[Elecraft] PSK31 -- ghost image:

[Martin AC6RM]

I've just started playing with PSK31 with the K2 and a rigblaster Nomic. 
I noticed something strange today.  A station appeared strongly just above
14071 kHz, but the station also appeared almost 2kHz higher in the band as
well.  I'm using digipan 1.6 which allows you to watch two QSOs at the
same time.  They were both the same station -- character-for-character. 
Is there something wrong with the way that I have set up my equipment?

Tks in advance, and 73,
