Hello,
Is there anywhere the USRP-KNOPPIX Beta, with Alsa fixes can be
downloaded, from?
If not, then can at least someone put up the original USRP-Knoppix Beta release
for download for all temporarily again please?
I cant find it on any of the previous download sites, they are down, that had

If it's reporting overruns then all bets are off.
multi_fft.py implements applies a channel filter to each stream.
Try turning it off. It should be possible from the command line, but
isn't. Change:

For the Basic Rx, 0xf3f2f1f0 is the correct setting to feed 4 separate
signals into the I inputs of 4 DDCs, with zeros fed to the Q inputs.
To use 4 channels, you must use the std_4rx_0tx.rbf fpga image.
If you use the std_4rx_0tx.rbf image, the decimation rate must be <= 128.

i.e. each output bit is either 1 cycle of a 1200Hz wave (1-bit) or 1.5
cycles of an 1800Hz wave (0-bit). The start of each bit is at a
