# Looking Glass
This App Provides a view of the spectrum over a set range of frequencies. The waterfall display is updated with each full scan. It should be noted that for wide scan frequency ranges the scanning time is very long and the display can look like it has frozen. The key is to keep the band scanned as small as possible. While the HackRF is in RF terms a poor receiver in terms of sensitivity, the Portapack/ HackRF can provide a very useful to scan for local Radio signals Using the appropriate antenna. The Looking glass is an excellent tool to visualise the spectrum and if set to a narrow scanning range can see the on/off patterns of the radio transmission.
The frequency ranges are held in the SD card >LOOKINGGLASS>PRESETS.TXT. It should be noted that the size of the frequencies should be keep small to limit the memory use.
