If it has separate synthesizers then you can take it
to the bank you will have synchronization problems for nulling
applications and the like. For average listening it ought to be
"Pluto level" good.

its a single chip with a single main clock (40 megs) ... so i
guess it could work

If there are two frequency synthesizers
involved you have to play special games to get them to produce
phase coherent outputs.

i guess even when there is a time delay between sample of
first and second port the time delay should be fixed in time
(and could be "shaved away" with software)

i do not know about the phase thingy ... thats a point to
be investigated ... right a minute ago postman brought 3
new ones to the "clinic of doc pluto" :-)
(to be modded with a better tcxo, housed in aluminium
case etc etc)
to investigate the phase coherent and to test things out
you sure need an own revision c/d ... (and modding it to
new tcxo is a tiny bit tricky)
on the other hand the new revision has the option to add
a gps reference .. ext clock in on ipex connectors on the
board .. switching to external with a fw command ...
switching from 1r1t to 2r2t also with fw command ... so
the new revision has not just the second set of rx and tx
ports but also ext clock in and out (a full blown modded
pluto then has 6 sma sockets)

have a new revision Pluto. What would the second
channel be used for? I doubt it’s phase-coherent, it
what about support for second channel in Pluto??
the new revision has two rx and two tx ports ... do
you plan to support the second channel in the Pluto??

There’s only one vote that
matters 😊 . Seriously, were
there a radio with 4 or more channels I could be
very interested, sadly one which was being developed
will no longer be released to the public.

I vote for diversity reception. I really don't like
SDRUno. SDR Console is so much more intuitive.
