Investigate possible intermittent oscillation in raw samples #37

Open loxodes opened 7 years ago

loxodes commented 7 years ago

Sometimes the raw baseband samples show a high power signal that may start partway into an integration period and continue to the end.

When it happens, it is visible to some extent on all working antennas on the main array. This could be oscillation, or it could be another transmitter. We should check data from the back array during an interval with possible oscillation to differentiate this against a signal from another transmitter.

(Or take a close look at the RF samples and look for modulation?)

Bill suggested looking at the raw sample dump of from the clear frequency search at times with vertical streaks on the RTI plot.
