Waterfall on WebSDR is not useful, because it

Description

Background: A waterfall display shows signal strength at different frequencies. It draws one line per sample, and scrolls these lines.

Background: sdr radio is a system that allows for the use of other people's radios, allowing each user to virtually "tune" into stations on radios that may not be in the same country.

Background: < hrev53921

Severity: 2 / 4, [functionality] is impaired, because it is often used with stations that do not transmit continuously, i.e. Ham radio listening. It may be difficult to spot patterns without waterfall display.

Steps to reproduce:

  1. Visit hackgreensdr.org:8901
  2. Notice the black waterfall, see the first picture
  3. Quickly switch view to spectrum, see the second picture, so as to avoid a crash
  4. Switch view back to waterfall
  5. Notice the useless blue waterfall that does not indicate power at various frequencies
  6. Ignore the crash, because this is behaviorally distinct as far as I can fathom.

Sorry I screwed up the title. Waterfall on WebSDR is not useful, because it doesn't show signal strength via colors.
