I was trying to open some of the chanalyzer .wsr files found on the wiresharkbook.com website. I assume these files are from an older version of channalyzer as I cant seem to open them with Chanalyzer 4 or lite. Couldn't seem to find the answer in the forums or support anywhere although. Is there software still available that will open these files? If not, it looks like there are plenty of sample interference recordings I can find here.
