Prepare the KX3 for the KX3-2M or 4M Module
The KX3-2M or 4M PC board mounts on top of the KXAT3 Antenna Tuner board. If you do not have the
KXAT3 option installed, your kit will include an adapter board to install in place of the KXAT3.
If you do not have the KXAT3 Antenna Tuner installed, disconnect the HF antenna cable from the
main RF board as shown in Figure 15.
Figure 15. Disconnecting the Antenna Cable from the Main RF Board.
Route the antenna coax cable across the RF board, between the toroidal inductors and alongside the
standoff exactly as shown in Figure 16.
