It's all about the Software

Hello, I am using SDRconsole v3.0.24 for a satellite operation at my university, and I want to receive a π/4DQPSK transmitter with a bandwidth of 30K㎐.
I have already confirmed that I can receive the signal in Wide-U mode and Filter24kHz, but the number of packets I can get is not enough because of the insufficient bandwidth.
Therefore, is it possible to increase the bandwidth from 24kHz?

I'm not familiar with this, so I apologize if there are any mistakes.

Don't think so at present. I suggest you add this in "Requests" rather than "General".

Simon (author) has not been active on here for several days as I think he has some building work going on, but when he comes back hopefully he will see your request and comment.

Not a mistake - add this as a request and I'll increase the wide SSB (somehow) to 48kHz.

Building work finished, will be back to coding as normal on Monday. Roof no longer leaky, bank account stinks!

Been there (bank account drained by builder). I feel your pain!

But worth it - with this new insulation I can't turn the heating low enough! And the roof doesn't leak.

The advantage of programming - I can keep going for many years to come, and pensions soon start paying out in 2022 / 2023.

Thanks for telling me!
I'll add it to my request as soon as possible．

Thank you for your consideration．

I am looking forward to the implementation!

FWIW I am exploring ways to have the SDR actively adapt to the characteristics of the filter the user requests for given modes. It ends up allowing absurdities such as an USB radio selection tuned to 7.2 MHz with a filter passband from 7.197 MHz to 7.1997 MHz. Do note that when it can adapt TOO much you can get absurd results that, in a pinch, do the job. The trick is figuring out how to change "everything" in a radio while it is running. (So far I have not extended that back towards the front end, yet. That's a someday job. What I can prove works I can pester far better SDR authors than me to add the feature I got working.)
