 The Flex-6700 out of the box and how it saounds by K6TU, Stu.
14 May, 2013 – Stu Phillips, wrote: …… “As soon as I got the email alert that the package had been delivered, I hustled home and started unpacking……….. With the 6700 connected to the antenna via my amplifier, I made a test tranmission to set the output power and then started tuning for someone to work.” -

Poi K6TU più sotto scrive: “Il primo QSO è stato con un IT9 nel sud Italia. Con entrambi i segnali di S8 è stato un piacevole QSO ed ho ottenuto un controllo di “audio ottimo” in risposta alla mia domanda: “how does it sound?” (come è il suono del Flex-6700?)

FlexRadio 6700 experience at N6V – IDXC April 2013 (report by K6TU)

Sempre K6TU, Stu Phillips racconta le prime esperienze già fatte con il Flex-6700 durante l’attività di N6V (Speciale Event Station) attivata alla 64th IDXC 2013 (International DX Convention is held every April in Visalia, California US). Come si può leggere dal link più sotto Stu ha scritto un interessante articolo che, vista la lunga attesa per questo nuovo SDR Flex, può essere  interessante leggere dato che è scritto da pochi giorni per un ragguardevole “assetto” che si può vedere anche dalla foto qui sopra! // ……very grateful to the following folks who helped me put on N6V in 2011 and 2013.

• US Tower brings along a heavy duty mobile tower (55’)
• SteppIR supplies and assembles the antenna on site (DB-18E)
• M² Antenna Systems supplied the rotor (Orion 2800) and cables
• RF Concepts supplied an Alpha 9500
• FlexRadio Systems supplies the Flex-6700 radio

I’ve used every major brand of radio in the 40 years……  the FlexRadio System Flex-6700 evaluated as the best receiver K6TU has used in 40 years of amateur and professional experience regardless of the tranceiver costs!
………….. The filters perform!  You can pull signals out of a busy band that are really weak – even when parked next to a very strong station….

FlexRadio Systems Flex-6000′s radios will start shipping  from mid/late-June

The new Flex Radio SmartSDR™ software running on a very THIN client.
Ad oggi le notizie dicono che la produzione è in corso e il software è in fase di test. Flex Radio ha diversi “beta-tester” che proveranno i nuovi Transceiver SDR. Molto impegno degli ingegneri sviluppatori è anche per il modulo “panadapter” che ora è stato molto implementato rispetto al progetto iniziale. – Tutte le funzioni di elaborazione dei segnali e di calcolo per il DSP sono tutte entrocontenute nella serie Flex-6000, contrariamente a quanto avveniva o avviene in altri modelli (come il Flex-5000 etc.) che utilizzano la potenza di calcolo ed elaborazione data sopratutto dal Computer esterno. La nuova serie funziona in “THIN Client”, con Computer anche semplici o via rete Ethernet.

Unlike PowerSDR (es. Flex-5000 etc.) where all the UI and DSP software are combined in one piece of software, SmartSDR™ is a THIN Client – its basically a User interface. - All the DSP functionality  runs on a dedicated processor within the radio itself. SmartSDR™ software running on a very THIN client. – (Clik the pictures to enlarge)

Receivers type: Direct Sampling / Direct Conversion / Multi Conversion

1. Direct Sampling a.k.a wideband: FLEX-6000 Series – HPSDR – Perseus, etc.
2. Direct Conversion: FLEX-5000, FLEX-3000, Elecraft KX3, etc.
3. Multi-Conversion a.k.a. Superheterodyne: Most every Kenwood, Icom, Ten-Tec, Elecraft, Yaesu amd Hilberling (note: latest models use a double conversion system it reduces signal distorsion and provides a high-fidelity RF signal to the builtin DSP processor)
