RTL_SDR_Wide_Spectrum_Analyzer

Hi!
This is my page for RTL_SDR_Wide_Spectrum_Analyzer software for RTL2853U dongle.
Prerequisites:
-rtl_sdr utilities (http://sdr.osmocom.org/trac/wiki/rtl-sdr)  installed such for gqrx program
Software is written  in "basic for gambas" language.
In this page there are packages for Ubuntu   and for others linux versions.
Before testing this program, i suggest:

• install package "rtl-sdr" (in ubuntu sudo apt install rtl-sdr) 
• to test functional of hardware/software with other rtl_sdr software like gqrx
• to test presence of rtl_power  utility (present only in recent version of rtl_sdr utility.
  (from terminal, you can type rtl_poer to verify....)
