operation on the Main (VFO-A) receiver will resume.
Note: Please remember that, while the [B] mode button is blinked (five seconds), any
mode or band changes will still be applied to the Sub band (VFO-B), whether or not
Dual Receive is engaged.
Quick Point: 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.
Advice:
When operating in Dual Receive, the manner in which the audio is fed to the left
and right sides of your headphones (Stereo, Monaural, or Mixed) may be configured
using Menu item “088 rout HEADPHN” (see page xx).
When changing modes from SSB to CW, you will observe a frequency 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 changing. If you do not
want this frequency shift to appear when changing modes from (for example) USB
to CW, use the Menu item “060 A1A FRQDISP,” described on page xx.
When operating on the FM mode on the Sub band (VFO-B), rotate the SUB [SQL]
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
SUB [SQL] knob will degrade the ability of the receiver to detect weak signals.
Adjustment of the Main band (VFO-A) Squelch is accomplished using the Main
[SQL] knob.
Using Headphones for Dual Receive
To take advantage of dual reception, you will want to connect stereo headphones to the
PHONES jack. Like the AF GAIN control, headphone audio mixing can also be
configured as desired from Menu item “088 rout HEADPHN.” Three audio mixing
schemes are selectable as follows:
SEP:
Audio from the Main band (VFO-A) receiver is heard only in the left ear, and
Sub band (VFO-B) receiver audio solely in the right ear.
Con1: Audio from both Main band (VFO-A) and Sub band (VFO-B) receivers can be
heard in both ears, but Sub band (VFO-B) audio is attenuated in the left ear
and Main band (VFO-A) audio is attenuated in the right ear.
Con2: Audio from both Main band (VFO-A) and Sub band (VFO-B) receivers are
combined and heard equally in both ears “Monaural” mode).
