CAT Commands

From The Unofficial FT-897 Wiki

CAT lets you control the radio from a computer - a better description will be put up sometime. For instant reading see the manual, it explains it and the serial format and parameters required.

Undocumented Commands

Name	P1	P2	P3	P4	Opcode	Notes
Read EEprom	MSB	LSB	0x00	0x00	0xBB	Returns 2 bytes, the specified address and the 'next' address. 16 bit memory addressing, unused memory returns 1 byte (for me 0xf0).

Interesting Memory Locations

Address	Name	Values
0x0068	VFO	0x80=VFO-A 0x81=VFO-B
0x008D	Split	0x00=No split, 0x80=split
