I have a new source of QRM that is audible on 12 meters only. It
appears to cover  24 to 25MHZ. The audio frequency of the signal
changes as I go lower in frequency. Both of the following recordings
were made with a 6kHz filter in AM mode.

At 24.890MHz it sounds like this:

At 24.820MHz it sounds like this:

The signal has QSB and, my ham neighbor and I both locate it as coming
from due west. Is anybody else hearing this signal? Any ideas as to
what the source might be? Thanks for any ideas.
