In Win-Test, all frequencies have a 100 Hz resolution. Without going 
into gory details, it is related to the way it is stored in memory and 
in the files to comply with all bands Win-Test can handle (up to 241 GHz).

One easy way is to use the string.format function :

catCmd = string.format("FA%08d;", data)

assuming FA accept 8 digits data (I don't know exactly what TRX you 
intend to use, and the specs of the format).

More info on the Lua string library here :

But, as a reminder, even if you set freq to 14123.456 MHz this way, 
Win-Test will further still consider it as 14123.4
