[Elecraft] K144XV observation

Whilst listening to SSB signals on 114MHz using the K3, K144XV, and P3 I noticed that I can receive perfectly resolvable signals 11kHz either side of the main signal.  Further investigation revealed that the spurious signals are every 11kHz either side of the wanted but reducing in amplitude the further away from the wanted signal I tune. The levels are -40dB, -60dB, -80dB on the HF side and -50dB, -60dB,-80dB on the LF side.  All levels are referred to the wanted signal and are my best guesstimate from the P3 display.  This is only on 144MHz and does not manifest itself on any other band.

The only other observation is that the frequency calibration offset is +5.34kHz rather than the +2.86kHz marked on the transverter.  

If any one has experienced such observations and how to overcome them I would appreciate your input before I contact our friends at Elecraft.
