RSPduo spectrum expanded #1782

sdrtrunk 0.6.0 release macOS 10.15 RSPduo

I observe that RSPduo's spectrum is expanded compared to hackRF and rtl-sdr. It can be seen that adjacent P25p1 channels overlap each other. On hackRF the channels are clearly visible.

Or here is the NBFM channel 12.5 kHz. The spectrum goes beyond.

I installed Nightly available the version now and nothing has changed in the spectrum. SDRPLAY API 3.15

I can't fix this.

Look. This screenshot is made today. The version of the program is the last vnightly. I have the impression that the width of the spectrum depends on the signal level. Very weak signals contain the width of the spectrum. In the screenshot DMR mode
