Glad to hear that you got things calibrated.
I have used my SDR-IQ on Linux as well as on windows.
I had a similar problem to what you describe in August when I installed
a new version of Ubuntu. THings had worked OK before that. Here is an
excerpt from an exchange RObin AA4RC and I had on the SDR-IQ list at
that time. It is structured with earliest text at the bottom, newest
at the top. Let me know if you need more info:
**start excerpted text**
I should have noted in the email I just posted that I added the line
to the beginning of Leif's file /etc/linrad/usb_sdr14
so that the ftdi_sio driver is automatically removed each time Ubuntu reboots.

One of the issues with the IQ is that of USB ID. It uses the generic ID so
the kernel will install the ftdi_sio driver instead of the ft245 driver you
just installed. Do a lsmod |grep ftdi to see if this is the case. If the
ft245 driver has control of the IQ, you should see a line in the system file
/var/log/messages stating that /dev/ttyUSB0 (or another number) is
allocated. If the ftdi_sio driver is installed, run rmmod ftdi_sio
followed by insmod ft245.ko in the directory you compiled the new driver.

Subject: RE: [SDR-IQ] problem with ft245 driver with Ubuntu 7.04 withkernel
Here is what I have found:
After I removed brltty from Ubuntu, and unplugged and replugged the
SDR-IQ, its lights did just what they are suppposed to do and the relay
On the other machine, recompiling after removing line 195 compiled fine.
My SDR-14 now works under Linux with Linrad on both of these computers,
one with Ubuntu Feisty and 2.6.20-16, and the other with Debian
184.108.40.206-0etch1 and 2.6.16.
The SDR-IQ is not recognized by Linrad under Linux on either of these
computers. On the older computer running Etch it had worked with
Linrad under Linux before, but I can't get it to work again even after
running 'make sdr14' from Linrad-02.35 from Leif SM5BSZ.
I am not sure why installing the new driver would stop the SDR-IQ from
being recognized by Linrad on the older machine, or why the SDR-14 now
works on both machines and the SDR-IQ on neither.
On Windows both the SDR-IQ and SDR-14 run fine.
Please let me know if you need more information, and Thanks for reading

Hope that helps, and

I'm trying to enable the spur reduction, but Enable AFC/Spur/Decode
only allows me to choose 0 or 1, not 2, so I guess the Windows
version of Linrad does not contain this feature; Is this correct?
Also, My LINUX version of Linrad does not recognize my SDR-IQ; has
this been fixed?
Roger: I'm happy to report I have successfully calibrated. The smart
noise blanker now works.

Linrad-02.39 can do calibration from recorded files, both .wav files
and files in Linrads own format.
This feature is intended to allow me to receive calibration files
hardwares in order to check that the routines work as intended.
There is now a new page about calibration in Linrad:
An ordinary function generator that produces a square wave can be
used for calibration on HF bands. The link has several calibration
files that you might download to try what happens when you
do different things.
(If your pulse generator is phase stable, the spectrum you will see
on the linrad screen will be sharp lines at the overtones of your
square wave - but that does not affect calibration.)
Linrad-02.39 also has an automatic spur cancellation routine that
can locate hundreds of spurs and place
