Split Operation
Often you’ll hear a DX station being called by many
stations, creating a pileup. To ensure that he has a clear
transmit channel, the DX station may say “UP” or
“DOWN” periodically to indicate that he’s listening
above or below his transmit frequency. For example, in
CW mode he might transmit on 14025 kHz, but listen
in the vicinity of 14027 kHz. In this case he would
periodically send “UP 2” (or just “UP”) as a reminder
of where to call him. SSB pileup-split operation is
similar but may occur over a much wider range.
To use split, first hold A > B twice to set VFO B to the
same mode, frequency, and filter settings as VFO A.
Then tune VFO B up about 2 kHz (or the desired
offset). Finally, hold SPLIT. The SPLIT icon will turn
on, and the TX icon will point at VFO B, since VFO B
is now controlling your transmit frequency.
Using dual watch with and without SPLIT
DX stations will tune in the vicinity of their specified
listening frequency when searching for callers. Finding
a clear spot in which to transmit will improve your
chance of being heard. This is where dual watch comes
in. With dual watch ON, you can listen to your RX and
TX frequencies at the same time (pg. 25). You’ll be
able to tune VFO B to find a clear spot, while still
listening to the DX station at VFO A’s frequency. VFO
B can be set up to 7 kHz above or 23 kHz below VFO
A. Outside this range, dual watch is disabled, and the
SUB icon flashes as a reminder.
If an SSB-mode pileup extends more than 7 kHz above
the DX station, you can use a different technique that
allows you to transmit as much as to 23 kHz up. To do
this, simply turn split OFF (VFO A will then be the TX
VFO), and listen to the DX station with VFO B (using
dual watch). This is actually easier than normal split
operation, because VFO A has a larger tuning knob.
Digital Voice Recorder (DVR)
You can record two SSB-mode transmit voice
messages of up to 15 s each, such as your call sign or a
CQ, and play them back one time or with auto-repeat.
This can save your voice, especially in an SSB contest.
For example, you could record your callsign in one
message and a fixed exchange in the other.
The transmit voice monitor should be used so
you can hear DVR playback. This can be adjusted in
receive mode. First, tap AF/MON to select the
monitor level function. Then, while speaking into the
mic, use this knob to adjust the level. Start with 5.
DVR Record:
Hold REC , then tap 1 or 2 on the numeric keypad. The
current message will be erased (4 s). When prompted,
tap XMIT and start speaking into the mic (no need to
push PTT). Tap XMIT again to terminate record. MIC
gain cannot be adjusted during DVR message play.
The gain setting at time of recording is used.
DVR Play:
Tap MSG , then tap 1 or 2. To cancel, tap XMIT or hit
the key. To auto-repeat a message, tap MSG , but then
hold rather than tap 1 or 2. MENU:MSG RPT sets
the repeat interval (1 to 255 seconds).
