Our Favicon
Our "favicon," the small image which generally appears in the browser address bar or on tabs for a given site, is the International Code of Signals (ICS) flag which stands for both the letter "K" (KILO in the NATO alphabet), and for the message "I wish to communicate with you."
The same messages can be communicated by signalling the letter "K" in Morse code via signal lamp. (While a proper signal lamp may be ideal, a flashlight, probably best employing red LEDs, will certainly fit the bill).RFCafe.com Edited by Kirk Blattenberger
