[TowerTalk] Working with HFTASweep data

[Randy Farmer]

Thanks for the tip, Dan. Unfortunately, I can't get the HFANT utility to 
accept the data from the HFTASweep files. I get either complaints about 
improper antenna name format or invalid character in field. I've done 
considerable fooling around with the data files and can't figure out 
what the problem is. I can copy the new data and paste it over the data 
in one of the sample files and it gives me an error, but doesn't 
directly say where it is. I haven't taken the time to check all 32,760 
entries in the data file to see what (possibly non-printing) character 
is causing the upset. It sure would be nice if I could find a spec for 
the exact data table format, but no luck there looking through the 
documentation. Guess I'm stuck with Excel.
