Bandwidth Diversity Reception
This mode involves receiving the same signal through two
different bandpass filters. The frequency and mode of both
the Main band (VFO-A) and Sub band (VFO-B) are the
same. The Main band (VFO-A) can be set up for a wide
bandpass, using the [
WIDTH
] knobs, and the Sub band
(VFO-B) for a narrow bandpass, resulting in a spatial per-
ception of the channel. Although any mode (except FM)
can be used, CW offers the widest array of choices, and
perhaps the most startling effects on crowded channels.
Stereo headphones or an external stereo speaker are rec-
ommended for this mode. To set up the transceiver for
bandwidth diversity reception:
ˆ Select the desired mode on the Main band (VFO-A).
ˆ Tune to the signal of interest.
ˆ
Press the [

quency into the Sub band (VFO-B).
ˆ If using headphones, set the headphone mixing scheme
to the “
Con1 Con1 Con1 Con1 Con1
” mode via the Menu item “ 091 rout
HEADPHN ,” and activate dual reception.
ˆ Adjust the [ AF GAIN
] knob(s) to balance the volume
of the two receivers.
ˆ Now try manipulating the [ SHIFT
] and [
WIDTH
]
knobs to observe the interesting effects of bandwidth
diversity.
