Dear Experts,

We recently found Airspy as a very interesting SDR board for our
purposes.  Our project, some may already know, is to develop 2-channel
(or more-channel) coherent receiver for satellite beacon.  We so far are
successful at 2-ch (150/400MHz) RX with USRP-1.  We now search for new
SDR boards for future expansion.

My question is simple.  We bought 2 units of Airspy.  Now we can run
Airspy on Ubuntu, but do not know how to run 2 units from GNU Radio.  Is
it possible?  Airspy software with Ubuntu consists of several programs.
 For example "airspy_info" can find 2 units on the PC and show info.
"airspy_rx" can run by selecting one of the 2 units.  Running 2
"airspy_rx" programs from Ubuntu seems OK.  However, now we do not know
whether it is possible to control 2 Airspy from GNU Radio python code or
not.  We hope to know current situation and (hopefully) near-future
