Agree with this. Please change to dB.
[Not sure what PBNP is.
That is "passband noise power". It is a real-time estimate of passband noise power based on the power measured in the panadapter RBW (resolution bandwidth) and as displayed by the noise line. This power is scaled/normalized to a 1Hz bandwidth and shown as NPSD--noise power spectral density. That noise power is again scaled/normalized to the passband bandwidth to obtain PBNP.
While PNBP is technically only an estimate, it's pretty accurate. You can adjust it further by going to a quiet part of the band, switching the S-meter to show dBm (Settings > Display > General), then going to Settings > General > Options > Options-2 and adjusting Noise Floor Shift. It shouldn't be more than a couple of dB off.
With PNBP being estimated, that gets you a real-time PBSNR: passband signal-to-noise ratio. SNR is, arguably, a much more useful metric when judging signal power and quality. Not the norm in the CW/phone realm yet, but very familiar to the digi mode folks.
If your PBSNR reading is not updating often enough for you, its update rate, and the update rate of all the rest of the values on the InfoBar (the strip just below the spectral display) is controlled by Setup > Display > General: Refresh Rates CPU Meter. I have mine set to 250ms and that seems to work quite well. If you want to report SNR in S-units, just take the PBSNR value and divide by 6 in your head
These new metrics are wonderful additions, thank you Richie!
