This is not XP Polytone, this is a ham mode. I am not at my home computer to light off software and find out which mode it is, but it sounds like it might be either Olivia or one of the MFSK modes, my bet is on MFSK-16 or something along those lines. Of course the MFSK modes sound very much like XP. Check this page for some examples:
http://www.k3dcw.net/index.php?p=1_4_Digital-Mode-SamplesThis frequency is in a section of the ham 40 meter band that is heavily used by digital modes. From about 7025 to about 7100, depending on the region of the World you are in, you will find MANY digital modes, often mistaken for things like XPA. And by the way, the signals will be in USB mode, not LSB. On the ham 40 meter band audio is most often, by convention, in LSB, but digital signals are in USB. You 7096 LSB would also be about 7093 or 7094 USB.
