[Elecraft] KX3 VFO tuning noise...an observation...

[zendoc at netspace.net.au]

Hi Group,

	FWIW, I have an observation about the KX3 VFO tuning noise.

	 

	I assembled my  #2511 (absent any options) from the kit.   Over
a month of use, I noticed the raspy VFO tuning noise only on 10m, in
quiet band conditions.  I couldn't hear it anywhere else.

	I later received the internal ATU, battery charger  and the filter
module options and installed these all together in one session.

	 

	After adding these modules, I have noticable tuning noise on all
bands 17m and above.  It is reduced but not eliminated by the VFO NR
menu setting.

	On 20m, I can hear the artefact, but it is less noticable and has a
different quality:  softer and more like a pulsing shift in amplitude
of the background band noise as the VFO is turned.

	 

	None of this stops me enjoying my KX3, but for some reason, the
artefact became noticable on my KX3 only after installation of my
options.

	This is a "cosmetic" issue, without any functional impairment, but
it's un-attractive and I'm hoping a fix might be found some day.

	 

	73,

	John
