A tiny Mac OS application for monitoring power levels of a given range of radio spectrum. It is dependent upon the command-line application rtl_power developed by Kyle Keen & bundled with rtl_sdr by Osmocom.
RTL Watch by design keeps a very small and undistracting presence. The program's base interface is contained within the user Menu (aka Status) Bar, no Dock icon is present and the only Window is a brief configuration dialog.
Power levels are displayed through sparklines, there are currently two choices of display: Unicode blocks ( eg ▆▃▆▃ ) or Braille characters ( eg ⣿⣶⣿⣶ ). All information is displayed through these Unicode character sets.
28/08/2016 - Added detection for missing rtl_sdr packages.
Made for Mac OS.
