This is a show-stopper of a question. I have been running PSK for a number of years, and have never observed anyone running split. With an exceedingly narrow-band mode such as PSK31, it should not be necessary, although occasionally someone will drop down right on top of your offset, either because he can't hear either side of the QSO or because he is being careless. QRM happens. Occasionally one sees people operating with multiple sidebands (an overdrive problem), and occasionally there will be the usual AGC pumping by very strong stations, but normally even at hyperactive times, the 4 kHz or so that PSK operators self-allocate is plenty to accomodate everyone. Sometimes (as in contests, hint hint) RTTY and/or CW operators ride roughshod over PSK.
I would actually recommend using a separate program (I prefer FLDIGI) for digital methods, as the degree of oversight of the local part of the spectrum is better (unless you are operating with a P3). After a fair amount of floundering around, I have settled on FLDIGI driving a SignaLink USB box into my K3/P3 rig, but this is perhaps a matter of personal preference. I have used this on a K2, a Flex 3000, and the present K3/P3. FLDIGI runs on a very wide variety of platforms (WIN XP, WIN 7, MAC, Linux, etc), and is a very friendly, uncluttered control program. I use it a lot for RTTY as well as PSK31, PSK63 and other digital modes. If FLDIGI is "too fancy," then either DigiPan or Airlink Express work well and require much less computer power. DigiPan works just fine on my netbook. There is other software, but much of it is badly "overgrown" and represents very poor programming practice IMNSHO.
