True, not bad. One surprise, though – what’s that notch around 1420.5?
It definitely has an “averaged” look to it – much like what you’d
expect
from time smoothing and not frequency necessarily. One thing that
low-level
heuristic grass might give you is a feeling that the relatively flat
segments are alive at least, sort of like comfort noise during vocoder
silence. If that matters.

The Fc is 1420.4058e6Hz, and since it’s a direct-conversion receiver,
there’s always a little spectral artifact near DC.

OK, so I decided to use the averaging method, rather than
the maximum
method. It produces reasonably good looking plots:

Can you post a link to what you saw by the maximum method ?
This is averaged both in frequency, and time. Each bin is smoothed
with an integrator–needed for doing astronomical work, like
showing the HI line, etc. The HI line is strong in relative terms,
but in absolute terms, it’s terribly weak
