FDM-DUO – the DDS SDR design and build quality is Italian quality!

The FDM-DUO that provides an advanced Direct Digital Samplin (DDS) SDR Compact HF 50MHz QRP Transceiver. Covering all bands from 9kHz trough to 50MHz, with 5 watts RF outup and multiple receivers.  That can be used in standalone mode (not PC) or it can be entirely computer controlled – The design and build quality is Italian quality !


 Standalone OperationG4WNC, Mike wrote on the RadCom of March 2015: The large knob provides the main tuning and this can be set to operate with a wide range of tuning steps from 1 Hz to 1 MHz . If you’re using the rig in standalone mode, you just need to connect power, antenna and mic/key and you’re in business. (! more: please read the User Manual)


Computer operation – The real flexibility of the FDM-DUO was realised when I combined the rig with the Elad FDM-SW2 SDR Software on external PC – I had access to up to 8 software receivers plus the standalone receiver making a total of nine, which is more thanI could ever use!


G4WNC, Mike wrote: If you were a datamodes fan or contester, you could have one receiver tuned to the PSK band segment and the audio routed to an instance of FLDIGI. You could then have another receiver set to the RTTY segment with a RTTY decoder. You could also have CW Skimmer running on another receiver checking out CW activity on the band. … You could then duplicate this setup on the second DUO channel, which could be tuned to a different band! – (!! nrd…. maybe you need many ears! hi)


The antenna signal is applied to some ESD protection and 5 anti-aliasing filter before being passed to the main analogue to digital converter (ADC). Elad use the popular LTC2165, 16-bit ADC thet’s clock at 122.88MHz to provide confortable sampling (serial data stream runs at just under 2Gb/s) of the entire RF spectrum to 9kHz through to 54MHz.


Elad uses a Xilinx Spartan 6 FPGA and the decimated outup in standalone mode is 192ksps and the tuning range wold be abaut 180kHz (output of the Spartan 6 is passed to an STM32F429 ARM microcontroller) – However, when operating the FDM-DUO using the included FDM-SW2 software, the decimation range can be changed in six steps up to a maximum of 6.144Msps.

A proposito di parametri di test e di confronto nei vari ricevitori per HF di tipo supereterodina tradizionali oppure di tipo digitali SDR leggere quanto scrive Adam come riporto qui sotto e poi su QEX n. 3-4 2015.

QST April 2015 reviews the FLEX-6300 nad FLEX-6700 two SDR Transceivers products FlexRadio Systems made in USA (! Note: to access this resource you need to ARRL log-in)

QST-3-2015I tradizionali valori di DR3 (3rd-Order Dinamic Range dB), IP3 (3rd-Order Inrcept Point +/- dBm) e di Dinamica di blocco (Blocking Gain Compression dB) sono “numeri” poco validi nel contesto di una radio SDR a campionamento diretto. (-dBFS per un ADC converter) –
Per questo, Adam Farsom, VA7OJ ha proposto di usare come standard il metodo IFSS (Interference-Free Signal Strength) per il test IMD (Two-Tone Intermodulation Dinamic Range) in ricevitori a campionamento-diretto (Direct-sampling SDR). – Adam, VA7OJ wrote a terrific article in the latest March/April 2015 issue of QEX Magazine. – I wish ARRL would standardize on tests, and preferably use the (NPR) Noise Power Ratio test methodology.

HAM RADIO 2013: FDM-DUO – HandyPSK – EXPERT 1.3K – Exacalibur ULTRA – K3/0 Mini – FT1DR C4FM – PT-8000 & More


Ham Radio 2013 – The International Exhibition for Radio Amateurs, HAM RADIO 2013, was held June 28-30, 2013 in Friedrichshafen, with exciting new models and products! – Here are  some photos and news  from the tour…! – FT-1DR FDMA Mode like NEXEDGE™ Kenwood’s or IDAS™  Icom’s Digital PMR’s Radios. See the new FT1-DR brochure –   Fiera di Friedericshafan 2013: un report con varie foto e descrizione di alcune novità  – See more & Link below!

FDM-DUO a new SDR rtx made in Italy – ELAD has displayed his “little SDR Tranceiver” at Ham Radio Friedrichshafen 2013. Quite interesting concept to have a stand alone QRP rig at 192kHz sampling, combined with an extended SDR if you use it with a Computer.


It is a Direct Sampling SDR receviver (is an RF Sampler) with a DDC on a FPGA, and a Cortex ARM DSP module for filtering and demodulation in stand-alone mode. In RX and TX directions it is a fully SDR technology. QRP trasmitter 5 W Output Power – CAT Control via USB-2 port dedicated.  (please click image to enlarge)

FDM-DUO_rtx-Elad-2013In other words: you can take it with you as a self-sustained 192kHz SDR narrow band modes QRP tranceiver (Sideband/CW/AM). –
At home, attached to a faster CPU (computer with FDM-SW1 software o so), you can run it at its full bandwidth of 6144kHz sample rate and use wider bandwidth RX/TX modes, inc. DSB, AM Sync, FM, RTTY, DRM, WB FM+RDS.
