scary indeed. I'd be scared trying to think if a "better way" to visualize the data. 500 MHz on a UHD screen with ten full width spectrum spans is still more than 12.5 kHz per pixel.

I think I'd try for 8 screen widths and discard some cruft off the edges to use a 32768 FFT for full width visualization and then mixers and decimators to get regions that need higher resolution. Even with "many" such spectrum chunks it might use less processor and still give full information and flexibility.

That said, a display system that could display say a single pixel for each bin of a 536,870,912 bin FFT would be......... impressive. By then the resolution of the human eye limits the ability to grasp information.

i do the finetuning in the receive panel (not receiver pane but the receive dsp panel ... receive "dsp"box ... and use the if display

for only ONE receiver thats good enough (and saves a bit cpu load)

but i try to AVOID the center!! (0hz spot) ... thats why i asked simon for a zoomfuction that does NOT shift also the lo to move receive filter to the center

Hi Alex,

It's also possible to use the receiver pane. Which by default shows one receiver, but can have 8 receivers side by side. I'm always using it as a little window on the second screen for fine tuning ;)

Thanks for responding.   I tried your suggestion and it does center the receive frequency....thanks for letting me know that this is a workable option to my question. Best....

Hi,

The API options are to select a specific card or the 'best' card. The widest FFT I've encountered is 100MHz, with x8 resolution it's been close to 1 billion bins / second. The GTX 1070 worked but it was getting close.

At some stage in 2020 I expect to interface with a VHF / UHF SDR which delivers 500MHz of bandwidth. Scary stuff, I doubt that my motherboard will handle the data, let alone FFT.

Perhaps if second best is good enough it should be used leaving the other one for some other high powered calculations. It probably also has a place in regression testing to have a "weak" card you can select for testing.

So, It would be nice to choose which Nvidia GPU to use if multiple GPUs are present. While this is niche setup it would be a nice feature to have.
I figure this wouldn't be very difficult to do hopefully.

Re: V3 SDR Server bandwidth question #sdrserver #rtl

Put another way, Simon why are the RTLs limited to a bandwidth of 300 kHz in TCP mode using the server?

Is this difference deliberate?

I recall in V2 server the bandwidths for both TCP and USB were identical and went above 2,000 kHz, mind you could only go that high over the LAN.

Hi David,

First thing to check is in the select radio dialog, do you have for example,  "Line (2-FUNCube Dongle V2.0  )" selected from the dropdown menu in the Soundcard selection?

If not, then there is your problem, in all likelihood.

Re: SDR Radio v3 dies after a few seconds of operation

Hi Simon,
Better late! After Tom's suggestion I upped the max virtual memory to half of what I had left on this drive, total about now 50 G max with 16 min and all seems to be working fine since I did that. Limping along perhaps but seems to be getting ok decodes ft8 without hiccups. Solid after multiple restarts so we'll see. Only problem, I can't tell what I'm missing if any! Tnx for the link tho, good stuff. And tnx Tom and others for the suggestions!
