KFS WebSDR #2 "lightweight" mobile version  (Omni HF Antenna)
  • This is the stripped-down "mobile" version of the WebSDR page and it should work using Chrome, Firefox or Safari on most platforms.  The "full" version has more features and will run on most modern portable devices.  There is a 2-hour inactivity time-out.
  • Tuning is different from the normal WebSDR:  Do not drag the yellow filter curve, but the waterfall: Buttons are available, too.
  • Touch frequency for numerical entry in kHz;  Touch the mode box to open drop-down to select.
  • If there is no sound, touch the "Audio Start" button below.  Adjust the volume using your device's audio controls.
