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

[Dave Lankshear]

I built mine, complete with auto ATU and roofing filters, so at this stage
I'd have to take the rig apart to see if the peripherals contribute to the
tuning hash, but even with noise reduction on, tuning makes quite a
swooshing noise and gets louder as the tuning rate is increased.  When my K3
still emitted some tuning hash after the mods to suppress it, I thought I
must be quite sensitive to it, but the KX3 is much louder.  I hadn't said
anything before because of experience with my K3 but as it's been raised, I
thought I'd "come out" about it.  My K3 is a little noisy, but I'd still
expect to hear signals from workable stations as I tune through, however,
the KX3 could readily miss ones that are workable above the band noise level
unless I was tuning slowly.
