built properly). Also, 21 out of the 27 ctests are failures.
Any help would be appreciated.

Hi,
My setup consists of two X310s - one transmitter and one receiver -
connected with SMA cable.
The receiver code has been independently tested by capturing the AP packets.
The transmitter code was tested in a software loopback with the receiver.
The gains on both sides were adjusted such that

I am using the floating type values to generate the samples using matlab.
Am I correct in assuming that gr_complex = float16(half-precision IEEE 754)
+ iota*float16(the Q sample) ?

Hi Marcus,
I am working on a Core i7 8GB system, I dont know if its underpowered, if
it is I have access to another Corei5 16 GB station.
I know this is going to sound dumb but,
how does the USRP sink go into burst mode, I was under the impression that
USRP could only transmit data continuously.
Hi ,
I was working on the transmitter of gr-ieee80211. I will first explain my
setup and then go on to detail the problem.
Setup :
X310 (transmitter) -> SMA cable -> Attenuator -> SMA cable -> X310
(receiver)
The transmitter runs the wifi_tx.grc. The receiver runs the wifi_rx.grc
The tx gain was
Hi,
I wrote a matlab scripts that generates the wifi packets for a given
payload.
The output is of the format
I dumped the output in a bin file.
It is my understanding that the complex type file source reads the input
(bin) file in a gr_complex data type format ie reading 32 bits from the bin

Hi ,
I was reading up about the architecture of GNU Radio. Its primarily an
inheritance based architecture, the blocks that pass data to other block
are actually implemented as subclass and superclass pair. Am I right about
this?
Also whats the need for the flowgraph to be a subclass of the
Hi ,
I was working on the Wifi Transceiver Flowgraph. I created a loopback in
the flowgraph itself to be sure that atleast the transceiver works in
theory. It did work like magic.
Next I replaced the loopback with a uhd source and sink and connected the
RF frontends using a SMA cable. It fails to

Hi community ,
I was wondering if there is a FPGA image compatible with the NI-USRP
2943 available ? and how do i backup the pre-installed NI fpga image .
