students working on it, it should not be a problem. Single part price is $79
but I expect Arrow may give a significant price break for a university.

Try http://www.l-com.com/. A new packaged 1W amplifier for $130 seems
reasonable to me. Anything over 1W is ...available only for export,
military, licensed amateur radio and OEM component sales and are not offered
for general sale within the USA.

For a general purpose linear amplifier, it is hard to beat minicircuits.
Just be careful not to overdrive it, they get toasted easily.

The problem with many of these types of appliances is that they include
MODEM functions inside the module. For use with a USRP, you will need to
dissect them to get to the physical interface to the powerline.

Two issues:
1) Large resistors results in large attenuation. This circuit attenuates
120VAC to ~5V for the microcontroller.
2) You would need to un-ground all of the components (USRP + PC + you) and
float everything to somewhere around 60V

The easy button to interface to the AC plug would be to pick up some old
power line telephone extenders from Radio Shack and cut them open. You
could then use the basic RX and TX cards.

Has anybody looked at using the CORDIC approximation for atan2? Depending
on the required accuracy, this may dramatically improve performance in your
C code. Ultimately, you can implement the CORDIC functions in the FPGA
(quasi math-coprocessor style) which would then give you the fastest
I have noticed that there are some fixed frequency spurious signals in my
N210. These spurious signals are probably associated with the harmonics of
the clock. If your DC component is at some nice even frequency like 2GHz, I
would suspect a spurious signal to be the cause.

nuisances.
Again, I am impressed with the level of commitment and the work that the
team puts into to improving an already great product.

I think the ADSB project on CGRAN (https://www.cgran.org/wiki/gr-air-modes)
implements a PPM demodulator. I have not confirmed this but it seems like a
good place to start.

Running uhd_fft.grc again produced no change to the measurements.
Can anyone tell me what mistake I am making?

the
performance? For example, does running the sequence uhd_cal_tx_iq_ballance,
uhd_cal_tx_dc_offset, uhd_cal_tx_iq_ballance, uhd_cal_tx_dc_offset produce
better calibration than just the sequence uhd_cal_tx_iq_ballance,
uhd_cal_tx_dc_offset?

Has anyone updated (or in the process of updating) the BBN_80211 or FTW_OFDM
project for UHD support? If you could share them with me, that will save us
the effort of duplicating your work and would be appreciated.
