These are N310s. I'm using 122.7kSps as the sample rate in the setup
I'm using. I didn't send the full .grc file because there's 24
embedded python blocks that act as a correlate and shift with the tx
sequence. When I was giving a separate USRP source to each N310 I
could use both Tx/Rx channel and the Rx2 channel of my first N310 at
the same time, but when I use only one USRP source I can't seem to get
the Tx channel to work.

Could you share the complete message log, including errors. This will,
among other things, show us which version of UHD you're running.

want to transmit a calibration tone across the array from the
TX channel of the first USRP (addr0), but when I add a USRP
source block it gives a 'device already claimed' message.
This doesn't happen when I make individual USRP sink blocks
for each USRP in the array.

Could you give more details of your hardware configuration. Are
these N210s? X310s?
Also, I'll note that 32K as a sample rate is well below what is
normally supported--do the start-up messages complain about that?
