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 _______________________________________________ UR RST IS ...

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 fiel

Jeff, I suspect that you mean modern day synthesisers rather than specifically DDS. Actually, the DDS itself has quite low phase noise, better than -130 dBc/Hz with Analog Devices chips, especially i
