The ELAD FDM-DUO recieves from 9KHz to 52MHz and covers all the amateur bands from 160m to 6m, claiming an MDS of -132dB and an BDR or +115dB @ 500Hz. Power output is only 5W (!).
Besides being standalone, it can also be attached to a computer so you can benefit from all the power of the SDR technology: big spectrum analizer (up to 6MHz), dual recievers, total control via their SW-2 software etc.
Here's what makes it go:
- ADC: Linear Technology LTC2165 clocked at 122.88MHz
- DDC: Xilinx Spartan 6 XC6SLX25 FPGA + serial flash
- DDS: AD9957
- 2x STM32F4 microcontrollers
What I don't like about it is the fact that it is not concieved as a product, but looks more as a technological demo, made entirely by engineers. The hefty pricetag (1160EUR, about US$ 1600) asks for a good user interface, useful output power and decent build quality, otherwise it will be just a stillborn novelty - interesting from a technological standpoint but not appealing to purchase and use. FDM-DUO's kickass electronics with 100W output and a useful front panel could definetely your main station transceiver.
