Operating Hints for this Receiver:
-- On SSB this SDR defaults to the narrow bandwidth setting to mitigate QRM and noise. On AM, the default is "AM/Wide." Use the bandwidth adjustments as necessary to suit your ears.
-- The "Memories" function stores frequency, mode, and your bandwidth setting for that frequency.
-- 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.
