Here's the time domain scope result using sdr-iq2 and eprobe1.
Presumably the Spectrum Lab settings are the same as the earlier image
using sdr-iq1 and eprobe2, but the results are quite different. This
image averages away the drooping oscillations, leaving only the first
peak and the last minima. The timing is also shifted, despite using the
same tSync value. Perhaps the eprobe2 SNR is too weak to trigger the
same way eprobe1 does. It will be interesting to see how the displays
look after sunset when the SNR should be much improved. At about 750
miles it's nice to see the signal is making it here at all during daylight.
