[Elecraft] RX SHFT=8.0 I.F. Image (16 kHz) Nulling

[Matt VK2RQ]

I'd say you have RX SHFT set to "nor" instead of "8.0". If you set your sidetone to 550Hz, and 8kHz shift is not enabled, then you'll pick up the image 2 * 550 Hz = 1.1 kHz away, which is what you are reporting.

Remember that RX SHFT is a "per-band" setting, so you need to enable it separately for each band.
