This weekend I listened again for LO-19. Years ago, when the CW beacon went silent, I could always hear a very weak continuos carrier (actually, first saw it using audio FFT software). Yesterday (12/9/12) on a high 50-ish degree elevation pass, it was there. It's right on frequency, right on time with AOS/LOS, the Doppler correction from SatPC32 is right on target. The bird was in daylight, but I expect its batteries are still good so I bet you can hear it in eclipse as well.
Thanks to Mark WA8SME for confirming what I was hearing; he heard it this weekend, too.
You might have fun listening for it, as a weak signal source. If you can hear LO-19's carrier, your system is pretty up to snuff. Or, use some audio spectrum software and you can "see" the carrier even if you can't hear it on your speaker.
