Operating Hints for this Receiver:
-- When you sign in, the "Memories" function will recall and display your previously saved frequencies, modes, and bandwidth settings.
-- You can use the space bar to mute/unmute this rcvr. If you hold your keyboard's "CTRL" key down while clicking on the SDR "Mute" box, your spacebar becomes 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!
