[Elecraft] Kx3 rfi when power set to 0watt

[Peter Eijlander (PA0PJE)]

Hi Eben,

Welcome to "Radio-land"

If that is normal is not for me to decide but...

I actually measured the power level of my KX3 in CW with 0.0 watt as set 
level.

It varies from band to band. On 50 MHz I found -18 dBm and on the HF 
bands between -20 and -30 dBm.

On 14 MHz I found -23 dBm as carrier level and the noise over the range 
from 3 to 18 MHz -50 dBm, dropping rapidly to -80 dBm on 20 MHz and above.

-23 dBm = 0.005 mW or in "S-units" S9+50 dB. Enough to drive a sensitive 
receiver nuts in close proximity. A good dummmy load to terminate the 
KX3 is always a good idea when "dry-land swimming" the radio.

73,
Peter - PA0PJE
