Well, monitoring all night on 55.250 AM, I got zero meteors on the 
spectrogram.  At least nothing that looked like a meteor..... ie., 
short duration.  The only signal I detected was a semi-continuous 
"tone" spread out over 20-50 Hz and centered on 1200 Hz and a 
secondary one (harmonic?) on 2400 Hz.  It looked like a steady 
carrier would look on USB if it was reflected from the auroral 
curtain.  I suspect it is local, but it does fade in and out randomly 
like it is affected by propagation so it might be a distant signal of 
some sort.

When I switched back to 55.249 USB, meteors were plentiful (average 
of about 2/minute).

So the verdict here at least is use USB, LSB or CW.
