[Elecraft] spectrogram

John,

Sjpectrogram is a FFT (Fast Fourier Transform) spectrum analyzer program.  It's display is amplitude versus frequency.  What you need to display the "Christmas Tree" and CW waveforms is an  oscilloscope display.  In the case of the Christmas Tree, the oscilloscope is set up to display RF drive or audio on the horizontal axis and RF output on the vertical axis (the oscilloscope is in X-Y mode, with x=drive, Y=RF out).  For the cw envelope you use the oscilloscope in the conventional mode where the horizontal axis is time and the vertical axis is voltage.  So the short answer to your question is "NO".

>can Spectrogram also show the
>Christmas Tree effect for SSB? How about the rise and fall of the CW note?
>What about in receive mode. Can it also show these for the received station?
