Operation
USING SUB VFO B
The Sub VFO works in a similar manner to the Main VFO, with which you should be familiar by now. The Sub VFO provides simple split (transmit/receive) fre- quency operation via the combination of the MAIN VFO’s RX and TX LED/Buttons and the SUB VFO’s RX and TX LED Buttons, and, more importantly, dual- channel reception via the [DUAL] button. We’ll get into those in a minute, but first let’s look at how to control the Sub VFO.
Frequency, mode, and Clarifier data can be trans- ferred from the Main VFO to the Sub VFO by pressing [AuB], but don’t forget that this will overwrite any set- tings that were in the Sub VFO previously. Also, the contents of the two VFOs can be swapped (with no loss of data) by pressing [AuB].
Most selections for the Main VFO can also be made for the Sub VFO directly, by pressing [SUB(CE)] right before another keypad key to select a band, or before a mode button to change the Sub VFO mode (displayed below the Sub VFO frequency). When you press the [SUB(CE)] key, the entire display for the Sub VFO will blink, after which you have five seconds to press an- other key. Note that to switch VFO registers in the Sub VFO, you need merely press the [SUB(CE)] key fol- lowed by the key for the same band that the Sub VFO is already on.
rTo set the Sub VFO (if it currently is on 7.000.0 MHz LSB) to the 14 MHz band,
press [SUB(CE)] ð [14(5)].
rTo change to USB, press [SUB(CE)] ð [USB].
rTo set the Sub VFO’s frequency to 14.225.00 MHz USB in one step,
press [SUB(CE)] ð [ENT] ð [1.8(1)] ð [10(4)] ð [3.5(2)] ð[3.5(2)] ð[14(5)] ð[USB] ð[ENT].
Unlike the Main VFO, with its
Of course, you can tune the Sub VFO using its tun- ing knob, and use faster tuning steps by holding the [FAST] button (below the left side of the main tuning knob). You can use the large DOWN(q) and UP(p) keys (in both normal and
About the only things you cannot do with the Sub VFO (that you can with the Main VFO), are store it directly into a memory, and set the Clarifier. For these functions you need to swap it with the Main VFO first

DUAL RECEPTION

Dual receive operation opens up exciting operating possibilities for split operation, contesting, and chas- ing elusive DX stations. For

There are 12 BPF networks in the receiver front- end circuitry, each covering a particular segment of the transceiver’s full receive range. SUB
Main and Sub VFO Audio
The AF GAIN knob controls the Main VFO’s vol- ume level, and the smaller SUB AF knob controls the Sub VFO’s volume. The effect these controls have on receiver audio can be changed, and is configured us- ing menu selection
Separate - The receiver volume for the Main and Sub VFOs is adjusted independently. This simply means that the AF GAIN knob controls the MAIN VFO- A volume and the small SUB AF knob controls the Sub VFO’s volume.
