illustration below for connecting the FT-891 transceiver to a computer. Be sure to read
the instruction manual of the interface device to be connected to the radio and computer.
r The FT-891 allows for PSK, Olivia, Contestia, etc. digital modes to be sent by the Data
method or SSB. The conventional method is to use USB, except RTTY, however the
Data method allows for more accurate carrier frequency control, which is helpful in a
Contest or DX environment.
