KX3

HI All

I have a KX3, #262.

I have an issue and I wonder if others have found the same, It's in relation
to the ENCODER.

There is a distinct noise as you turn the tuning knob and it is seems to be
frequency sensitive.

On the Bands from 1.8 to 10MHz there is No noise.

On the Bands from 14 to 21MHz there is Light " rasping " noise.

On the Bands 24MHz and 28MHz the noise Doubles to Medium.

On the 50MHZ the rasping noise is double that on 28MHz and is Very annoying.

The encoder I have in my KX3 is the one which is not soldered to the PC
Board.

Anyone else have these symptoms?

David,

VK4DH

Re: KX3

Try enabling VFO NR in the menu. You'll have to unlock to do this.

Dial up the VFO NR menu entry, then hold the KHZ key down until the
lock icon disappears. Use VFO to change the setting from OFF to ON.
Exit the menu.

Yes, everyone has these symptoms. You can help the situation some by turning on the VFO NR in the menu. You have to unlock the menu by holding the rate button for 3 seconds until it says "Unlocked". This has to be done by band.

Hi David,

I justed received my KX-3 a few days ago.

I also noticed here the same noice problem with the encoder.
The noice during VFO tuning is rather heavy on 18, 24 & 28 MHz, on the lower bands no problem.

Anyway very nice radio...
