I admittedly get a little frustrated when someone comes into the shack unannounced. It's not that I have anything to hide, but rather that it's sometimes a little jolting when I have my headset on, am in the middle of an intense QSO, and my wife taps me on the shoulder.
Note that I have it set to just light up, no sound.
My solution is a simple remote alert product I bought on Amazon. In case you'd like to try it, here is the link.
