Just to reinforce what Finndx said, indeed SRCP for StationList and MPX would make SDRC the ultimate software for FMDX'ers.

Re: USRP B2xx bandwidth

Andrew,

 

Thanks for the feedback. The issue with 56mHz is, I believe in the UHD.dll code. As for bandwidth list – sure, let me play with this but 28MHz is about the maximum you’ll see without shuddering. I’ve made a note…

Simon --

Tried the new SDRSourceEttus.dll with SDR-Radio V3, 64-bit, 2018-04-30_2059.  It successfully displays rates up to 56MHz now.  While 28MHz works smoothly, I find that the 56MHz setting has substantial "shuddering" in the audio (like the USB3 bus isn't keeping up), but it at least detects and negotiates.

Is there any way to select clock rates/bandwidths between 28 and 56MHz (ie, 40 or 50MHz), or are we stuck with 1/(2^n) fractions of the 56MHz max rate on the Bxx?  Seeing as the old DLL maxed out at 16MHz (and 1/(2^n) fractions thereof), I thought it might be possible, but haven't explored the UHD driver sufficiently yet.

I've attached a screenshot of the new dialog and a logfile in case it helps.

Hello Simon (and fellow enthusiasts) --

After unpacking my shiny new USRP B205mini and setting it up under Windows
10, I was delighted to find it discovered readily by SDR-Console v3.

Currently, however, there appears to be no way to select an IF bandwidth
wider than 16MHz in the radio selection dialog. The "Ettus Research" page
on sdr-radio.com has the following note under the To-Do section:

Apply the UHD update (when available) to support up to 61MHz bandwidth from
the B200.

I'm simply curious if this update is expected soon. Does the current UHD
release have the necessary components or is there something needed from
Ettus? The program and device work together flawlessly otherwise over USB3
(maxing out on USB2 at 8MHz before stuttering).

Thanks!

Ok, so it was MPX connection method that failed. Also, It is worth considering adding pure data stream by Bit protocol or ASCII G protocol for RDS Spy use.

Mike, if you haven't read about my tests yet - you can run RDS Spy in conjunction with SDRC v3 already ... well, to some extent:

Re: Manual Notch

Leif Asbrink
 

Hello Simon,

this filter is by far not sharp enough. You would
have to allow something like 32768 for the filter length
with a bandwidth of 17 or 18 Hz. (Maybe resample to a
lower frequency first.)

73

Leif

One quick comment - you can create very sharp bandpass filters with SDR
Console, for example see below (filter length is at the max). This will ring
though.



If / when I get time I'll add a complex DX window with LPF / HPF / Notch /
whatever, but for now I'm rather busy elsewhere.

Thank you, Leif, for taking the time, firstly to examine the recording, but
also to document the various ways that you can tackle the analysis with your
video.

Linrad is a very powerful collection of tools. Of course, that implies a
very steep learning curve, and it is daunting to a new user. But, if we want
the results we have to study, and I have promised myself to spend some time
over the poorer summer propagation period in learning how the software works
with a few older recordings.



Naturally, I am also encouraging Simon to bring his manual notches towards
the front of the Console development queue. Although the Console has a more
'general' user-base than we beacon-hunters, the availability of a
point-and-click GUI is attractive to all users.



One question to you both:



Various SDR-softwares Have different ways of noting frequency data. Leif's
video demonstrates this, clearly. As accurate frequency information can be
very important in some applications, is there a way of translating the
frequencies as we move between analysis packages?



Thanks, again to both of you for all your development and patient
explanations.



Best Wishes

David, GM8XBZ

Re: Manual Notch

Hi Simon,

Thank you for the advice. I had already tried filters of 30Hz and narrower, but did not have much success. I will try again following your example, setting by setting to make sure.
One of the issues with very narrow filters is that the Receiver pane auto-scales to such an extent that the display becomes unhelpful. Swings and roundabouts, I guess. (It was when I created a new narrow filter that I found the GUI-error when using CW-L. The frequency is displayed incorrectly, and the filter edge indicator lines are mis-placed).


I know you are busy, and SDR-Console is not the way you earn Millie's food. I still enjoy the software, and find it a great match to the HF+, so I can wait. But that DX window looks _very_ attractive.

Best Wishes
David, GM8XBZ

To find the reason i:
- connect to the spyserver via Wifi network (so no ethernet cable)
- attached a battery to supply the the raspberry and the airspy hf+ both with 5v enough power
- put the raspberry completely into a metal case

Nothing helped... There are just 2 cables connected, power via battery and airspyhf+ to arduino.

I tried to find a information/help in the airspy-group, but the only thing i heard was use Sdr#. From my perspective, it could be interference out of the raspberry usb port or something is different in the linux drivers and spyserver.. I did not test with real small signals, im just comaring the noise levels.B Do you have an idea where to look at or what this strange different could be?

As the family 'IT' troubleshooter, get called to far fewer 'incidents' than with previous versions, and actually any problems are usually due to a specific prog or app, not the OS itself.
