   * 1x ADALM PLUTO SDR (56 MHz bandwidth) - note this [[https://www.quantulum.co.uk/blog/private-lte-with-analog-adalm-pluto/#|requires FW reflashing, rebuild SoapySDR and possibly using external clock]], otherwise wonky due to lack of timestamping and bad oscillator Rakon 513371 with an accuracy of +/- 25ppm (should be +/- 0.25ppm for LTE), avoiding sluggish original IIO daemon
-  * 2x HackRF (20 MHz bandwidth, only half-duplex)
+  * 2x HackRF (20 MHz bandwidth, only half-duplex, not suitable for some functions)
   * 1x BladeRF (112 MHz bandwidth)
   * 1-2x LimeSDR (61.44 MHz per RX/TX port, so 2x61.4MHz RX; 2 RX and 2 TX ports, RX ports have 3 antennas each, TX ports have 2 antennas each)

+  * 1x LimeSDR mini (not tested yet)
 Currently working with Pluto, HackRF and LimeSDR.
+<note>
+Pluto is not supported out-of-the-box. It has drifting oscillator and no timestamping. There is a fix (requires flashing firmware, rebuild of soapy, changing or using GPSDO as clock) - [[https://www.quantulum.co.uk/blog/private-lte-with-analog-adalm-pluto/ | blog detailing changes required ]].
