Playing with the ADLM-Pluto

The Analog Devices ADLM-Pluto is a fascinating SDR.

It works well as a standalone device using an USB on-the-go cable and a USB Wireless Dongle.


Some interesting experiments :-
  1. It works over a wider frequency range than claimed but how much performance degredation you will get is not clear. The specified tuning range is 300 Mhz -3.8 GHz by tricking it into thinking it has a AD9364 rather than a AD9363 This gives an effective range of 70Mhz to 6GHz. This is certainly out of specification usage but it seems to work. I can't say what the effect on performance but it certainly works in the FM radio bands. I have used it to listen to BBC  Radio Solent on 96.1 with no problems. Please note that the AD9364 can draw more current than the AD9363.
  2. It theoretically has a single processor variant of the Xillinx ZC7Z010 however it can be told to run with two processor and seems to work fine as a dual core. (Most 7010-s are dual core) However it might have a defective second core and have been sold cheap to ADI for use as a single core chip so enabling the second core may be risky. See  https://www.plutosdr.com/viewtopic.php?f=7&t=11 to see the trivial command to do this.
  3. It works with a very recent version of gqrx on linux.
  4. It works with sdrsharp and a special driver on windows.
I will extend this as I learn more.
