Galaxy DX33HP 2 HAM radio is the new version of their older DX33HP and DX33HML models.
With the new edition 10-meter amateur radio, Galaxy has stacked the echo controls onto a single control knob, which leaves room for the microphone jack to come out the front of the radio as opposed to the side. They've also added a variable dimmer control that lets you turn down the intensity of the lights including the RX/TX LED and have also added a control that allows you turn turn on/off the talkback.
These three changes make this a much more convenient radio for most trucks. The Galaxy DX33HP 10-meter amateur radio will fit easier into tighter areas where having a mic cord sticking out would be an obstruction and being able to dim the blue lights will help those who do a lot of night driving.
