OVERVIEW
The FLEX-6700R Signature Series software dened receiver is built for the
most demanding receiving application where ultimate performance is key. The
FLEX-6700R receiver is built on a digital direct sampling receiver foundation.
By removing analog mixers and components, the FLEX-6700R provides an
ultra-quiet receiving platform for the most demanding applications.

OCXO
With dual spectral capture units (SCUs), the FLEX-6700R allows multiple active
antennas and provides reception and unprecedented spectrum visibility across
up to eight panadapters and waterfalls. The FLEX-6700R’s multi-stage RF
preampliers enhance weak signal reception up through the VHF bands. This
coupled with the incredible realtime DSP processing capability inside the radio,
allow the operator to view signals well below the “noise oor” while effectively
eliminating adjacent interference.
At the heart of the FLEX-6700R is FlexRadio’s SmartSDR™. This is the dawn
of High Denition (HD) visual radio -- Radios that “see” as well as they hear. A
decade ago FlexRadio Systems pioneered SDR for the amateur radio market
and set the standard for visual radio interaction. Today, SmartSDR sets a
new bar for visual radio display and control. Following the simple is better
rule, we built a new graphical interface that is easy to learn and use. Multiple
high-denition, real-time spectral displays are at the heart of the SmartSDR
experience. Intuitive controls are hiddeen from view to minimize clutter yet are
instantly available when needed.
SmartSDR is built from the ground up optimized for network bandwidth and
control. By placing key processing elements inside the radio hardware,
SmartSDR can reduce the amount of data transmitted over the Ethernet
network that connects the radio to the client software. Because of the
concentration of data tha occurs before data is sent to the client, SmartSDR
performs seamlessly in network situations where other radios simply can not
perform. SmartSDR’s networking capabilities, now and in the future, will enable
use in the shack, across the house or around the world.
