choosing subdev in B210 #uhd #ettusb210

mdolecki@...
 

Hi

Is it possible to change subdev param in SDR console -> Radio Definitions for USRP B210? By default it useing A:A setting, but I need to set A:B. How to do it?

Additional question. Is it possible to make multiply configurations for the same device in Radio Definitions? When I choose Search Ettus Research (all models) it always replace existing configuration, even if I choose Add. I'd like to have multiply configurations for different tasks but all for the same board.

Check if Nvidia Cuda is activated in the settings.

I am looking for more ideas to track this down.
I have tried running the server software on 4 machines now and only one of them has the problem.  It is a MSI K9N MS7260, with an AMD 64 X2 5600+ processor and 4GB of RAM, with Win10 64bit.  I have the latest FunCube device.
When used as a server with the V3 software it sends bursts of data to the local network (LAN), see attachment. This behaviour is present both on wireless and 100BaseT Ethernet.  The V2 server does not exhibit this behaviour.
I have experimented with other machines running win10 and win 7, these work fine. The Adaptor, on the Task Manager performance page, shows a steady 1MB/s

Hi David,

The K9N machine will support 1000BaseT but the router I did the testing with is limited 100BaseT.  The machines I tested with were a ga-m52l-s3p with an AMD 64 X2 6000+ running win 7, this also is limited to100BaseT, An Acer with Intel Atom N270 cpu 1.6GHz, running Win 10 32 bit and a new Lenovo running win 10(my sons machine so that all I know).

All machines except the K9N run the server with the same 1MB/s network rate.  The K9N also behaves the same with a wireless connection via the latest BT router.

Paul

============================================

Paul,

Are they all AMD machines? Do they have 100 Mbps or 1 Gbps cards?

Lime will have TX support enabled in Q3 with luck.

We are all awaiting this version. Will the LimeUSB be transmitting, or is there still some work to be done on it?

Conrad, I believe I'm looking for the same feature.
Using the Satellite tracking feature in SDR-Console (for say FO-29 or CAS-4B) the doppler is adjusted for the SDR downlink and you can configure the software to also correct for doppler shift on your external transmitter. But as you said the key missing feature is for the transmitter frequency to track the downlink (SDR) frequency automatically as you tune around. Right now you must find a signal on the satellite then manually adjust the transmitter frequency every time. It is possible to work stations this way but more difficult and cumbersome. I haven't found a solution yet.

I already have this functionality with my FT-847 controlled by HRD 5.24 (which Simon created). First step when working a satellite is to transmit and tune the uplink frequency until you hear yourself on the downlink, then you can tune around and the Tx/Rx frequencies stay aligned. It is fantastic, almost like working HF. I tried running HRD 5.24 connected to SDR-Console as a virtual TS-2000 but there was lag between the two programs making it unusable, or at least not an improvement.

I believe Simon is working on this. There is this note on the Tracking page of the SDR-Satellites website: "To Do: The external radio support will be extended to provide full tracking between transmit (radio) and receive (SDR) frequency, as part of this a more advanced display will be written. This is planned for 2018." I'm very excited for SDR-Console to add this functionality in a future release so I can finally move away from the old HRD program.


Re: Sat tracking #satellites

Conrad
 

Yes that's my dilemma. It seems like an easy jump from where we are now. I have tried HRD but I much prefer SDR Console as I can see the signals and select the ones that I want to try to connect with. I guess that since you see the problem I am doing things correctly for this stage of development. I hope that sometime in the future the manual tuning aspect can be upgraded to a point and click system so that the SDR and the external transmitter will both track the particular station that has been selected. Thanks for your thoughts and thanks to Simon for the wonderful piece of software.

Hi Simon et al ,
I once had a similar problem with suspected USB power, not enough, and solved it easily: just used a cable with dual USB plugs, one only for power and the other a normal one, (is a standard cable, easy to find on the market,  but I do not know how to name it ...) so that I have two USB ports powering the device. Other time I used a modified USB splice cable, I modified it so that power is taken by external Power Pack and signals are from the laptop USB port. This worked fine also. Simple hint that may solve similar doubt, and similar situations, the second very useful with small android devices.
Hope this may help somebody, 73 44 de Augusto I2JJR HB9TZA (5R8JR)

No errors in the logfile. When USB radios work like this I often suspect USB power issues. I don’t have the SDR-14 so testing is not easy.

I have attached a log file :)  Hopefully the attachment works here on groups.  In that instance, the SDR-14 receiver is started, it quits running after a few seconds.  I press stop, then start and the receiver runs a few seconds and quits again.     The SDR-14 has a front panel LED indicator labelled "USB" and another labelled "CAP".  Per the manual USB indicates data transfer and CAP indicates RF to digital conversion is taking place.  In the resting state, the USB led is on, the CAP led off.  During receiver operation the USB led flashes rapidly and CAP is on steady.  When the receiver quits operating, the USB led will flash at about a 2Hz rate for a few seconds and the CAP led goes off. The USB led then remains on.

I tried also thru a USB hub as Chris suggested.  I tried a powered USB hub, but in that case the audio stutters while the receiver is running, and it quits receiving after a few seconds as with the direct connection to the computer.  I'll dig thru some parts boxes and try to find some other USB hubs to try.

Thank you,

Trevor

Hi,

Just for reference I have an SDR-14 and have tested it on the latest kit over the weekend without any issues. Looks like a hardware issue rather than software.

Simon, if you get stuck and need to borrow my SDR-14 for a few days, let me know, I'm more than happy to help.

Keep up the good work, looking forward to V3's release, donations for dog food pending :-)

Cheers,

Dave.S.

Thanks very much.  The SDR-14 is powered with an external supply, though I'd have to check the schematic to see if the USB5V powers any of the internals as well.  I still have to try out some other USB hubs and perhaps another computer too and see what happens.  If it would be helpful, I could also try to do find a USB debug s/w and record what's going on with the port.
Cheers,

Hi Doug,  

If the AGC is on then check the menu bar with the "Home" tab selected.  For my RF Space SDR-IQ the fixed RF and IF gain settings show up there.  (2 controls over from the start/stop control.  Picture included.   What shows up in that space might be dependent on what receiver you are using.
