Perhaps this deserves some attention from folks in this N.G.; there
are a number of online receivers to use in chasing this signal.
I went to http://adamsj.dynalias.org/RCSweb/ in North Carolina
and at about 2045 UTC the signal on 4800 kHz was 20/S9.
I recorded 30 seconds of the audio using these settings:

mode: USB, filter: 2100 Hz, AGC: slow

Listen he http://www.cybertheque.org/ham/audio/4800chirp1.mp3

I am not hearing it here in No. MN.

For other readers, please take the time to use some of the online
receivers and check for it in other locations.

Perhaps also use other modes and filter settings and perhaps
submit it to spectral analysis.

Report here ;-)
