Table 5-1 | Transceiver interface
Under CAT interface control, the amplifier follows the VFO "A" frequency changes only.
The ACOM 04AT and 06AT automatic antenna tuners follow the frequency of the
amplifier.
If your transceiver has more than one VFO, as well as in SPLIT mode, use VFO "A" for
transmission and for tuner control. If the amplifier frequency does not change over the
CAT interface, make sure you are using VFO "A" on the transceiver, as the amplifier CAT
interface only uses VFO "A" data.
