Listen to 21345.4 and 21237.1 at the same time.
Falls under the "what is not specifically prohibited is allowed" rule ?
And
For those that missed it....

21345.4 on one audio channel, 21237.1 on the other audio channel.
Sorry for the late reply to this but after reading the comments on
Steve's post and the replies I felt the need to comment on this.
Some background...
K4BAI and myself have been operating from the PJ4G station as PJ4A for
CW contests since the mid -2000's. A few years ago the club started
using a remote receive antennas a good distance away from the transmit
antennas. Two short towers - one pointed to the USA with a tribander
and a SAL loop at the same location. There is also a EU receive site
with a tribander pointed to Europe and also a EU beverage. Because
these receive antennas are connected via coax they are legal within
the rules for both the ARRL and CQWW contests. In fact W4PA has
visited us several times during their PJ4Q trips for CQWW DX CW and
has never made a comment that this wasn't within the rules. This
answers the question some people had on how you can have two stations
on the same band without much interference.
The 2nd point : Maybe N2IC is confusing the ARRL DX rules with those
of CQWW ? Alternating CQ's on the same band are prohibited in CQWW
contests but not in ARRL contests.
CQWW Rules :
Only one signal on a band is allowed at any time. When two or more
transmitters are present on the same band, a hardware device MUST be
used to prevent more than one signal at any one time. Alternating
CQs on two or more frequencies on a band is not permitted.
ARRL Rules:
I looked at the ARRL DX rules and the HF General Contest Rules and I
don't see anything that prohibits alternating CQ's on the same band. I
don't think the comment W3LPL made about ARRL DX is correct... or I'm
missing finding it in the rules.
The only ARRL contest that has this rule is IARU for Multi_Single
entries :
*4.3.2.1. *Alternating CQs on two or more frequencies on the same band
is not permitted.
Note : 1.2.General Rules for HF and VHF contests take precedence over
General Rules for all contests.

PJ4G was Multi-Multi so the only rule that would apply to them is :
*2.3.3.Multioperator Multi-transmitter:*
*2.3.3.1. *A maximum of one transmitted signal per band at any given
time.
There are lockout devices at the PJ4G station. The 2nd in-band radio
shares the same amplifier and antenna as the run station. There is a
device (I think Ameritron makes it?) that allows you to use an AL1200
with two radios and isolates one when the other transmits. So it would
be impossible for them to have two signals on the same band at the
same time.
