Hi,
I was just asking myself the same question but I'm not sure I understood
your answer.
Is it possible to have two output streams of different data types? I want
one to be unsignad char and the other one float or double. How is it to be
coded?

Here's a hastily put together demo of using gcell.fft_vcc in a
usrp/fft gui, running at d=64 and fft_size=2048, using 6 spus:

the ppu usage tops at about 90%. You can trade off d=32 for fft_size=1024.
There is no windowing in gcs_fft_1d_r2.c at the

Hi everyone,
I'm trying to determine the maximum safe RF power I can feed into the
DBSRX and TVRX daughterboards. I have looked at the datasheets, for
the boards' tuners, but I am still not certain enough.
Does anyone know what the maximum safe (no risk of damage to the

I have been browsing the sources for the usrp2, so that I'm familiar
enough with the code when the new usrp2 comes. I have a million
questions regarding it, but there is one simple one for starters. At

Sorry if I'm double posting, but I don't know if yesterday's message
got to the mailing list. I want to edit db_tv_rx.py in order to set
the three aplification gains independently. How do I include a
modified .py file in the Gnuradio installation to make my Gnuradio
application use the new file?

Thanks. So I just reinstall GnuRadio with the new .py file and next
time I use a TvRX daughterboard, I'll be able to access any newly
created functions?

Hi All,
I have been attempting to use a GNU Radio 3.1.2 Virtual Machine (guest
OS is Open Suse 10.2) kindly provided by Chiara De Dominicis, with the
USRP. Initial communications with the USRP were established, enough for
firmware download to the USRP. However when attempting to run any

Hi,
Thanx Eric and Johnathan. I would be upgrading my radio to
3.1.2. But the actual question remains: Is there any way to bring
this incoming RF Signal down to some IF (say 10MHz)? and to get only
real samples?
Nope. Complex
