Thomas, thanks for file.
But, may be you know, how to convert it to *.cfile for
tx_samples_from_file.exe?
Here attached zip with example of *.cfile which Alexander made for me in
somewhere like MathLab, I think so.
Rename zi_ to zip first.

Alexander, may be you know and then you can convert this file or part of it?

Actually you can tune LMS frequensy with 1Hz step to compensate known error.
