You might want to put a space in your QTH. Now hold the Function Button down for two beeps and enter your name the same way. Rags will remember it forever, even if your power down. Rags just one more beep and your call will be stored in nonvolatile memory. When you have finished entering your call sign, give Mr. Please note, that whenever you are entering data with your paddles, three beeps is the same as backspace. If you make a mistake, hold the Function Button down for three beeps. Each character will appear after you send it. Don't worry about speed or gaps between letters. Now, using your keyer paddles, send you call sign in CW. Hold the Function Button down again for one beep. Press the Function Button and release it after a single beep. Rags knows that, you can have access to everything. Rags will keep coming back to Configuration Mode until you have set up one important user setting. If you hold the function button down for more beeps than those listed, you will back up one menu.īacking out at this point will just put you here again. This is the only menu where this instruction is provided, but the same is true of all menus. The last line: “PRESS LONGER TO EXIT” simply means that if you hold the button down for four or more beeps, you will exit this menu. This means that you hold the button down for one beep to edit User Settings, two beeps to edit User Macros, and three beeps to edit Keyer Settings. You will count the beeps and release the button after the desired number has been reached. You will need to hear beeps when you hold the Function Button down. Make sure that you have either plugged in headphones or have attached a speaker to the header pins on the board. There are also header pins on the board that you can use to connect your button if you chose to create an enclosure for the keyer. It is very convenient to use because you can press it down or rock it any direction, front or back left or right, to activate it. This button sticks out off the edge of the PCB next to the LEDs. The secret to navigating menus is the single Function Button. Rags, it knows that you have not configured any settings so it will automatically enter the configuration mode and the following menu will present itself: If you've read this far, you may be interested in the older version of this tool which does not attempt to adapt to the sound and also includes more diagnostic information.When you first power up Mr. The volume threshold is the value (0-255) which the measured volume in the analysed frequency must exceed to be counted as a dit or dah. The volume filter (which uses dB) discards very quiet (very negative) or very loud (close to zero) sounds and scales the size of the remaining data. There are three parameters which are not automatic: the minimum and maximum volume filter settings and the volume threshold setting. The frequency can only be certain values and the closest allowed value will be chosen. If you want to fix the frequency or speed then click on the "Manual" checkboxes and type in your chosen values. In fully automatic mode, the decoder selects the loudest frequency and adjusts the Morse code speed to fit the data. From these timings it determines if something is a dit, dah, or a sort of space and then converts it into a letter shown in the message box. If the volume in the chosen frequency is louder than the "Volume threshold" then it is treated as being part of a dit or dah, and otherwise it records a gap (this is shown in the lower graph that looks like a barcode). The spectrogram of the sound is shown in the main graph along with a pink region showing the frequency being analysed. The decoder will analyse sound coming from the microphone or from an audio file.
