? The manual can be downloaded from??and the product page with other details can be viewed at? ? Included with this sale are the transceiver with a BNC dust cover.? You will need to provide a 5.5mm with 2.5mm pin power cable; remember that this radio is rated for between 5.5V and 13V, so powering it from a Talentcell or a PD 12V cable (or a 9V battery) would work. ?
