Operating Hints for this Receiver:
-- The Sedona WebSDR defaults narrow bandwidth settings to mitigate noise and QRM. You can use the bandwidth settings to make adjustments that work best for you. Save these settings to memory if you want to keep them.
-- The "Memories" function stores the frequency, mode, and your bandwidth settings for the frequency you want to keep.
-- You can use the space bar to mute/unmute this rcvr. Just hold your keyboard's "CTRL" key down while clicking on the SDR "Mute" box. Your spacebar is now a mute/unmute control.
-- If the orange tags are wrong or missing from the tuning dial - it can happen - just place your curser in the waterfall and left-click. Voila!

-- You can directly open this WebSDR to a specific frequency using a customized link. For example,"" tunes to 5000kHz WWV.
