FLEX-6600M Signature Series SDR Transceiver

The FLEX-6600M offers the ultimate performance direct sampling SDR technology and the best value for the serious HF/6m operator. FlexRadio continues to set the standard for high resolution, real-time spectral display in amateur radio transceivers.

The FLEX-6600M integrates all FLEX-6600 capabilities with a stunning 8-inch 1920 x 1200 IPS WUXGA touchscreen display and ergonomic controls to deliver the top performing Software Defined Radio with a traditional radio interface. It delivers unmatched band awareness from the integrated display while providing an external HDMI compatible connection to a 1920 x 1200 resolution monitor for maximum spectral visibility. Influenced by top contest/DX operators, The FLEX-6600M symmetrical dual VFO controls are strategically placed to provide maximum productivity in chasing rare DX, winning contests, digital mode fun, or even casual operation. It’s all self-contained so just plug it in and operate — no PC, network or learning curve required. An antenna tuner is included.

Contest grade filters, 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. By adding FlexRadio’s new Power Genius XL™ LDMOS solid-state amplifier a complete legal limit, all mode SO2R station is now practical with one radio, one amp and only three interconnect cables — half the cost and none of the complexity.

FlexRadio’s industry-leading SmartSDR™ software offers compatibility across the entire FLEX-6000 Signature Series family to deliver continuous leveraged software enhancement. And you can use the latest SmartLink™ technology to access your radio virtually anywhere from any SmartSDR compatible client with only a login and password — even your iPhone.
