I've noticed a disturbing tendency to quote the thermal noise contribution to phase noise as -174dBm/Hz instead of the corrent value of -177dBm/Hz as verified by measurement by NIST:
http://tf.nist.gov/phase/noisemeas.html

This error occurs in papers from Spectrum Microwave, Wenzel Associates and others. Blindly propagating the results quoted in the early literature isnt particularly helpful given that the definition of SSB phase noise has changed in the intervening decades.
