[Elecraft] K2 Receive tuning "blips"

[Jim Miller]

As I tune the K2 across the band I get periodic little "blips". They aren't 
birdies and they don't hinder reception. As I sit either side of the 
frequency where the blip occurred there is no apparent signal or 
interference. They actually tic the S-meter a few notches as well. The blip 
occurs when the display changes from 3-4 on the least significant freq 
digit. So there's really no way to "sit" on the frequency.

I'm guessing this has to do with the way the PLL and VFO tuning interact.

Is it normal to hear such little blips? Or do I need to do some debugging?

Currently I get it at 7014.73 as I transition to .74.

Likewise at 7019.73-74, 7024.73-74 and 7029.73-74.

Interestingly I only hear it with my antenna attached and not when open or 
with a 50ohm dummy load.

Antenna/feedline: 88ft doublet @ 50ft elevation remoted 60ft from house. 
50ft of 450ohm windowline to SG211 at mounted directly below center point. 
60ft underground feed via RG213 from SG211 to K2.

73
