The enable/disable swith on the back of the 3000 controls the 3000's built-in deinterlacing circuitry. If you have it enabled, you'll get 31.5 kHz video from the 31kHz port unless you go into the 1280 "superhires" mode. If you hook up a VGA monitor to that 31 kHz port, you will get rid of the annoying flicker that you get at the 15 kHz port when running in interlaced modes like 640 * 400. There are some monitors like CBM's 1960 that will scan all rates from 15kHz to 31kHz, but they are more expensive than a vanilla VGA monitor.
