20M noise on transmitt


 

I am working portable at a relativizes house and found 20m has a digital noise on transmit. This is only occurring only on 20m and since I have nothing to test with have any of you seen this issue. My setup is the FT-857 a buddipole vertical and 50ft coax. My power supply is a powerwrx switching supply I have used many times.

Any Ideas would help.

Thank you,
Tim KM4ESU

Wild guess says try different outlet. ?Poor Grounding at outlet..
Move power supply away from radio, ? Reseat microphone RJ45...

Try turning Breakers off in the house to see what is generating the noise.
