The current, experimental version of tk2 works with IC-R2 models which employ 10 kHz or 9 kHz spacing in the AM Broadcast Band (e.g., USA, Japanese, European, and other models). It permits expanded .005 - 1599.995 MHz frequency coverage (except cellular bands) for memory channels and can:

Read a memory image from an IC-R2 receiver or a disk file. Display data from a memory image and let a user change various settings. Add descriptive labels to memory channels and banks. Sort memory channels by frequency or label. Swap pairs of memory banks. Import memory channel data from a csv or ICF file. Export memory channel data to a csv file. Write the results back to the radio.
