Re: 3D waterfall

Hello everybody
Taking this opportunity, I shot a video of what the experimental Russian HF hopping system looks like in the experimental 3D function from Simon. Sorry for the pun :)
   In this case, these are 8ms tones that are pseudo-randomly distributed over a 100 kHz bandwidth. Parcels do not overlap in time.
Thanks to Simon for the tool, and I hope for its further development.

Danila.

Probably they do match in terms of power per pixel. The number of pixels wide makes a difference in levels.

I find it interesting, and played with it for awhile.  Wasn't sure where in the band, or band width, was showing, but comparisons with the waterfall soon rectified that.
One thing that might help, the background noise (noise floor) does not match that in the waterfall it seems.  I need to adjust the waterfall to see the noise a bit to help in locating signals on the 3D - maybe some freq numbers, or other locating device could be added?  And/or a slide to adjust the background noise level in the 3D separate from the waterfall one? Using the "Auto" button on the left of main panel makes the 3D have zero background to help see the weak signals, so the suggested slide or a bit more gain in the base 3D setting may be of assistance.
Looks like a nifty addition, not sure if I will use it a lot, but interesting to play with.
Thanks for the toy Simon!

Hi Everett,

Can you please explain what is "improved" (asking for a friend, as I already have one of your LZ1AQ amps built with 2SC5551s)?

Thanks,

Hi Simon et al,

 

Has anyone been able to get SDR Console to talk to an SDRPlay over an ethernet connection? SDRPlay provide a raspberry pi image which can run as a host, and expose the SDR over an ethernet connection.

 

There’s an ExtIO DLL available for HDSDR, but SDR Console is a much better piece of software than HDSDR in my opinion, and I’d prefer to use it if possible.

 

If I’ve missed something obvious, and SDR Console will already talk to ExtIO DLLs, do let me know, and I’ll get that imported instead!

Re: Editing Favorites

Easiest way is to recall the Favourite (7.0 to 7.3).

See the semi transparent bar at the bottom of the waterfall. The translucent part shows the current span of the waterfall display. Just take the left hand edge of the semi-transparent bar, left-click and drag it up to 7.125, then click "Update" top left of the screen in the Favourites strip. you will see a confirmation box come up with the new span. Click "OK". Job done.

See attached screengrab.

Hope it helps.

Re: Editing Favorites

Curt Faulk
 

Dominic, I'm not in front of the software right now but I think if you dial in the view that you want and then add that as a favorite it will save the spectrum that you are viewing at the time. You can then delete any others that are near duplicates that you want. I'm recalling this from memory so you might give this a try and see if it works..


Re: SNR meter, bandwidth and gain adjustment for transverters

jdow
 

The description seemed unclear to me. I "think" it is a tool for pulsars. It more or less shows a spectrum plot with the spectra taken at specific time intervals relative to the pulsar rate and lined up in a waterfall. Does that sound right? That sounds VERY useful. I learned something. Thanks.

(And I played with the trig. At least for AM summing the spectral elements power does give back the known power that went into generating the waveform. I have to do one more expansion to settle my mind. I still think I^2+Q^2 on the IF filter output is the simple method in most SDRs.)

Editing Favorites

Dominic Dambro
 

I'm an avid SWLer and my main area of interest is the amateur bands. Is there a way to edit my favorites to fine-tune the amateur bands into voice-only? For example, the 40 meter amateur band favorite brings up the entire sprectrum of 7.0 to 7.3 MHz. I just want it to display a more spread out 7.125 to 7.3 MHz.

Thanks,
Dominic

RSPDuo and SDRC

Hello SDR-Console,

I just got an SDRPlay RSPDuo, or is it called RSP2 ? Anyway, I was controlling it with SDRC, loving it ...and wondered if I could also activate the Diversity mode?
I have two different antennas connected, through protection to the RSP2' two antenna jacks.
Using their own SDR-Uno, I can activate Diversity and pipe it to WSJTx.


However I am having issues with SDR-Uno. And mainly, I have tons of memory data stored in my favorite SDRC so want to keep using that.

[Edited Message Follows]
[Reason: Initial send occurred for seemingly no reason.]

Joanne,

I probably misspoke at some point if/when I said BCFM carrier is always the greatest power anywhee in teh passband, so I retract any such statement.

However, that statement does hold true for BCAM, so I've captured a video of SDRC's S-meter reporting on a BCAM station:

https://drive.google.com/file/d/1Egb4DyIxXtZNP6rNNKg5PLfQzFTH_7zI/view?usp=sharing

Several key observations:

1) The carrier is very steady.
2) The modulation varies greatly.
3) the passband is intentionally varied between 2.5k and 12k.
4) The S-meter never varies at all (at least not more than .1dB in any direction).
5) The S-meter is reporting ONLY the peak signal detected anywhere in the passband, nothing more and nothing less.

So tell me where Simon gets it wrong.

Nevermind, that's a loaded question...Simon gets it right.

I'm done here,
Mark
