The aim of the Portsdown project is to provide a definitive DATV project which offers an easy way to “get on air” at a relatively low cost, cover most of the common modes and involve some basic construction. It will enable an amateur operator with little or no knowledge of Digital ATV to construct the hardware elements, load and configure the software and use the system to send live Digital ATV signals across town on his existing aerials. It will include the new DX RB-TV modes and the ability to receive and transmit to local repeaters using the more traditional 2 and 4 Msymbol DATV modes.
