USING SUB VFO B

SIDEBAND DIVERSITY RECEPTION

Here you receive a single AM signal through the two receivers, each receiving the opposite sideband. Skywave-propagated signals often show phase distor- tion in this mode, but it gives you a view of the entire passband, from which you can then select the best sideband for listening (or for SWL Dx’ing, you may want to listen to both sidebands at the same time, to get the best copy). On groundwave signals, where the phase of the sidebands is likely to be the same, there is an interesting sense of depth to the signal.

To tune in a signal using this mode, you should have stereo headphones connected to the front panel PHONES jack, or an external stereo amplifier con- nected to the rear panel AF OUT jack.

rSet the Main VFO to either LSB or USB mode, and tune for zero beat on the desired signal.

rPress [AuB] to copy this mode and frequency into the Sub VFO, then press the mode button to select the opposite sideband for the Main VFO.

rIf using headphones, set the headphone mixing scheme to the Stereo 1 mode, and press [DUAL] to activate dual reception. Adjust the AF GAIN control(s) to balance the volume of the two receiv- ers.

If interference is present on one of the channels, you may have to turn its AF GAIN control to suppress that channel (or press the green “RX” switch/LED to disable the receiver with the sideband experiencing interference). Otherwise, try changing the headphone audio mixing scheme to Stereo 2 or Mono in the menu selection for different effects (or try settings with simi- lar effects on your external amplifier). Although you don’t get the “stereophonic” effect in the monaural mode, the two signals are still mixed, offering the potential for much better copy than in regular AM or even single- sideband ECSS modes.

BANDWIDTH DIVERSITY RECEPTION

This mode involves receiving the same signal through two different bandpass filters. The frequency and mode of each VFO is the same. The main receiver provides a narrow bandpass, and the sub receiver a wide bandpass, resulting in a spatial perception 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 amplifier are recommended for this mode. To set up the trans- ceiver for bandwidth diversity reception:

rSelect the desired mode on the Main VFO, and the press the [NOR] or [NAR1] button (its LED will light up).

rTune to the signal of interest.

rPress [AuB] to copy this mode and frequency into the Sub VFO, then press the [NAR 2] button to se- lect a narrow filter for the Main VFO.

rIf using headphones, set the headphone mixing scheme to the Stereo 1 mode and press [DUAL] to activate dual reception. Next adjust the AF GAIN control(s) to balance the volume of the two receiv- ers. If using an external amplifier, adjust its balance control.

You also may find it interesting to try the SHIFT and WIDTH controls (on the Main receiver) for some inter- esting effects.

Before retuning, remember to press [DUAL] to turn off dual reception.

VFO TRACKING

To have Sub VFO B track the Main Receiver VFO while tuning (with dual reception on or off), simply hold the [LOCK] button depressed.

With [LOCK] depressed, the “TRACK” indicator ap- pears when the main tuning knob is rotated, and the Sub VFO tracks the Main receiver. Release the button to resume normal tuning.
