Hello
We're using several Raspberry Pi 3B + computers mounted inside weather proof boxes with amplifiers
to run Radio Telescopes. The Pi 3B+ can almost keep up with 6 MHz bandwidth (12 MHz samples).
An odroid XU4 can keep up with all samples at 6 MHz bandwidth.
We've the PI3B+with The RTLSDR (3MHz) dongle, Airspy Mini (6 MHz) and the
PlutoSdr 4 to 50 MHz. The maximum sustained data rate with the PlutoSdr
is a little over 4 MHz Bandwidth, without significant data loss.
We like the Power over Ethernet feature of the 3B+ and increase cpu speed compared to the Pi 3 A+.
These are running the full Ubuntu 18.04 pretty well.
