216 03-Aug 4:25:20 Start 7 35 1 x10 100 N/A Line of storms to north.
4:39:20 Metallic push rod along-side V.B. was removed (see notes)
4:49:(12-25) Fixed 4+5 signal. Was compressed along one direction
4:56:(00-02) 6 Selected gain setting twice (2 secs apart) to insure proper setting
5:14:(00-01) 5 Selected gain setting twice again
5:23:00 4
5:23:08 x100
5:31:13 3 Discharge saturated SA at approximately 5:31:00 UT
5:34:15 Fixed 4+5 Cosine again! @#! (was compressed again)
5:41:25 2 Another (see notes) large delta-E offscale (+ and -!) prior to gain setting
5:53:20 3 Storm moving off to SE
6:03:00 4
6:12:30 5 (still x100 on the FA output)
6:35:(40-42) 4 Selected twice. Cells to ~N-NW are coming closer.
6:41:35 3 Field change offscale prior to change-of-gain (see notes)
6:48:29 2
7:19:20 3 Storm moving off to SSE
7:24:10 4
7:50:00 3 Activity to ~NNW is getting closer
7:58:53 2 Delta-E offscale several seconds earlier (see notes)
8:15:00 3 Acitivity is diminishing and moving off
8:23:50 4 Flash rate has really slowed and is more distant
8:38:50 5 Lightning activity appears to have died
8:50:00 Stop
218 05-Aug 2:55:30 Start 7 35 1 x10 100 N/A Cluster of storms over ~northern half of Yuma Co. and northward
3:40:30 6 delta-E's were starting to go off-scale
4:14:00 5
4:17:35 4 Field change offscale prior to change-of-gain (see notes)
4:18:(11-15) x100
4:58:00 5
4:58:03 x10
5:09:30 7 Receeding storm has dissipated. Delta-Es are small.
6:34:35 6 Large +delta-E more than a minute earlier (see notes)
6:53:33 Fixed Cos 4+5: was compressed (for how long???)
7:02:00 Stop
219 06-Aug 0:51:10 Start 7 34 1 x10 100 N/A Cluster of storms in W. Kit Carson Co.
1:03:40 6 Large -delta-E prior to change-of-gain (see notes)
1:10:50 7 Over-sensitized SA in order to look for onset of discharges (power outage: no AC!)
1:11:15 30 RF-threshold is now within noise-level in order to maximize data collected.
1:14:45 6 Forced to desensitize SA after gust front hit (airborn dust, etc..)
1:15:10 Stop/Start 31 Raised threshold since trigger rate was so high that buffer occassionally filled.
1:16:10 5 SA was eratic because of high winds
1:16:15 Stop/Start 34 Lowered trigger rate.
1:17:57 Stop UPS battery is low on power: forcing a complete shut down.
3:01:20 Start 2 34 1 x10 100 N/A Powering-up for possible overhead large discharges and close +CGs
3:01:(42-45) x100 Forgot to reconnect at x100 before start of recording
3:10:55 Stop/Start 36 Raise threshold to decrease likelihood that a long duration discharge will fill buffer
3:25:(30-40) Reconnected V.B. cables to front of V.B. rack. Oops!!
3:31:25 5 No field changes seen for a while. +CG-producing region decayed earlier.
3:31:(30-35) x10
3:45:45 7 Lightning activity is distant.
4:05:00 Stop All lightning is outside of useful interferometer range (and in 2D range of LMA)
220 07-Aug 1:12:30 Start 7 40 1 x10 100 N/A Region of storms to S and SW at >60 km range.
1:25:30 Stop Need to clean SA
1:34:00 Start 6 35 1 x10 100 N/A SA was cleaned, but static displacement is offscale at gain of 7
2:00:50 Stop SA way offscale (no FA?) and activity is moving off
3:25:00 Start 7 35 1 x10 100 N/A A couple of significant upward field changes seen in previous 2 minutes.
4:06:00 Stop No field changes seen for a while.
22:33:10 Start 7 30 1 x10 100 N/A Cumulus congestus developing to N through NE
23:34:00 Stop About ready to perform calibration (using calibrator)...
221 08-Aug 1:55:30 Start 7 33 1 x10 100 N/A Storm to West (and possibly NNE too)
2:09:10 Stop/Start 34 Trigger rate was high (DSP LED bright red). Distant interference?
2:12:20 Stop/Start 35 Trigger rate is still high
3:03:00 Stop Storm(s) to West fell apart earlier...
19:39:20 Start 7 32 1 x10 100 N/A Convection to SSW with low tops and high bases. Static heard on AM radio.
19:53:07 "Stop" DSPs crashed (first time in a couple weeks)
23:42:20 Start 7 31 1 x10 100 N/A Convection to SE is growing
222 09-Aug 0:27:30 Stop/Start 32 Trigger rate too high. Files were not closing due to lack of a sufficient pause.
0:29:10 Stop/Start 34 Trigger rate still too high.
0:41:00 Stop/Start 35 Needed to close out another set of files (and raise threshold)
1:06:00 Stop Convection to SE died earlier and no new activity
223 10-Aug 00:01:40 Start 7 35 1 x10 100 N/A Large stratiform reflectivity region at >80 km range to SE. May produce +CGs.
3:10:40 Stop Activity is beyond useful range of VB (has been for a while). Goto sferics...
225 12-Aug 0:52:30 Start 6 33 1 x10 100 N/A Convection to W (active?). Gain 6 used since high winds prevent Gain 7.
1:27:00 Stop/Start 35 Lowered trigger rate.
1:28:02 7 Winds and airborne dust diminishing a bit (but still significant)
3:51:00 Stop Closest storm is near Lamar, CO, far to the south
4:26:20 Start 7 35 1 x10 100 N/A Line of storms near Wallace/Logan Co. line (south of Goodland, KS)
4:36:(10-13) ITFR XMR on briefly: checking antenna 6 (good)
6:17:00 Stop All activity appears to be distant
20:14:10 Start 7 34 1 x10 100 N/A E-W line of convection building to S. over central Cheyenne Co.
21:33:30 ITFR XMR: checking antenna 6 (good)
22:25 Significant ITFR (from where?)
22:26:10 35 Raised threshold in order to lower trigger rate (ITFR present too?)
22:37 ITFR has returned? Trigger rate very high.
226 13-Aug 0:03:20 6 Storms are slowly getting closer
0:57:10 5 Storm to S is getting closer, but may be decaying too (low flash rate)
1:13:00 36 Trigger rate was too high. Filling up buffer. ITFR LED lit briefly too.
1:22:50 37 Trigger rate too high. ITFR?
1:32:20 "Stop" DSPs crashed
1:35:35 Start 5 37 1 x10 100 N/A Recovery from DSP crash
2:03:10 38 Attempt to lower trigger rate. Can be very high & steady at times. ITFR?
2:13:30 40 High trigger rate.
3:09:00 44 Lowered trigger rate, which was very high.
3:27:15 7 Line of storms continues to decay from S end. +CGs are now up in Nebraska
4:40:00 Stop All activity appears to be distant
