Hew,
Aren't you the guy how figured out how to get the ADC data from the
CX23881 card into the PC? I found your website
http://www.geocities.com/how_chee/cx23881.htm and looked at the data. I
think I'm going to get one of these cards to play with. What model
number do you have? I can find
23881.htm can't compile and run in
Linux kernel 2.6 and is not hooked up to GNURadio. It was developed
using Knoppix Live CD 3.4 running kernel 2.4.x.
Best regards,
Hew

The fastest thing you can do is make a dedicated partition and read and
write it directly. This is very simple (open(), read(), write(),
seek(), etc). I typically dedicate the first 1024 blocks to storing
info about the files. I use one block per file and the first block
stores info about th
I just bought one of these as well. Right now there is a guy on eBay
selling a load of them (with no accessories) for $50 each plus $5
shipping. Here is the only mod info that I've found on the 10.7 MHz IF:
The buffered 10.7 MHz IF Output is available at the emitter of
transistor of Q85. Q8
I got my USRP running today. The first test I ran was the usb speed
test in the examples/usrp folder. It will do up to 16MB/s. The 32 MB/s
transfer fails. This is a dual Opteron system with 4G of memory running
Suse 10.1. Any advise on getting to 32 MB/s. I don't remember what
chipset is
Unfortunately the motherboard does not have USB2.0 built in. Why do the
add-in cards have a speed issue?

I currently have a USB2.0 PCI card based on an NEC chipset. It can only
do 16MB/s. Does anyone know of a PCI USB2.0 that has been used with the
USRP at 32MB/s? I choose the NEC based on it's Linux support but I did
not know that the NEC chips have the worst performance on the PCI cards.

Make a dedicated partition on the drive that you use exclusively for
recording data. You can either read and write the partition directly
(i.e. no filesystem) or you could format it with a filesystem (xfs,
reiser, ext2, ext3). Most people prefer keeping things easy by using a
filesystem so le
