Without fully knowing what TRackBox is, it looks like an issue related to floating point estimation. There should be some more info on the web about the phenomenon, but basically floating point numbers are stored as a sequence of sums, not as exact numbers. It may be that the number you desire can't be represented exactly by a floating point data type.

That's just a guess, but it resembles something I ran into with floating point data types not too long ago.

Hi to the list, it is a while that I've noticed that my trakbox when it terminated to track the satellites it should put my radio in parking frequency which should be:

RX_Freq : 1296.500 TX_freq :144.800

But I always get:

RX_Freq: 1296.499.9 TX_freq: 144.800

How you can see, the RX_Freq is 1 Hz down. I've tried to set the RX_Freq to 1296.501 But when it parks, it goes to: 1296.500.9 Can anybody explain me what happens? Thanks in advance.
