FLEX-6700 description :

The FLEX6700 "Signature Series" transceiver (see the FLEX-6700R as receiver only) is based on a new hardware architecture and SmartSDR software platform. This high performance software defined radio uses Digital Down Conversion (DDC) to convert from RF directly to digital and Digital Up Conversion (DUC) to convert from digital to RF. The FLEX6700 utilizes Spectral Capture Units (SCU) for the RF to digital conversion and an ultra-high performance on-board signal processing and control system to perform demodulation and modulation, filtering, and audio stream management. The result is incredible receiver dynamic range, ultra-low phase noise and phenomenal received signal clarity.

The transceiver utilizes two SCUs for reception from 0.03 to 77 MHz plus 135 to 165 MHz and the ability to create up to 8 full featured independent Slice Receivers. Since the radio has two independent SCUs, it is capable of diversity reception. Optimized preselector filters can be selected for the 160-6m (except 60m) ham bands for greater out of band rejection. The FLEX-6700 provides continuous duty 100 Watts output across the entire 160-6m band, with RD100HHF1 MOSFET push-pull PA and 11 half-octave low-pass filters, along with an automatic antenna tuner (ATU) capable of tuning antennas over 10:1 range (3:1 on 160m and 6m), and more the radio are capable of very low power transmit anywhere (from 100 KHz and up) it have receive capabilities.

In the FLEX 6700 two Analog Devices AD9467 ADC converters operating at 16 Bit / 245 Msps are capable of digitizing the entire HF spectrum in real time. Also the transmitter architecture are full SDR with the Analog Devices AD9122 DAC converter operating at 16 Bit / 491 Msps. SmartSDR is the software "ecosystem" of the radio platform. It organizes all the signal processing power in the radio into an advanced suite. SmartSDR understands the capabilities of each SCU and how to harness its power. It also comprises of the presentation layer or lightweight GUI client that the user interacts with. The 6700 is also equipped with a 1 Gb Ethernet port suitable for any type of PC and also for network devices. The use of the FLEX-6700 remotely thus becomes independent of the computer, simply connect it to the Internet via the Ethernet port in order to operate it from anywhere.
