... stuck in the middle with PSK31! Field Day 2008 is in full swing!
Here's a 24kHz wide segment of the 20m band, centered such that 12kHz = 14070kHz. The vertical lines on the left are CW transmissions. The paired vertical lines on the right are RTTY (simple 45.45 baud FSK with baudot encoding), and the cluster of lines at the center are PSK31 (31 baud PSK with varicode encoding).
Captured with speclab, my FT-857D, and an IF out modification to get 24kHz wide sections.
Also, here is a closeup of the PSK31 activity, from 10kHz to 14kHz:
