Is it possible to switch the 2nd RX input / TX output?

Not at the moment. As PLUTO doesn't have external antenna connectors for RX2/TX2 I have not added support.

Apologies. Misunderstood query as assumed meant a 2nd hardware radio.

pluto rev c HAS connectors for rx2 tx2 ... but those have to be switched on the be active with a fw hack (see here)

https://wiki.analog.com/university/tool ... ustomizing

scroll a bit down to "updating ad9364"
there you find that when you have a rev c ... with fw 0.32 (or newer) ... and set the tuner to be ad9361 you can set mode to 2r2t

fw 0.32 rev C mode 2r2t 2 Rx, 2 Tx, 30.72 MSPS max data rate
(requires ad9363 or AD9361 settings)

so a second rx and tx port is possible if you have a new pluto

As you say, a hack. A revision c/d would be interesting to play with, sadly no way of buying one :( .

why not?? ... rev b is out of stock ... mouser and digikey now sell rev c/d (but the price also has gone up)
i still modify them (with better tcxo and a metal case) ... even if you can use now an external reference (gpsdo or ocxo) i mount a stable clock inside
problem is that the new tcxo has no enable pin (to switch off when using external reference) .. but i found a good solution
the 1.8v regulator ic also has an enable pin ... 3 cuts with a sharpie and 2 wire bridges later i can switch of the power to the tcxo
instead of direct switching xo/tcxo off via enable pin i switch the 1.8v that is powering the tcxo ... same result ... when using the external reference the internal is switched off
