Auto spot is fine for rag-chewing, or in contests when there is no pileup,
but it's *not* always best to use when calling in a small pileup. It's
better to call slightly off frequency from everyone else, so use the XIT to
move up or down 100 Hz.
If the DX is working with a wide split, put the *SubReceiver* on the DX
frequency, and use MAIN to set your transmit frequency. No need to press
the SPLIT button any more. Just tap A=B, turn on the SUB, and move VFO A
up to the calling frequency.
Why do it that way?
1. Enabling the SUB gives you an important audio clue that you are in
"Split" mode (even though SPLIT is OFF). If you use SPLIT in the
conventional way, all you get is a visual clue that you're transmitting on
B instead of A. Using the "SUB" technique with SPLIT OFF, you're always
transmitting on A, like you're used to, so it's less stress on the brain.
2. The VFO A knob is bigger, so it's easier to move quickly through a
large pileup to figure where the DX is listening. Using the P3 scope helps
find clear spots in the pileup too. Clear spots are good places to call.
This assumes the P3 is in Fixed Mode, not Center.
3. No need to remember to turn SPLIT off when you are done. Leaving
SPLIT OFF makes it much harder to transmit someplace where you are not
listening. It's easy to remember to turn SUB off, because you can HEAR it.
4. Since the SUB has to be is ON, you are always listening to both sides
pileup when in split (pileup in left ear, DX in right.ear). You can make
the DX much louder than the pileup, which may be helpful. Try setting
CONFIG:SUB AF to BALANCE so you only have to adjust one gain knob instead
of two.
5. If you use SPLIT, CW QRQ mode is immediately disabled, so your CW can
get very choppy (above 37 WPM). Enabling only the SUB, leaving SPLIT OFF,
lets CW QRQ mode remain enabled.
If you really need to use both ears and lots of audio filtering and noise
reduction to hear a weak DX station that is working split, then it may be
better to use SPLIT mode in the conventional way, listening on MAIN,
transmitting on B, than trying to use the SUB. Same if you need to use
Diversity + SPLIT. Otherwise, using the SUB instead of SPLIT has
advantages.
