    I'm very familiar with the AD9363 having used it at work for many years.
    The spike in the middle of your transmission looks like a DC offset in the AD9363, which results in carrier leakage. This device has built in calibration which you are supposed to run while setting it up which nulls out the DC offset for the configuration you have just configured. If you change the device setup too far from the starting set up, the calibration needs to be re-run. Or it may be that the calibration sequence failed to converge.

    Treat it like a Pluto SDR. Open it up and compare it to the available ADI schematics for the Pluto, and the other SDR platforms based on the same chip. You should ssh into it and see what it has inside.
    It’s like every other SDR out there based on Analog Devices tech and designs from the Pluto II TO the Red Pitaya

    I got the impression during that satelite contact that one of you was treating the frequency in use as the bottom of your signal, like you were transmitting upper sideband, while the other was treating the frequency as if it were the center of the bandpass for the transmission (more like AM, but I suspect both were FM transmissions. It looked like the bottom of your signal was on the center of his. Most of the satellite transceivers I'm aware of are fairly broad rx/tx systems, as that's about the only way LEO satellites are usable, and I'd expect that the Geostationary satellites are using similar transceiver setups.

    Thanks so much, I have always been wondering if this is a Pluto Plus version with a bigger but compatible FPGA and a proper case. So I wasn't sure if you really got the SDR Console working via the ethernet or if it was the Pluto USB-Driver that emulates an IP link via your Windows client. If I go with such a solution I want to make sure Gigabit Ethernet actually works, because the TRX will not be in my shack. So if I understood correct, the Adalm Plus (also with two TX &RX) is the practically better solution if you are, like me, not a software developer and more on the side of a tinkering end user. Ideally I would love to have TX&RX1 connected to a similar setup you have, a box with bandpass filters, amplifiers, GPS based oscillator, for the QO100 operation and the second port for individual frequencies from 70MHz to 6GHz. But I think so far only SDRangel is supporting dual port operation TX&RX?
    I noticed while showing the VHF Air Band scale plenty of Tetra signals from the lets say roughly 400 MHz region ... so it has serious front end/imaging problems? Does the Pluto Plus also have these issues or is it simple overload or rather a poor PCB design that creates that issue?
    The TCXO on the other side seemed pretty good, I think I heard some 30-40 Hz drift during your demo, which is pretty good for a 2.4GHz frequency. Though I would use the GPS based oscillator via its MCX sockets.
    I'd love to see a comparison of the original Pluto, vs. Pluto Plus, vs. this Libre SDR while receiving weak signals (e.g. far away ATIS, distant ham repeaters on UHF) without any preselection to figure out which one is the cleanest implementation with the least amount of intermod and noise. Currently I see the price of the Pluto plus at 235€ and LibreSDR costs 285€ and the old Pluto is being dealt for some ridiculous prices despite it is the worst implementation without an ethernet port, a stable oscillator, an external oscillator input, only one port of the two that the AD chip offers and the USB 2.0 creates a huge bottleneck when it comes to bandwidth. I have one of the first Pluto's and have been operating it via an USB to Ethernet adapter but its a joke, because it drifts way too much and is not usable without the oscillator mod, which I still have to do. But I may just go for the Plus or Libre and use the old Pluto just for tinkering with amps and UHF antennas.
    What is the maximum usable bandwidth with the two Gigabit Ethernet devices? I know the AD chip can do some 64MHz I believe, but at 12 Bit I/Q this creates a lot of bandwith and needs plenty of math power I guess. I guess the practical limitation will be the interface speed the Ethernet taps in? I wonder if it can do 20MHz, eg. 118-138MHz in one stream?
    Once again many thanks for the very interesting introduction and best regards from Munich, Germany

Currently computers use smart ethernet ports so it would operate with either a straight thru cable or crossed wire cable. You might be able to gain extra access to the radio's memories & electronic controls. 🤓

      Knowing that it's built in China, and not some of the very latest in hardware, it's possible that the manufacturer felt limited by the requirements of China's equivalent of the FCC in the US, to not allow it to work in MW frequencies as it would allow easier contact with people outside of China. Having seen some of the equipment otherwise on the market through AliExpress, I wouldn't be surprised if equipment for export is no longer restricted that way. In any case there are transverters that will allow you to specify a block of frequencies that the LibraSDR will transmit and receive on, that the transverter will transvert down into the MW, and even LW bands. This is similar to how the system he used was able to receive a 10 Ghz signal from the satellite, on a device that maxes out at 6Ghz.

      @TechMindsOfficial  Месяц назад

      @ko4mkp Take a look through my videos for my QO100 build series. I built a NB Transponder and WB Transponder transceiver using an Adalm Pluto as the exciter. For the NB Transponder, which I showed in the video using USB, I was using the LibreSDR to transmit and receive at the same time. Downlink is 10GHz into LNB, 750MHz out of LNB to input of LibreSDR. Uplink consists of LibreSDR into a 2.4GHz Amsat / filtered amplifier (up to about 50 to 100mw) and then the amp goes to a 250 Watt 2.4 GHz amplifier, which then goes off to a Helix antenna on my 1.2M offset dish. Ofcourse with that size dish, I only have to "tickle" the output power slider so I only get around 10 watts at the helix. For DATV, I need between 60 to 100 watts, and even more if I use a higher Sample Rate. But most DATV stations stick to around 333k/s or 500 k/s, but we can go as wide as we want, which takes more power. Hope that makes sense, but go check my build videos.

What I'd be specifically looking for is Turing Completeness and that depends on the programming of the array, so an FPGA is only Turing Complete in some configurations and it's questionable if those configurations would be good enough to handle any load or compete with processors that are designed to be TC.
