Tech Minds: Testing the Pluto Plus SDR

The "Pluto Plus" (aka Pluto+) is an unofficial and upgraded version of the Analog Devices ADALM Pluto SDR. It is currently available on Aliexpress and Banggood stores. In his latest video Tech Minds reviews a Pluto+ SDR that he has received, noting that it has all of the features that should have been in the original Adalm PlutoSDR.

He notes that the PlutoSDR+ has various improvements over the PlutoSDR such as that it comes in a metal enclosure, has four SMA connections (2x TX, 2x TX), a Gigabit Ethernet connection, a microSD slot, external clock input, 0.5PPM TCXO, fine tunable clock via resistor, a PTT key port and a DFU key.

In the video he goes on to show how to set up the PlutoSDR+ before testing it out on a QO-100 satellite setup, noting that it works perfectly and without any signal drift noticed.

    Pluto+ has a litle bug: cheap Balun B0310J50100AHF 300MHZ-1GHZ instead of TCM1-63AX 10MHZ-6GHz . That cause lack of sensitivity. Additional MOD is necesarry necesary.

      If you look at the datasheet for the B0310J50100AHF it does show the expected Wide Band Performance from 0 MHz to 8000 MHz. So they will function, just with less than ideal performance, when operating outside of specification. At a guess that exact part was chosen not for ideal performance but to make a price point possible.
      On mouser 4000 TCM1-63AX+ @ €5.14 = €20,560.00
      On mouser 4000 B0310J50100AHF @ €0.307 = €1,228.00
      More than an order of magnitude cheaper. If you can knock a zero of a price of a final product it becomes attractive to a lot more consumers. More sales at a lower profit margin usually trumps lower sales with higher profit margins (outside of government work).

    how do you setup the software side (sdr angel) with network connection of Pluto ? is in sdr angel pluto+ ethernet supported or is it like a USB-Network Adapter ?
