Can multiple FLEX-x000 SDRs (FLEX-5000 and/or FLEX-3000) be operated at the same time using the same computer?

No,this is not possible.  Even though the FLEX-5000 and FLEX-3000 use the same Firewire device driver and multiple Firewire devices are allowed to be connected to the same computer, the necessary logic to enable a particular version of PowerSDR 1.x to differentiate between the two different Firewire based software defined radios has not been added.

The first FLEX-x000 SDR to enumerate the Firewire bus will be the one that PowerSDR recognizes and uses.  If you start multiple instances of PowerSDR, both instances of PowerSDR will use same transceiver; the one enumerated first.

The correct procedure for using two different Firewire based FLEX-x000 SDRs connected to the same computer is to completely shut down both SDRs and wait for a few seconds.  The power up the radio you want to use and allow for Windows to properly recognize the SDR.  Then start PowerSDR.  If you want to use the other radio, shut down PowerSDR and turn off the radio.  Wait several seconds and then power up the other radio and wait for a few seconds. Then start PowerSDR.

It is possible to operate a FLEX-1500 and either a FLEX-5000 or a FLEX-3000 at the same time on the same computer.
