    Good day!
    I want to present three large projects, each of which is an independent unit of SDRs, which does not require the use of a PC.
    The first project is the HF radio Peony-DSP (Pion-DSP). The receiver is able to receive in the frequency range 50kHz-30MHz, modulation types - AM, FM, SSB, CW. The receiver has many features such as AGC, NB, auto notch filter, squelch shift.
    Image Rejection of reception - 70 dB, is automatic software.
    The presence of five filters with different widths for each type of modulation:
    AM, FM: 10 kHz, 8 kHz, 6.5 kHz, 5 kHz and 4 kHz;
    SSB: 3 kHz, 2.7 kHz, 2.5 kHz, 2.2 kHz, 2 kHz;
    CW: 1,5 kHz, 1 kHz, 0.5 kHz, 0.3 kHz, 0.2 kHz.
    Squareness digital filters used by the level of -3 dB / -60 dB - better than 1.1.
    A first embodiment of the receiver has been completely assembled at home and consisted of five boards:
    - System board;
    - DDS on the AD9952;
    - SDR board analog receiver;
    - Codec board with CS4221 with ULF TDA2822;
    - LPF board.
    To connect to a PC via an interface USB.
    In further developed variant, consisting of one board.
    The receiver does not require a PC, it is a completely self-contained. Photos of the receiver can see the link http://www.cqham.ru/forum/showthrea...D-DSP-%F0%E0%E4%E8%EE%EF%F0%E8%B8%EC%ED%E8%ЕА

    The receiver has collected several dozen people.

    Continuing spread references and a brief description of these projects.
    #It is a stand-alone SDR transceiver, which does not require the same PC.Transiver called Тюльпан-DSP (Tulip-DSP).
    The transceiver is developed by me and R6DAN, Vladimir.
    The transceiver can send and receive all types of modulation: AM, FM, SSB, CW. She has so many features and hard to describe all the transceivers in a single message. The transceiver is fully developed, repeated several radio amateurs.
    There are two versions of the transceiver - type of analog and direct digitization type DDTS / DIS.
    The reference to analog options:

    The analog version of the transceiver is fully available for self-assembly, some people successfully repeated it.
    If need be, I can lay out other useful information about the projects. There are lots of videos, photos and other information.
    I'm writing text using Google Translator, I hope that their meaning is clear.

    I've been watching this for a while too. It looks like a brilliant DIY SDR transceiver project, I wish more information was available in English

    I was trying to find some information from your 1st post but it seems now that some of the links are broken unfortunately.

    Could you please post some information both about the DDC and the analog versions?

    Where can we find the schematics for both versions?

    Is there a parts list anywhere?

    Are the bare boards available to buy anywhere?

    Are any of the assembled boards available to buy anywhere (the DSP and DDC boards as well)?

    Perhaps the transceiver is available to buy in a kit form, like mcHF or Klopik-2?

    Many thanks for your time.

    For 1st version you can view:
    - controller : http://www.cqham.ru/forum/showthrea...E0%ED%F1%E8%E2%E5%F0%E0-%D2%FE%EB%FC%EF%E0%ED
    - dsp board for analog: http://www.cqham.ru/forum/showthrea...%E2%E5%F0-quot-%D2%FE%EB%FC%EF%E0%ED-DSP-quot
    - dsp for DDC: http://rus-sdr.ru/wp-content/uploads/files/DSP-DDC.pdf

    But it is only for Tulip.
    For VisAir schemes is not for free because VisAir it is full commercial product. Separate boards of VisAir will be availabel ni future soon. Also full assembled VisAir will be sell also soon. It very difficult work that demand very much time.
