 2 numbers??

It depends on the options selected in the FSBUS object like "round","fractional","step",etc).You have to set them in the correct manner to obtain the desired result.Look at the examples provided by FSBUS.
