Fix input frequency in khz
Is it possible (is there a setting) to set the default input frequency in kHz instead of MHz?
Entering
the frequency returns in MHz
Not a big issue, anyway 😊

Re: Feature request OpenWebRX+
Perhaps, in the meantime, and getting back to your original question, if anyone wants to alter the height of their spectrum display you can do so simply by *editing .../htdocs/css/openwebrx.css
Look for a line that begins ".openwebrx-spectrum-container" (line #2069 in the file I just viewed) and change the "max-height:" directive in the block below from 50px to your preference - for example 100px.
Do the same for the following block beginning ".openwebrx-spectrum-container.expanded"
This should be all that's needed, you may need to refresh your session and/or restart for the result to be observed.
Note: If you're at all uncertain you would be advised to back up your installation before making any changes.
That said it's an easy change and I'd encourage people to experiment and learn more about their systems. Who knows, one day you may be able to contribute some code back to further improve OpenWebRX.
*A good editor for many Linux distributions is 'nano'.

Re: Feature request OpenWebRX+
Looks good, thank you for your contribution.
I hope at some point your work can get rolled into a future release of OWR.

Following a little sunshine... :
White peak hold line could be any colour, incl the gradient applied to the spectral display, same with the labels.
Re: Feature request OpenWebRX+
Martin,
I downloaded Marat's recent work and had a look re your request. It turns out he's changed things quite a lot since I originally implemented the spectrum display, so although I still think you should have a go I also took pity on you ;)
Per the images below I've implemented a 'peak hold' line as well as reintroducing the spectral colour that I used to have in my version. The latter is simply personal preference, or vanity if you prefer, as it happens I quite like Marat's single colour display but while I was messing around with things I thought why not?
Did additionally consider adding the relative dbFS lines I had but was running out of [solar] battery and had spent quite enough time trying to find a working SDR unit and set up a machine etc etc (sadly my Mirics-based device appears to have died, so had to find an old 'TV' RTL device instead) therefore this is what you've got.
For the present the peak hold line will remain until the spectrum display is toggled off, at which point it's cleared. It could also be easily set to decay over a long period if that was preferable. If it's of interest I can tell you what to alter/add in the requisite file, or maybe just email said file to you....

Re: OpenWebRx, Airspy r2, Raspberry Pi 4
I can confirm that. A NUC is a very good choice for OWRX(+).
I am also running an Intel NUC5i3 with an RSPdx, an AirSpy HF+, and an RTL-SDR V4.
I have taken my Raspberry Pi out of service.

Re: OpenWebRx, Airspy r2, Raspberry Pi 4
I have recently switched to using an Intel NUC i5.
When compared to the price of a new R-Pi 5, there was no contest and the performance is much better. The NUC is around twice the physical size of a cased R-Pi and about half the price of a R-Pi5 4Gb.
A good used NUC i5 (or i3) can be had on the famous auction site for not too much money.
If you shop wisely, you can get one with 4 or 8Gb RAM and a 120Gb SSD, most are without a PSU, but a suitable laptop PSU will work fine (they will run from 12v - 19v).
I struck lucky and got a 'barebones' NUC5i5 for under £20 (20GBP) delivered as I had a suitable 4Gb stick of RAM, 120Gb SSD and PSU from a dead laptop - winner!

Re: Feature request OpenWebRX+
Yes, OWR uses dBFS, it has to be this way because it can use different receiver hardware, each with different gain settings.
It could be possible to calibrate using a signal generator, but most admins don't have access to such things.
The Kiwi uses standard hardware, so the software can be roughly calibrated using pre-determined average values, however these do vary from batch to batch, and there is an offste value that can be applied by the admin, if they have a suitable calibration source available.

Martin

Yes, it was me to mention the FW-deviation issue.
Yet, I am still convinced that OWRX still works with dB_FS and does not offer and dBm-calibrated reference.
The latter is found with Kiwi and web-888.
But I can live with that - as well with the unavailable GPS-reference.
openwebrx is and remains attractive - thanks to Jakob and Marat!
