[QUOTE="noonereallycares, post: 1063777, member: 14179"] With my limited skills, the best I could offer is the XLS file attached to this post. With 600+ regions, it is a bit hard to document. I basically ran a bunch of regular expressions to strip out the data and then moved the "new/old" value to the end of each row. Then I used another regular expression to have excel calculate which one was higher. Luckily, none of the changes involve 9A, so I was able to simply replace that with 99 to allow excel to do a lookup to find the frequency. You need to use the frequencies in the order that they appear in the columns (left -> right) to avoid having old frequencies replace new ones during a scan. Alternatively, just allow for all possible frequencies and not create area-specific groupings. If someone loses a channel, then it means that the next rescan will skip the now dead frequency and only find channels on the good ones. Edit: I just stumbled across this spreadsheet of change over dates: [url]http://www.communications.gov.au/__data/assets/excel_doc/0011/161012/Copy-of-Channel-Change-Timetable-13-Feb-2014-2-Tabs2.xlsx[/url] It also lists only the channels that will be changing, so that may also be useful. If there are any questions, just shout. [/QUOTE]
