Good morning Jose Alberto, Thanks for coming back. Yes, laptop power supply is noisy and have isolated that, along with printer, phone/broadband line etc., radio run from linear pwr supply. However, noise is picked up off dipole antenna. Now, solid white noise s5 on 14Mhz and less, up to S8 with pwr line noise on top, intermittently. Will have to borrow portable radio to trouble shoot. I wonder if it is PLC (power line communications)? What is your background noise on S meter and is it White Noise and/or usual powerline noise? Cheers.
New subject: Good morning. I’m back on the air after an absence of many months. However, at this QTH dreadful “White Noise” 1.8-14Mhz up to S6, 18Mhz=S2, 24Mhz=S3, others <S1/2. Bands virtually unusable! Is there anyone else who suffers from the same malaise?
Usually, i am disagree with who says “ROS is a virus” or “a NATO proyect that uses to Hams” or “must be illegal in USA” and others stupid things.
ROS users want a free trolls group. As Groucho Marx said, a child of five years would understand this.
