Ranges & most important specs:</div>
<div>
</div>
<div>
Frequency range: RX 9Khz to 52MHz direct sampling receiver</div>
<div>
TX 160m to 6m others frequency to be defined</div>
<div>
MDS: -132dBm</div>
<div>
BDR: +115dB (500Hz) </div>
<div>
</div>
<div>
Power output 5W MAX</div>
<div>
There is available a secondary SMA connector output with 0dBm level
for</div>
<div>
use or as generator open from 400Khz to 150Mhz (TBD) </div>
<div>
2m VHF RTX will be an option as a board to fit (TBD) </div>
<div>
The RTX have 2 Antenna inputs and can work as single RTX antenna or</div>
<div>
separate RX and TX antennas (selectable by front panel or by CAT)</div>
<div>
Standalone Modes: CW CW+ CW- LSB USB AM </div>
<div>
</div>
<div>
In dual mode PC software can show the 192KHz bandwidth of the FDM-DUO
and</div>
<div>
it possible to demodulate with PC Software and with FDM-DUO with internal
demodulator</div>
<div>
In PC mode the RX bandwidth may have up to 6MHZ and internal demodulator
is disabled.</div>
<div>
</div>
<div>
Refer to SW-2 propietary software for other specifications</div>
<div>
</div>
<div>
This is a Software Defined Radio and these mode can be changed
depending</div>
<div>
on new software that will be available from ELAD or for from who want
to</div>
<div>
use Extio Dlls. For using existing programs like HRD and FLDIGI….
It will be very simple</div>
<div>
to plug the USB for CAT and USB TX like an external sound card.</div>
<div>
</div>
<div>
Front-end</div>
<div>
ADC Linear LTC2165-16bit 122.88MHZ clock</div>
<div>
DDC FPGA Spartan 6 XC6SLX25 + Serial Flash for stand-alone mode.</div>
<div>
USB IQ path through CY68013 for RX bitstream</div>
<div>
(192KHz up to 6.144Mhz single channel and 384KHz dual channel in PC
mode) </div>
<div>
Stand-alone RX IQ path STM32F4 ARM floating point
microcontroller </div>
<div>
LCD Controller Keyboard controller LPC1766 Cortex M3 </div>
<div>
TX modulator use a second STM32F4 Floating Point microcontroller</div>
<div>
+ AD9957 DDS clocked at 368,64 MHz</div>
<div>
Clocking source Si5338 drived by 10MHz TCXO or External reference
input</div>
<div>
TX modulator use I2S sourcing from MIC input (Cirrus CS5346) or USB
input</div>
<div>
(CODEC CM6510B with customized firmware) </div>
<div>
The third USB is a FTDI controller for CAT interface</div>
<div>
</div>
<div>
Firmware upgrade:</div>
<div>
</div>
<div>
Cortex M3 by CAT </div>
<div>
CY68013 by PC</div>
<div>
STM32 RX or TX USB by memory stick through internal dedicated USBs</div>
<div>
FPGA by PC</div>
