I suggest that you save your radio's memory contents using the free Icom software before you load any of these files into your radio.  That way you can always put your radio back the way it was before you started.

These files include most of the Digital repeaters from Orlando to Tampa and up I-75 to Dayton.  I included the repeater that I know about that are likely to be in my path.  All of the files can be manipulated and edited with the Icom programming tool for the IC-80AD and IC-880H or a spreadsheet program like Open Office.

The CSV file type contains information and commands specific to one port on one repeater.  The format of these file names is <last three positions of the callsign>-<port ID>.csv.  For example, the file with commands for W4RNT port B is named RNT-B.csv.  The Icom software can import these into a "Memory CH" under "All" identified by the block of memory numbers within.  These  blocks of memory channels are named 0-99, 100-199, and so forth down to 900-999.  When these blocks of memory channels are imported or exported with the Icom software no Bank information is included.  That information can be added later in order to group memory channels into convenient memory banks.  In the csv format the information can be manipulated with a spreadsheet program.  This is convenient for working with columns of data.  The Icom software will allow you to copy, paste, add, and delete entire rows.  The spreadsheet software will allow you to do that with columns.

That's about it.  Good luck with these files.
