The 897D has no port for downloading firmware updates, like on the 950. The only way to change that channel is either through the "wideband" mod, or sending the radio in for a fix. So far as I'm aware, there is no factory modification available at this time.
At least, from what I read in the Federal Register, this frequency change does not invalidate the FCC type acceptance of any 60 meter capable radios of current manufacture.

There is a port internally to update the firmware. The chip supports 100 writes (not a typo and its not the external i2c eeprom). In order to do this youMessage 1 of 3 , Feb 10, 2012View SourceThere is a port internally to update the firmware. The chip supports 100

this you first send a loader program which erases what is there (so you

You don't have to reverse the entire firmware either, same method used for
software apps or other embedded products. The bandplan is a vector array
on most every (all?) Yaesu radios. The jumpers just tell it which vector

A clever person could use idapro (supports that chip) and locate that table
