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.
-- On the condensed frequency bands with a wider frequency span, click your mouse in the general area of the band you want to hear, and then click the "Max In" button to zoom in and center on that part of the band. Now you can click the "Zoom Out" button as needed to see specific views of your desired area of the band.
-- The RTL-SDRs used on some frequency bands have, by design, limited dynamic range. During "Grey line" periods at Sunrise and Sunset, RTL-SDRs may be intermittently effected by dominant signals from super power shortwave broadcasters. This condition ceases when limited Grey line periods have passed.
-- On AM, interference is almost always on ONE sideband. Using your mouse, grab the left or right edge of the yellow bandpass indicator and pull in towards the carrier frequency...interference gone! Remember, you only need one sideband to copy AM.
-- 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 with a specific frequency and mode using a customized link. For example,"http://w7rna.dyndns-remote.com:18901/?tune=5000am" tunes to 5000kHz WWV in AM mode.
