Hi Stuart,

Yes, I know what you meant.  It is just that all the years I spent doing
standards and compliance engineering in the telecom industry have made me a
stickler for correct terminology in units of measure.

Per ITU and ISO standards, which have legal and regulatory binding force in
all member countries, "dBm" is more than a mere label - it is the legal
definition of dB with reference to an absolute power level of one milliwatt.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

Adam,
Although meters are "labeled" to say dBm, that MEANS dB re ONE MILLI WATT.

That is all I was saying, and just abbreviated it.
