[Elecraft] K3 VFO tuning hash

[Dave Van Wallaghen]

John, I just noticed the same thing on 10m the other day. If I used the finger dimple, I could hear it. But if I used the outer rubber ring with 1 or more fingers it would not be nearly as noticable.

I was operating portable in my yard with around 150' of extension cord to power my Gamma PS. 

I thought about searching the archives for something about this. Funny you should mention it.

Subject: [Elecraft] K3 VFO tuning hash


Now that 6 and 10 meters have been open to Europe and Africa, I frequent
these bands for the first time in the six months of owning a factory built K3 radio.

What I've discovered and reported to factory tech support is a very noticable hash noise
while in the receive mode with any bandwidth centered around 28.000 MHz to 28.050 MHz.  And, it is also
present while tuning RIT.  It sounds like synthesizer switching noise and its repetition rate increses when the VFO is set to fine
tuning. I do not hear it on any other band.  I also don't hear it over the entire 10 meter band, just the region as stated.  

Is this in other K3s or is there something going on that needs attention in only my radio?  I called factory tech support over a week ago.  Since they have not come up with an answer it seemed time to open it up to a wider group of users.

Thanks

73,

John,  W1QS
