The DX20 and DX18 are no longer available and not back order available the will be new line of radios like the ix 12 but more channels the ix12 right now is capable to be the 18ch radio . So be ready for something new for this year,I’m using the QQ dx18 and the dx18 Stelth both are great radios , I don’t use the voice thing it’s just annoying just sample timer vibrate and bip noise.
