The letters in blue sc-m, Emg &sps , dw how do you enable them ? I know that if i long press emg it takes the ht to 446.000 or something and does an emergency beacon in cw. Also when your in the menu and press F/W it adds a star symbol to the menu not sure what that is about ? Maybe someone with experience can answer ? It was a break through learning the fpp and aprs etc. The manual is really boring and if i could get a pdf versian i could use ctrl+f to find the answers.
