K4 and SDR-Console

Fred
 

Anyone using the Elecraft K4 with SDR-Consloe?

I'm have a small problem.
When I have SDR-Console running then I start the K4 up it puts the K4 into transmit for a few seconds.
When I start the K4 first then start SDR-Console this doesn't happen.

Any have any thoughts on why this happens?
And yes I know one answer is "just don't start SDR-Console first".

I am using SDRPlay RSP2Pro.

Thanks 73

That would be my understanding also, and easy to test in SpectraVue.

I've just played back a NetSDR file in Continuum mode, 1300kHz span of the MW band, using 2048 point FFT and 2097152 point FFTs.

Except that the 2048 point playback zips by very quickly (unsurprisingly), it jitters around -32 dBm, while the 2097152 point playback is more sedate in speed, and with very little change in the -32 dBm value, again unsurprisingly.

The "jitter" is presumably real, as the power level of individual signals in the night-time MW band is constantly changing.

If the commenting in SpectraVue's code is anything like what was in Moe's SDR14xApp, and CuteSDR,  he probably tells you what he's doing right there.   Finding it might be another thing.

Re: Continuum mode

jdow
 

Figure one signal is present, a unit gain (0 dBfs) sinewave. Without shaping it will appear in one or two bins ideally. You take the power level for all bins within the bandwidth Y and sum their power, not voltage, of course. It's independent of the X bandwidth. Scaling would be the same as you use for the spectrum display.

Or take the FFT array of values, multiply each cell by your calculated IF filter shape, pick a bundle of values around the center of the filter to get a nice power of two bin count, take reverse FFT, pseudo power = I^2 + Q^2, Nominally ir should have scaling to make that come out as 0 dBfs for that single sinewave signal. Then the real world should sort of fall out of what you have with no further work. (Yes, I am fixated on I^2 + Q^2 pseudo power.)

Re: Continuum mode

jdow
 

Heh heh - processing in the frequency domain makes a lot of this easy. The chief issue is the current FFT resolution compared the bandwidth you want. The "cheap, quick, and dirty" solution is sum the power in all the bins within the bandwidth you want. I suspect using some shaping on that would add a decimal place to the accuracy as well as more processing demand on the system.

Now, if you use receivers as the filtering mechanism running a reverse FFT on that bandwidth (and a little bit more which will be super close to zero power and gives a power of two number of FFT steps) gives you time domain I and Q signals. And, I wish SDRC did this so its S in its SINAD fiddling would not be spoofable, square I, square Q, sum them together, and take 10 log that power equivalent. That gives the continuum measurement as well as a very good S for calculating SINAD ratios. (As Simon curls up in a corner screaming "I didn't read that! I don't wanna do it!")

(Snarky today Joanne? Yeah, just had the telephone guy come to deal with noisy phone lines when it gets windy. It was still air. So, in another half hour the internet vanishes here as the afternoon winds kick up. This time it's war. A couple days ago the noise made a telephone consult with my doctor a miserable series of "say again" and CRACKLE! CRACKLE! CRACKLE!)

This is because with the now available very broad band SDR's (e.g. RX888 etc.) it might be impractical or undesirable to measure over the entire sampled BW due to spurious signals, unwanted signals or other limitations.
The cursor reading has earlier proven to be a very practical feature when using Continuum Mode.
I hope these are feasible functions to implement.

Not at all.

Good answer Curt.  I might have been the only one confused.

Thank you Simon. A small thing, on the download page the small blue cloud
symbols both link to the October 2021 version, the textual links are correct
and point to the appropriate version.

Hi,

 

At the moment it’s a 2 : 1 (rectangular) projection, even when zooming. When I have time I’ll use more screen when zooming.

your map/software is very much appreciated Simon......my one question , is how can I make the map fill my screen? On my monitor, the right 2-3 inches of my monitor is empty......the "edge" of the software box goes to the edge of the monitor, but the map stops short of full width.....

Better zooming quality and custom 7, 14 segment fonts for the clock display. Also lots of minor tweaks and twiddles.
