220 07-Aug 0:08:30 Start 7 40 60 180 x10 100 2048 Region of storms over SC Cheyenne Co.
1:12:10 Stop Switching to RF-thresholded interferometer (though still distant)
221 08-Aug 0:09:40 Start 7 20 30 600 x10 100 2048 Output of calibrator is connected to Ch. 3 (instead of SA) and is terminated in 50 Ohms
0:19:00 Stop Should have sufficient data for calibration of Gain 7
0:20:00 Start 7 20 30 700 x10 1000 2048 Almost same as previous, except for longer time constant
0:27:00 Stop More than enough data for calibration :-)
0:30:00 Start 6 20 30 200 x10 100 2048 Gain 6 calibration
0:43:00 Stop
0:45:00 Start 5 20 30 100 x10 100 2048 Gain 5, at 10x, calibration
0:54:50 Stop
0:57:00 Start 5 20 30 700 x100 100 2048 Gain 5, at 100x, calibration
1:06:50 Stop
1:10:00 Start 4 20 30 500 x100 100 2048 Gain 4 calibration
1:27:00 Stop
1:28:10 Start 3 20 30 500 x100 100 2048 Gain 3 calibration
1:48:00 Stop
5:21:00 Start N/A 50 200 1000 N/A N/A 2048 Ch. 3: Output of calibrator Ch. 4: Output of pulse generator, which is connected to ground plane and calibrator plate above sensor.
5:21:48 Stop Collected over 23 MB of data (more than enough)
5:49:00 Start N/A 50 200 1000 N/A N/A 2048 Same as before, except pulse generator signal is different (see notes)
5:49:45 Stop
223 10-Aug 3:11:00 Start 7 30 90 200 x10 100 2048 Looking for sprite ELF from broad stratiform region >100 km to SE
6:00:00 Stop Stratiform region is falling apart
224 11-Aug 4:21:00 Start 7 30 90 200 x10 100 2048 Storm S. of Burlington. Large stratiform region further S. at >150 km
4:59:20-35 ITFR XMR is on (testing antenna #6 - still bad)
5:50:(35-55) Stop/Start 6 100 Discharges going off scale more frequently, so reduced gain
6:40:00 Stop Storms to W have decayed considerably in past hour
