Re: different type of radio receivers
Mike
So do the mod to do an IF tap on the radio, and feed the signal to the SDRIQ. Then you can use better software to see the signals.
Friendly Regards,
Mike

Hi,
In theory I guess it's possible but in practice I am closely tied with Rfspace so cannot support other commercial solutions at the moment.
Sorry, I see you posted in the Winrad forum, that's maybe your best shot for now.

Full Screen
Simon HB9DRV <simon@...>
Hi,
I find I use full screen a lot with build 471 / 472 it's in the top right (472 fixes a bug with full screen support).
Try it!

About a minute, but of course much less is enough, just to see the carriers. In spectral view only a couple of seconds is needed.

I just meant a quick glance with deep zoom on a certain fq to show the strongest carrier peaks, either as spectral view or waterfall or both as in Spectravue, please see a separate attachment at the end of this message of sample screenshot showing (mostly) Asian signals here just now on 1143 kHz. I tried to upload a video, but the file was too big. It is slow, but not too slow!

Spectravue generated files - UTC displayed correctly? (Build 472)
Mark \(G4PCS\) <g4pcs@...>
Hi Simon, I notice I get an hour discrepancy in the time displayed whilst playing files that were recorded by Spectravue during British Summer Time. For example, playing a particular file in Spectravue displays the time as (24/05/10) 14:50z, and the same point in the same file is displayed in SDR-Console as (24/05/10) 15:50z. I'm pretty certain the Spectravue time is correct; I wonder if it stores a UTC offset in the file header separately to the time, that isn't picked up by the console? Dotting the i's and crossing the t's, the console is damn good :D Regards, Mark EI3KD / G4PCS |

hello i have a question, is it possible to make the software work with an old winradio receiver i have a 1000i i bought many years ago new.
and it works well,but i think the original software is not very good. its slow and the waterfall part is not real time,and thats a pain. so just wondering if it was possible. |

Re: New release
Leif Asbrink
Hi Thomas, Mauno and all,
That is what you would do when using Linrad in coherent mode to selectAlso tried the new IQ analyser. That is something which lots of peopleIs it not possible to use this better resolution in live listening? one or another carrier as the phase reference: http://www.sm5bsz.com/lir/am640/am640.htm http://www.sm5bsz.com/linuxdsp/usage/kari/kari.htm The delay from antenna to loudspeaker becomes very long since the audio is derived from a backwards transform of a very long transform. 30 milliHz resolution requires 15 mHz spacing between bins. Data spanning 1/0.015 seconds=66 seconds must be stored before the FFT process can be started. If your sampling is a 1 MHz you would need 4*2*1000000*66 = 528 megabytes of raw data as the input to the second fft in linrad. Twice as much is needed to store the output. Buffers have to be allocated in sizes that are powers of two so 1 MHz is not possible. I have made this tool available long ago but nobody has ever reported any interest so I have not made any attempt to improve it. It is obvious that one can down-sample to a modest sampling rate like 12 kHz before running the process. Then the need for memory and CPU power would be very small and one could make buffers span much more time. Maybe Simon will become interested in developing a more userfriendly user interface for something like this. The method should be very powerful for MW DXers who should be able to find situations where the improvement is much bigger than in the test cases I have uploaded. 73 Leif / SM5BSZ |

Re: Waterfall colour scaling (build 472) - a question.
Mark \(G4PCS\) <g4pcs@...>
Hi Simon, screenshot (hopefully) attached. There's a not-too-strong ssb signal in the centre of the waterfall (and lots of birdies :( ), and I hope you can see the dark banding across the bandwidth? There's some latency between the signal and the "visual modulation", like some sort of AGC effect.

Hi,
Yes but:

Waterfall colour scaling (build 472) - a question.
Mark \(G4PCS\) <g4pcs@...>
Hi Simon, display setup: Scope range set to manual (high = -60dB, low = -130dB). Waterfall "Auto" deselected. what I see: Watching a quiet band, bandwidth set to 150kHz, I've set the above numbers to show me some noise in the waterfall... not a lot, but something nice and "smooth". If a narrowband signal then appears anywhere in that bandwidth I (obviously) see the signal but I also see the noise floor drop, i.e. the rest of the band gets "darker". This has the (very undesireable) visual effect that any signal appearing in the bandwidth of the receiver "modulates" the noise. I don't really understand why this is happening when I have everything that seems to be relevant set to "manual". It's not something I see with (e.g.) Spectravue. Any ideas? Thanks, Mark EI3KD / G4PCS |
