Dear team,
when I use "QT GUI Digital Number Control" to display a frequency I see
some "special effects".
Below 128MHz, it works fine but above I get wrong display data:
ok:
Input 128.001.000Hz -> Display = 128.001.000
not ok:
Input 138.001.000Hz -> Display = 138.000.992
Input 137.999.000Hz -> Display = 137.999.008
I simulate that input by using Gpredict via tcp port 4532 but found
debug messages ok.
Does that depend on the QT GUI Digital Number Control and the way it
converts numerical data types, since (128 = 2⁷)?
Can I adjust that module by my own?
73, Tom, DJ6TB
