where is the spectrum?

[ozner]

Hi! I'm new to the gqrx world.

I am running gqrx - 2.5.2-3 on mac el capitan. It works but I can see only the waterfalls not the spectrum. Probably I am missing some setting. Where is the switch to make the spectrum appear??

thank you!

The spectrum is just above the waterfall ;-)

Jokes aside, if you don't see anything there it is probably because
you need to move the vertical range and/or offset. It depends a lot on
what hardware you use, which gain settings and whether you have an
antenna connected or not.

Look under FFT settings.

PS:; the latest version is 2.5.3.

Problem solved! I've just clicked on the cursor "ref.level" (or "db range") without sliding it (at least as far as i remember) and the spectrum appeared.

At any rate, thanks for your prompt reply!

P.S. I confirm the spectrum is above the waterfalls;-)

Hi Alexandru and Ozner,

I have the same problem when using rtl-sdr and gqrx-2.5.3-57.
I went to FFT Settings and touched on Averaging, then the spectrum appeared. Weird!

Before that I got below warning when open gqrx or load a config file.
"Gqrx has detected problem with current configuration. Loading the configuration will crash...."

Is it the reason? What options do you suggest for rtl-sdr?

Did you have this behavior from the very beginning or did it come
after you were using gqrx for a while?
I thinki it is a bug but I have not yet been able to reproduce it locally.

I don't think so.
