Since this was a good opportunity, I went a little deeper in the recorded data than normal and extracted event metrics.
The radar scatter system here at the house records scatter spectrum from the VHF USAF Space Radar beam from Lake Kickapoo, Texas.  The USB audio is fed into a creative labs EMU-0202 USB sound box where it is sampled and FFT'ed by Speclab for a spectral waterfall plot.
Waterfall spectrum images spanning two minutes are saved automatically at that rate throughout the day.
I went through all images this morning, manually recording the times of meteor hits.
The data is a bit noisy towards the end of the local day because a line of thunderstorms pass over the radar transmitter, and continue through central Oklahoma.  This adds a lot of radar scatter hits from lightning, so it's harder to discern under-dense events from lightning scatters.  But you can clearly see the diurnal cycle in meteor events with the spike at 3-4 Hrs.
If any of you are interested, I'll send the excel spreadsheet with the exact times.  But for here, the resulting numbers are pasted below.
Clear skies,
