"grc" was changed a bit back to "gnuradio-companion" because of a
naming conflict. Is that available?

GRC is now called gnuradio-companion due to a naming conflict with an
existing program.

What would be involved in running this with a USRP2 and WBX?

Download, compile, run. You should plug an antenna in at some point in

If you aren't using UHD yet, you'll have to download and install UHD and

When I run the (modified) code, RAM is slowly (but surely) consumed with

please change the "prefix" variable in this grc graph to the
absolute path of your gnuradio tree.
Eg, in my machine it is
"/home/anastas/gnuradio_trunk/"
Also, you might want to put a throttle somewhere.

Hello,
I am trying to find out the minimum/maximun input power of the ADC LTC2284.
I know that the maximum input voltage is 1 Volt, 0.707Vrms, but what is the
input impedance? so that I can calculate the maximum input power as:
minimum input power (SNR ADC) = Maximun input power
( [(0.707)/(2^1
Nick,
is it thinkable to operate the decoder at a lower sample rate ?
(e.g. at 2 MS/s or even less)

Hi Marcus,
-10dBm corresponds to 100µW. With an input impedance of 100Ohms, since Pmax
rms= (Vmax rms)^2 / R, --> Vmax rms= 0.1 volt
So, if I am right the maximum theoretical voltage at the input of the ADC,
if 0 dB gain is set in the transceiver (XCVR2450 in my case) and noise

Mode S operates at 1Mbit/s bit rate, and being pulse-position-modulated
the data rate is effectively 2Mchips/s. In order to guara

I found this reference

in a Eric A. Cottrell message that explains why we need an high sample rate:

Hello,
Articles I read say that a 10MSPS rate gives better performance that a 8MSPS
rate. I used the 8MSPS rate and still got good performance.
The oversampling is used in determining if the pulse is valid or part of
interference. Some receivers use a huge ROM lookup table to convert all the

Tom,
I have to agree with Steve. I wanted to go to SDR10 in DC but I am afraid the
registration fee kept me from making it. I also would love to offer my center
as a location for a possible meeting. We are in Albuquerque. We are walking
distance from the airport and have many very inexpensiv
