[hpsdr] RA utility testers, please

[DK4RW]

Joe,

Thanks a lot you for the new version. 

I just started testing. All seems to work as expected:
- signal data are consistent with  the multi meter
- RA data export and import into Excel work for all fields, provided comma
and semicolon are both selected as field separators. For consistency it
would be nice to have the same field separator everywhere, my preference
being semicolon (;). 

Just the "Read data" function results in an error, as already reported by
Georg. If you need another example of a data file and error message, please
let me know.

Would it be possible to write the sample time and the no. of data points
used for averaging into the data file, and read it back when loading a data
file? 

Special characters in plain text files sometimes cause hiccups with some
programs. Just as a measure of precaution, may I ask for replacing the trade
mark character (Line 2) just by (TM).
Thank you.
