[Elecraft] SWL question

[Wayne Burdick]

Hi Marc,

The K3 automatically selects the lowest-frequency low-pass filter  
available based on the VFO frequency. It also automatically chooses  
the optimum ham-band filter or KBPF3 filter.

The list of frequency boundaries is quite long. Suffice to say that we  
carefully optimize filter selection to preserve the K3's excellent IMD  
characteristics, especially IP2. (This refers to the radio's ability  
to reject images resulting from incoming signal sum/difference  
products; this is very important for SWL use.)

73,
Wayne
