If you press the
8.Press the [ANTENNA 1/2] button to select the appro- priate antenna for the band in use; alternatively, if one
is connected, you may also press the [ANTENNA RX] antenna selection button. Two TX/RX antennas may be connected, or one
ADVICE:
Once you have made your antenna selection, that antenna is “remembered” by the microprocessor in conjunction with the VFO register (frequency and mode) in use when you chose that particular antenna.
9. Press the appropriate [MODE] button to select the desired operating mode.
ADVICE:
By convention in the Amateur bands, LSB is used on the 7 MHz and lower bands (with the exception of 60 meters), while USB is utilized on the 14 MHz and higher bands.
When changing modes from SSB 

to CW, you will observe a fre- 

quency shift on the display. This shift represents the BFO offset between the “zero beat” frequency and the audible CW pitch (tone) you can hear (the pitch is programmed by the [PITCH] knob), even though the actual tone that you hear is not chang- ing. If you do not want this frequency shift to appear when changing modes from (for example) USB to CW, use the Menu item “061 A1A FRQDISP,” described on page 118.
When operating on the FM mode, rotate the [SQL] (Squelch) knob clockwise just to the point where the background noise is just silenced.
This is the point of maximum sensitivity to weak signals. Excessive advancement of the [SQL] knob will degrade the ability of the receiver to detect weak signals.Adjustment of the Sub band
