tk2 is open source, multi-platform software which configures the
ICOM IC-R2 wide coverage receiver. It runs on Linux, MacOS X,
BSD, UNIX, Windows (95 and later), and other operating systems.
Changes in version 0.7 include:
1) Memory bank channels may now be edited within tk2. Channels may
be changed, deleted, inserted, or swapped with adjacent
channels. More comprehensive changes can be made by exporting
the channels to a CSV file, then using a text editor or
2) Added a duplicate frequency check.
3) Fixed a bug which truncated interstitial frequencies,
e.g., 470.3125, and showed them without the proper last digit.

I don't warrant the software, though it will cost you nothing.
