Hi All -

I've been using the new UHD driver (003.004.002) stable release w/ XCVR
boards on the USRP N200.

I'm using the xcvr as a transceiver - it receives a packet, then waits a
while before sending a packet. However, I can see some spikes in the
preamble detection stage which seemingly correspond to the time around
which the packet is transmitted. I know XCVR is not full duplex, so I'm
*guessing* it's some kind of LO leakage, perhaps?

On replacing the UHD driver with an old one (003.004.000), the issue seems
to have disappeared.

Any ideas? Attached is a snapshot which shows the smaller spikes
(corresponding to tx) next to the bigger ones (corresponds to the rx).

Thanks,
Apurv
