Just read this on a UK supplier's website:
The FLEX-6700R™ Signature Series receiver is based on a new
hardware architecture and SmartSDR™ software platform. This hardware
uses Digital Down Conversion (DDC) to convert from RF to digital. The
FLEX-6700R uses two 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, filtering, and audio stream
management. The result is incredible receiver dynamic range and
received signal clarity.
The FLEX-6700R model
receiver utilizes two SCUs for reception from 0.33 to 77 MHz plus 135 to
165 MHz and the ability to create up to 8 full featured independent
SLICE RECEIVERS. Optimized preselector filters can be selected for the
ham bands for greater out of band rejection.
SmartSDR
is the “ecosystem” of the radio platform. It organizes all the signal
processing power in the radios into an advanced radio fabric. SmartSDR
understands the capabilities of each SCU and how to harness its power.
It also comprises of the “presentation layer” or GUI client that the
user interacts with. The FLEX-6700 utilizes an Ethernet connection for
high-speed “driverless” access to the graphical user interface (GUI).
Now I know there are people around with too much money and there are
some applications when a very good receiver may be of benefit, but would YOU spend
£4799.94 on one? This is just the receiver remember! No thanks. I'll continue to build simple rigs for a few pounds and accept their limitations.
