New RTL_POWER Based Wideband RTL-SDR Scanner GUI

Rtl_power is a command line program that can do a very wideband frequency scan by quickly tuning through 2 MHz chunks of bandwidth and recording radio power values.

Now a new GUI frontend for Windows rtl_power called rtl panorama has been released which simplifies the use of the command line tool. To use it download rtlpan.exe from the sourceforge page and then copy the rtlsdr.dll, libusb-1.0.dll and rtl_power.exe files from the official Osmocom librtlsdr download to the same directory as rtlpan.exe.

You can hover over each of the controls to see a tool tip explaining which each button does.

Recently a similar rtl_power GUI was released and shown in this post. There is also the more featured python based RTLSDR Scanner that is not based on rtl_power which does a similar job. However, the rtl_power based GUIs appear to be much faster at scanning.

i got the same error, but eventually the file was created and it run without problems.

I followed the instructions above to install RTL Panorama and wen I start the scan I get the following error message. “Cannot open file “C;\users\Douglas P. Besemer\Desktop\rtl-sdr dongle panarrama\scan.csv”. The system cannot find the file specified.” I am running Windows 10 64 bit version and have selected the 32 bit version of this program to install. There was no instruction to install a scan.csv file.


This behaviour is because rtl_power used by RTLpan could not create scan.csv file in x64 system. No data input present, so nothing to draw. In Windows x64 dongle has two indexes: 0 and 1. RTL panorama exe file hard coded for index 0 device, whereas your receiver is device number 1. Try alternative RTLsdr_scanner in connection with rtl_tcp -d 1 (‘rtl_tcp=’).
