[Elecraft] K3 Spur on 160??!!

[Joe Subich, W4TV]

In this case it looks as if the AC0C has a simple SDR with an I/Q
balance problem.  In both cases reported the "spur" is equal distant
on 1,842.65 KHz.

For example, a very strong carrier could mix with another strong station's CW to create "ghost" signals (third-order intermod) for the duration of the carrier. Another possibility is demodulating a strong signal due to a spur in the receiver's local oscillator. Such scenarios are much more likely during heavy contest activity.
