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.
Richard
