    DD0KP Heiner, my layouts for the Pro version of Jean-Pierre F6DZP are already finished. There are two versions for vertical (see picture) and horizontal type of the Serit NIMs.

    I know the board from BG0AUB. In contrast, I do not use SMD components, but only wired ones, which makes the replica much easier. The board fits into an inexpensive housing made of aluminum profile for standard cards (100x160 mm). Optionally, you can use a higher case when installing a display.

    I am looking for a NIM type Serit FTS4335V or a compatible NIM for test purposes. The NIM may also be defective. I need the part to create a circuit board (MiniTiouner Pro replica) because of the mechanical dimensions. Possibly only on loan for a few days :)

    Hi Heiner,

    I know the BATC offer. I am looking for a cheaper supplier who can supply me with small quantities at good prices. Obtaining directly from the manufacturer is also possible, but the minimum quantity is too high for me :(

    I'm looking for a FTS-4335H TV-Module to test my homemade MiniTiouner Pro Board.

    I placed my stripped-down MiniTiouner Pro version from F6DZP on a 100x160mm board (Europaboard), which fits into an aluminum box (see component scheme). Since I am not a friend of SMD, I only used wired components.

    Does anyone know an inexpensive delivery address of this module?

    I'm grateful for any information.

    After making bad experiences with the frequency stability of the much-praised Goobay LNB, I got a Golden Media LNB Type 201+ (about $ 10 on ebay) and replaced the 25MHz crystal with a D75F-TCXO. As you can see in the picture, I connected the TCXO directly to the 6V of the 78L06 (which he tolerates according to the data sheet, hi). I connected the RF output via a 1nF-c to the lower pad of the quartz. Not only has the new LNB proven to be very frequency stable after this mod, but it also provides 5-8dB stronger signals at the PlutoSDR RX input.

    Meanwhile, my Pluto board has arrived. I put it together with my older USB synthesizer in an alu-box and mounted all parts on a board in European format 100x160mm (see pictures). The 40MHz quartz I left in the Pluto board and split the clock line to the AD9363. The more stable 40MHz clock signal from the USB-synti I have fed with a thin coaxial cable directly via C123 into the AD9363 clock input. A test on various frequencies showed a sufficiently good stability in SSB operation.

    However, I had found that my HP PC delivers an "unclean" USB signal, which produced a slightly pulsed modulation of the transmission signal. I connected the Pluto board to my ASUS laptop and this effect was not detectable.

    The next step is the completion of the driver and the 2,4GHZ PA together with my old ATV antennas.

    Heiner, many thanks for your info. I hope I would get my Pluto-Board next week and can start with it. Tomorrow I will try to mount next to the TV-LNB another LBN for the QO-100 and align both accordingly. As Rx I will use an RTL stick with an integrated broadband amplifier.

    Pluto has an USB port through which it communicates with the PC. How can it be that Pluto can also be reached via an IP address? Does Pluto have an integrated WLAN module?
