There are four candidate objects in Celestrak's TLE-NEW file

Their North American passes have already occurred for today. KM0MMM,
AA5PK, and others have reported hearing the beacons. A video posted on
Twitter by KM0MMM of his SDR seems to show signals within the
transponder passband as well.

I will be listening on my next pass in Washington DC around 09:00 UTC
tomorrow morning.

73,

Paul, N8HM
