Kevin Reid, AG6YO has a description of I & Q as part of his
visual introduction to SDR and DSP at
<http://visual-dsp.switchb.org/>. He will be presenting the same
material at the March 11 meeting of the West Valley Amateur
Radio Association (www.wvara.org) in San Jose, California.
Anyone interested is welcome to attend. (See the web site for details.)

I am having trouble with I/Q modulation. 1) Do the I and Q
components have a frequency, or are they just amplitudes. I
would suspect the former.
2) How is the change in the phase difference for the I and Q
symbols, compared to the reference frequency (carrier?)
determined? I believe I understand the math, but I don’t
believe this is a Faraday statement that what you can see/sense
can correspond to a physical model, but beyond that math has to do.
Sorry if the is too basic, but I am really trying to understand my KX3 and PX3.
