I've seen this behaviour as well, though not after retuning. Swap
seems to occur at startup. Out of 20 starts I'll see at least one A/B
channel reversal. I do retune the DDC frequently while running, and
that does not seem to be related.

Tides,
Following the steps on Balint's page got everything done. It turned out he was
missing one detail on there about installing all the software to the HDSDR
directory. Doing that fixed the problems I was having immediately.
Caveat to that is, most people probably don't have HDSDR installed before
running his package - I did because I had already tried running it and doing
other things so many times. So, I just ran the package again and pointed it to
the directory - for those who do NOT have HDSDR already installed I would
install it seperately then run Balint's package and point it to the HDSDR
directory... or, you could just run the package twice, the second timing
pointing to the HDSDR directory.
As far as the N210, I'm really not sure how that would work out. All the
software I've seen is for USB interfaces - what exactly is the error.issue
you're having?

Hi Dan,
I'm trying to do the same thing (run HDSDR on windows) with my USRP N210. Could
you share the installation step that works for you? Eventhough, there are
differences between USRP B200 & N210 (N210 use Gbit ethernet interfaces to
connect to the computer).
I have try several times, & had an error message each time i run HDSDR.
Thanks

I know I'm replying to my own message here, but I wanted to add some more
detail to what I last wrote. I've attached a screenshot of the error that I
keep getting when using HDSDR. It states "Load ExtIO DLL failed: %1 is not a
valid Win32 application." This happens when I try to click ExtIO in HDSDR (see
this site for details - I've followed all the steps given there). Aparently
this is a common problem with 64 bit users... does anyone know a workaround???
In response to Marcus - Using the system with HDSDR is just one small
application I'm using the B200 for - I'm using the system with great success in
Linux and it has been wonderful for GSM as well as a VHF radio station. I know
the problem I'm experiencing is with the ExtIO plug-in and I didn't know any
other message board to turn to. I figured this is a general troubleshooting
message list and a good way to get a hold of Balint - if there is a better
group out there, please let me know!
I am trying to write a good guide for all the people out there that are not
researches and the like - Since I've been through the hard stuff, why not write
it all up so it becomes easy stuff and people can learn how to use Ettus
products even faster :)
All the best,

Subject: [USRP-users] B200 Step by Step on Windows
All,
I would really like to get a straightforward guide written for my setup (and
hopefully other setups).
I am currently running Windows 7 Pro on a Dell M4800. I am trying to get this
B200 working with some kind of waterfall type software (I would like to be able
to see the spectrum and move around through it).
I have installed an overwhelming amount of software trying to get this thing to
work with no real success so far.
I can navigate to the C:\Program Files (x86)\UHD\lib\uhd\examples folder and
run some of the programs there from the command prompt. The computer sees and
communicates with the B200, so now, how do I get it to work with something like
HDSDR or SDR-RADIO???
Thanks,
- Dan

Content-Type: text/plain; charset="us-ascii"
Hey guys,
Just wanted to let you know I am almost done with the CAD drawings for cutting
out the end caps on the Hammond 1455L1601 metal enclosure (Hammond Schematics
are here). I am able and willing to do the machining for a small price if you
so desire. I have this case myself and it looks great. Let m/e know if you are
interested and I'll give you more details.
For you Ettus employees, somebody mentioned an enclosure coming out a while
back - I don't know if you have made any progress on that, but if you are
interested in me doing some mass production or even some customized cases,
please feel free to contact me directly.
Sincerely,
- Dan

Hi Dan,
I've already install UHD & HDSDR, and i've already test using
uhd_find_devices.exe & uhd_usrp_probe.exe and it's working fine, the
computer detect the USRP. When i start to install ExtIO_USRP+FCD +
BorIP-1.1.1_Setup, and it comes to zadig installation step, i cannot find
the USRP N210 in the list, so i skip the zadig installation process.
And when i start to run the HDSDR, it shows error message (please see
attached file). Any suggestion to resolve this problem?
Thanks

Subject: [USRP-users] WBX receiver issue
Message-ID: <[email protected]>
Content-Type: text/plain; charset="utf-8"
Hi al,
I was receiving a -50 dBm signal with WBX receiver. After some time, the signal
spectrum disappeared from the frequency scope, all I could see was only noise.
I did some measurement and found the grand daughterboard works well (measured
voltages were according to the spec sheet). But in the main receiver part I
could measure voltages of 6V and 3.3V at both U306, U308 (ADP3336). The
voltages at attenuator (U302), LNA (U313) and other components are only around
0.03V. Does it mean the receiver part is burned or only the LNA (MGA82563) is
destroyed?
regards,
Saran

I'm going to be in Krakow on Friday and Saturday. If anyone is interested
in getting together to discuss USRPs or GNU Radio over food and/or drinks,
send me an email.
I'm also giving a talk on Friday morning at AGH in Krakow in building D6
