Tom,
A while back I experimented a little with using WWV's 20 Mhz signal similar to what we're doing with Kickapoo, but the results were negative, and of course you would need many test points to identify a correlation.
In theory, higher HF bands are ideal for scatter. Below 15m, wavelength, QRM, and an almost constant level of some kind of ionospheric propagation would (to me), preclude it's use.
Within a couple of years, we're going to have to find a replacement for Kickapoo. They are working an active track, X-band pulsed radar replacement, so it's days are numbered.

I am not aware of any HF radio ( high frequency or decametric ) direct
emission monitoring of meteors or papers on the subject.
On Feb 27 2051:52 MST ( Feb 28, 2012 0351:52 UTC) a nice fireball
passed through my 21 MHz yagi antenna recently and I checked to see if
there might be any detectable emission but cannot discern any.
