Marcus,
Sorry for the late reply on this, I've been upgrading my hardware and I'm just
catching up. Here is my issue, in Spectrum lab if I provide a FFT Input length
of 65536 on a 192Ksps stream, I get the following characteristics:
Effect of FFT settings with fs= 192.000 kHz:
Width of one FFT
Hi
Here is the 137 MHz RHCP antenna we have developed
http://www.poes-weather.com/download/jm-dca/
This antenna will give you better performance at low satellite
elevations (horizons).
It is easy to build and you don't have to be that careful.
We don't use a pre-amp if coax < 15 m (loss ~2 dB RG
I guess I got it! The default channel map is such that the first channel is
the UN-fftshifted frequency location which is at 10 Hz (the 5th one on the
list)! Whoo! It would be nice to tell a newcomer about this.

Dear Group,
I am learning to do the pfb channelizer using the now famous example on the
documentation page at:

The example is at the end of the page, where a 9-subchannels are pulled out
of the original 9 kHz bandwidth signal. The original signals' t
Hello,
I got an email from Ettus Research and noticed there is an SDR Conference near
me in Worchester, MA (NEWSDR’13). Unfortunate for me, it is this Friday so I
can not get food or parking because I cannot preregister (link gives an error).
I remember there was a GNU Radio conference in the f

Hi,
It is excited to see the new OFDM implementation has been merged and test
in the GNURadio master branch. Several Questions:
1. What are the main changes from the old design?
2. Seems it support NC-OFDM as the user can arrange the carriers? And how
is the gain of dB between the occupied carrier

Note that you will almost certainly need an antenna amplifier too (unless
you make a huge antenna ;) Even a specialized receiver needs

Hi all,
I want to play with NOAA...Is there anyone here who has already tried it? Can
