Thanks for all of the responses and the great information, everyone. The
radio sounds worderful, I just wasn't sure why I was seeing what I was
seeing. I really enjoy the radio, and I really enjoy this forum.
Thanks again

Thanks for the clarification, Bob. Now I understand why I'm seeing the
sine: In SAM mode the pll in the SAM detector locks "perfectly" to the
carrier, but the Display (e.g. SCOPE) uses "pre-detection" data, and so we
see the carrier (i.e. pre-lock) in the Display.

Predection signal (the real component), post agc is all we display on
the scope. We can do more, and we will eventually but I want you to
understand why we have not just "slapped it together and thrown it
out". All of the signals post detection have agc applied and some
detectors need real, some need IQ, etc. etc. This makes scaling of the
audio for spectral display a bit interesting to say the least. It is a
bit more of a question of how to arrange all of these different
presentations of post detection data in a coherent fashion and the time
needed to document how all of the different modes should work, etc..
In SAM, the signal is "perfectly" tuned due to the phase locked loop.
On the suggestions that we should all independent selection of sidebands
in SAM, it really should be even richer than that. Hopefully we can
revisit this soon but not now.
The only things on my agenda are getting 1.6.0 out of my life forever
;-) and getting the impulse generator into operation.
