The formatted text file "Kyodo.Chn" contains the frequency and channel information.
It is intentionally formatted with spaces, not tabs.
"Kyodo220.Chn" is included as an example.

It is IMPERATIVE that the column labeled "Spacing" be evenly divided into 750.
For 220 frequencies in Texas, we use a 20 kHz spacing.  Since 750 divided by 20 is not an integer, we use 10 as a "Spacing".
For 25 kHz or 12.5 kHz, just enter 25.0, or 12.5.

Enjoy!
