Try running a spectrogram. The hard tone (ie., carrier) is just a
thin straight line on a spectrogram and can be ignored. Tiny faint
pings are easily visually separated from the carrier and also easy to
count. You don't even need a direct radio > PC audio connection if
you have a microphone (like on a laptop).... just put the receiver
speaker near the mic. Not as good as a direct connection, but dead
easy to try.
Set to scroll slowly at 1 pixel/2 seconds (over an hour per
screenful), I can easily detect residual carrier, airplanes and pings
that are completely inaudible.
Spectrum Lab is a very popular choice for this and is free.

Put the carrier at about 1KHz and set the screen for +/- maybe
200-400 Hz and you will be amazed what it will reveal.
