My noise floor is fuzzy. The bottom is -110, even when the display goes down
to -120. The fuzz is ~3 dB.
My 10 MHz birdie looks like it is
Hal, my 10 MHz birdie is at a level of about -95 dBm, which puts it a
little more than
10 db above the noise floor in 3 kHz BW.
I've found that the "spur removal" function sometimes works, but not
always, if I
change the IF frequency setting to 433.9 MHz. It's mostly bimodal behavior-
sometimes

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 I'm reasonably sure it's genuine.
If I look at 10 MHz center and 25 or 100 k span, there is

I use RG400 for most of my time nuts activities. When I switched from cheap
RG58 style coax to RG400 a number of strange issues seemed to go away for me.

You can get custom-made decent quality cables with double shielded coax
(either RG-316D or RG-142) from China (where else?) for pretty low
prices. I am sure the cable isn't mil-spec but I cut a piece open and
the shield coverage, which is the main thing I worry about at HF
frequencies, is

Yes. RG400 or RG316. Do NOT use RG58 or RG174. Both

There is no birdies on mine that I can see, even as I decrease the RBW. -

My tinySA arrived a few days ago. I'm happy.
It comes in a nice box with an antenna that extends to a foot, a USB charging
cable (mini, not micro) and a couple of cables.
It doesn't come with a manual. I haven't found a manual online. Their web
site is pretty good, but sometimes I like a
