Spectrum not showing full bandwidth
Posted: Thu Oct 29, 2020 3:57 pm
Hi All
Now that my start/stop problem is solved (thanks excellent Forum!) I have another issue to bother you with.
Same Pluto, but older lower performance PC.
The issue is a spectrum/waterfall that has lower bandwidth than expected. As far as I can see all settings are the same as work on my higher performance machine, and I have changed away from Manual gain. Attached are screenshot and log file. [Both were captured when RX gain was set to Manual, but changing that does not affect the issue with this PC.]
I have tried all 3 available USB ports with same result.
When the radio starts, briefly the spectrum is wider but then settles to that shown in the screenshot. Could this be just very poor USB performance?
I haven't tried powering Pluto externally yet, btw.
