Phase noise is generated by the rig's LO and exists as a more broad band low level signal. Issue is more significant with modern day DDS than with older analog-type VFO sources. Guys who operate field day can relate...
73/jeff/ac0c Don't you mean IMD from the radio/amp driven past ALC? CW is a binary signal and no one complains of its "phase noise" ..... Mike KC7NOA I had a ham, who is now SK, that lived 3 miles from me. He had two Kenwood TS-940s. The phase noise at my house was S9+20db when he was listening on 20 meters. It was there whenever the 940 was turned on. It was from about 11mHz to 18mHz. He could not hear it, figure that out. 73 Price W0RI _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
