Hello Gentlemen and happy new year.
I use SDR console with a transverter and Perseus as a band scope with point and click tuning. I did search the archives for what has previously been referred to as ‘Fixed Spectrum Mode’ which I think is what I want.
Maybe it would be best if I explain the scenario.
I want the Waterfall to always display between 144.080 and 144.400 and for this to be fixed. This would be optimal use with the DXSpots markers during a contest. When I click I do not want the waterfall display to move just the receive frequency. I am sure that this must be possible but I cannot find it. I am sorry for being so dumb!
Say I click on 144.185 I do not require this to be centred in the main waterfall, it should stay static at a fixed bandwidth. I hope that my explanation is clear.
I thought that I may be able to do this by setting the width of the horizontal slider at the bottom of the screen but I cannot fix it to specific lower and upper limits. I want to view around 450kHz and I am sampling with adequate BW on the Perseus. It seems to have been requested but I do not know if it has been implemented yet. If it has I missed it and cannot find out how to achieve it.
Regards

Hi group,Michel, Welcome to the group! It's undesirable to have very sharp filters, as they can introduce ringing and distort the signals being passed. Hence it's usually better to restrict the bandwidth by smooth filters rather than ones with sharp edges. Hence the difference. I'm sure others will give more reasons too. Simon may have an option to allow sharp filters, so that you can investigate the effects yourself.

Very basic question, sorry
michel soldevila
Hi group, The receiver bandwidth is set to 1MHz in SDR Console. I wonder why the "useful" bandwidth seen in the waterfall display is only about 750 kHz ... Michel, F1GOC

Re: Dependency on Intel DLLs
OpenCL is optionally used by Console, maybe that’s why.
There’s no need for Console to run on a FPGA – it needs some CPU and DirectX graphics. Things like the Intel 12th / 13th / 14th generation run programs like Console / SDR# etc. with ease. Console (and SDR#) is a very, very efficiently coded program.

Bitmap Display: How to change receiving frequency
Nils Schiffhauer
Hi, all - I just found an easy way to change the receiving frequency with the "Bitmap Display" is still kept open.
It works with the "Frequency Database", and it works just fine. I added this procedure to my blog entry with two explaining screenshots: https://dk8ok.org/2022/01/02/sdrc-new-bitmap-display-helps-to-raise-dx/ 73 Nils, DK8OK -- dk8ok.org

This looks really useful, not just for HF propogation analysis, but also activity monitoring at higher frequencies.
Thanks to Simon for yet another addition to the all ready excellent SDRC and to Nils for the heads up. HNY - Alistair (M5ASF)

One thing,I'm 73 now, and still writing code. I half-retired some time back, and can now concentrate on the bits which interest me, or the very few serious issues with my own software. Fortunately the weather satellites my software supports are gradually retiring, and there are others supporting the newer satellites (although not needing to use that as a means of living, as I did, but being supported by a "day job"). I do try and help others, but have little patience with those who ask the same questions again and again, and don't appear either to search for or to read the material to which they have been pointed. Mind you, I probably appear to do the same when Linux is mentioned - but fortunately using the Raspberry Pi extensively has ameliorated that to a degree!

Hm, maybe I can convert the rtlsdr source I have to
handle extio files. That might keep me off the street a few days.
OTOH it would be a more fun challenge to skip the extra dll and
include that code into a sourcexxx.dll. Then you'll be able to
Simonize (ouch) work I kludge into something in your style and
more trouble free.

Ah,
But I’m hoping to be on top of my game until I’m 70 – very few guys writing serious code at that age. Long term I’ll be happy to bat along until I’m 75, then retire to Spain (maybe sooner).

I see that it would be nice to play with but is not very practical and requires a lot of effort from me. There’s no API for the RX888, just raw ADC data and ‘good luck to the programmer’.
