SO2R/Caps Lock bind to the secondary radio
When operating SO2R the contester has two radios, two amplifiers, two sets of antennas, but only one computer to log all the QSOs. How to tell the program when typing a call that it belongs to radio1 or to radio2 is the question.
Win-Test uses the [Shift] key to signal to what radio the callsign belongs to. This is a clever way for the operator on the fly put callsigns into the primary radio or the secondary radio but it requires re-defining the numbers above the letters in the keyboard and keep pushing the [Shift] key while typing the call to go to the secondary radio.
Another way is to use the [Caps Lock] key. While the [Caps Lock] key is activated whay you type into the keyboard goes to the secondary radio.
This option does not require redefining the number above the letters in the keyboard.
