Have you looked carefully? I have to zoom in on the bandwidth in order to see
it. Somebody else called it a birdie.
My unit came from R&L. I'm reasonably sure it's genuine.
If I look at 10 MHz center and 25 or 100 k span, there is a faint something
down in the noise. Most of the time, the marker that automagically ends up on
top of the highest peak is in the middle. At a quick glance, there is nothing
there. If I look carefully, there is usually a small bump about 3 kHz wide.
It's easier to see at 25 kHz since it's wider. It's faintly visible on a
waterfall.
That's with the antenna terminated or when I wander down the street. There is
a similar thing at 50 MHz.
