Using the transceiver

3-12 HF SSB transceiver user guide

Selecting the sideband or AM (USB/LSB/AM)

The

USB/LSB

button on the control panel switches between

upper sideband (USB), lower sideband (LSB) and AM (if

fitted) depending on the current channel settings.

You can select USB or LSB for:

• channels set up with the

sideband option (lower or

upper sideband selectable, see Using View Channel

Options mode on page 3-31)

• all receive-only channels

• free-tuning in Free-Tune Receiver mode.

You can select AM for any channel if the AM option is

enabled (refer to the HF SSB transceiver reference manual,

Chapter 7, Password entry to enable transceiver options).

The AM setting allows you to transmit on AM to AM stations

that are incapable of sideband communication. The AM

setting automatically operates as USB on receive.

You can receive AM transmissions on any AM, USB and

LSB setting. For an AM broadcast you may find that

switching between USB and LSB improves reception.
