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.

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!
