[Elecraft] K3 Receive Sensitivity Consistency

[David Little]

When I turned the K3 on this morning, I decided to listen to 60m, to get
away from the contesting.
 
As I went through the bands from the 2 meg frequency I had been monitoring,
when it got to the 5 MHz band it seemed to be a bit deaf.  
 
Volume was considerably lower, but signal on the P3 looked consistent with
the other bands.  
 
Going into the Menu and bringing the Receive EQ to +16 on all 8 frequencies
did not restore the volume level.
 
Using the Band switch, toggling back down to 75m brought similar results;
lower receive level. 
 
However when going back to the original 2 Meg frequency and manually tuning
up with the VFO, the sensitivity and volume remained consistent all the way
up to the 5 Meg freq that I was trying to monitor initially.
 
After that, going through the spectrum using the Band Select switch yielded
consistent results.
 
When using the VFO, I was looking for a magic relay click, or some crossed
frequency threshold that triggered a return to sensitivity, but there was no
degradation as long as I was going up the band with the VFO. 
 
Serial Number 5063; Anyone else seen this before?
