Re: [Elecraft] KX3 - broadcast band interference ??

2016-12-21 Thread yo8sep 
There is an AM broadcast station at 40miles from me,  but the signal I got
was on a foreign language,  maybe somewhere Middle East...
And it was all over the band,  even on upper bands,  15/10. Turning off Pre
or turning on RX SHIFT 8KHZ, seems to solve/hide the problem.  But that is
not really a solution,  especially when using NAP3 and CW skimmer.

Are you close to any AM broadcast stations?

The strange thing was that was heard even when tuning to different
frequencies.
PRE was on, antenna was yagi 3 elements on 20m, at 12m height.

I've made a short video, sorry for the poor quality.

If I changed the RX SHIFT settings to 8KHz, I still could see that signal on

panadapter (NAP3) but audio was shifted to 8kHz.

What could cause that problem/interference ?

[Elecraft] KX3 - broadcast band interference ??

2016-12-21 Thread yo8sep 
A few days ago I've noticed something strange at my KX3.
If was around dusk and I was on 20m band, USB trying to listen for a very
low signal station and got something that looks like an AM brodcasting , but
not in a language that I can understand.
The strange thing was that was heard even when tuning to different
frequencies.
PRE was on, antenna was yagi 3 elements on 20m, at 12m height.

I've made a short video, sorry for the poor quality.

If I changed the RX SHIFT settings to 8KHz, I still could see that signal on
panadapter (NAP3) but audio was shifted to 8kHz.
