Bigger range scan.

[Xiaomi Takahara]

Hi there,

How Can I scan bigger frequency range spectrum like it is on this group thumbnail? When I zoom out with mouse scroll, it makes bigger up tp about 24 Mhz (range between 86-110 Mzh) but it's still monitored only about 2 Mhz and neighborhood frequency are black screen. I'm using RTL-SDR dongle with its antenna. Thanks for answer and links.

Hi Xiaomi,

The RTL-SDR dongles have a maximum bandwidth of 2.4 MHz. This is dictated by the sampling rate they support. To receive a wider bandwidth you will need to use a better SDR, e.g. Airspy and others.
