RFI Problem related by routing audio through K3 (uBitx)?

Björn Pasteuning
 

Hi all,

I have just received my uBitx,

From start I have noticed RFI problems while TX'ing and coming audio from the speakers.

I have shorted all wireing to a minimum.

I looked at the schematic, and see audio is routed through relais K3.
Although audio is switched "loose" while in TX, could this be a culprit?

Anyone else experienced this problem?
