Description :

The FLEX-6600 (PC controlled box) and the FLEX-6600M (stand-alone rig) offers the latest direct sampling SDR technology for the advanced HF and 50MHz amateur operator. The FLEX6600M integrates all "6600" capabilities with a stunning 8-inch high resolution touch display and ergonomic controls to deliver a very high performance software defined radio with a traditional radio interface. The transceiver, with the same FLEX-6400 / M base features, add a set of contest-grade filters (7th order preselector), ultra low spurious emissions, and the ability to operate full duplex cross band on two antennas let you transmit on one band while receiving on another, no external equipment required. Even switch to synchronous diversity reception when needed to help you pick out the weak ones in the midst of QRM. Other features:
