I'm hearing something occasionally on 1500 that I'd describe as a
short-duration data-tone type "screech" over top of a higher pitch warble.
The "screech" shows up as a narrow line on the Perseus display on USB only
while the warble is audible on both USB and LSB.

I thought it was local QRM but wonder if this is what others are hearing?
