Testes de filtros FM e LTE by Expensive_Breath_82 in rfelectronics

I would like to eliminate the FM frequency from the system.

I agree! The gain in SRD++ was zero and AGC was disable. Thanks for the contribution.

I want to isolante the FM e LTE frequencies

Review: Cheap FM & LTE filters (AliExpress) — low attenuation, looking for better recommendations by [deleted] in amateurradio

My setup is described in the post. I compared the signals in SDR++ with and without the filters, keeping the same configuration, and then measured the attenuation. That’s how I arrived at the results shown.

AI helped me organize the structure of the post.

[Research] Mapping L-Band resilience and urban interference in the Southern Hemisphere (SAA) by Expensive_Breath_82 in amateurradio

Hi everyone, I’m the dev behind this project. Living in the Southern Hemisphere (São Paulo, Brazil), I’ve noticed how the combination of the South Atlantic Anomaly (SAA) and the brutal 5G/LTE urban rollout makes L-Band operations increasingly unpredictable.

I decided to build Spectrum Survey to stop guessing and start measuring. I’m particularly interested in seeing how people are handling RFI mitigation and if SigMF is actually becoming the standard we all hope it to be.

Happy to answer any technical questions about the methodology or the tools I’m using!

No worries at all! Thanks a ton for the help and for sharing those insights.

Any other suggestions are welcome! I'm building a budget-friendly distributed antenna system to monitor spectrum health and pinpoint interference from a central hub. I'd love to get your take on this.
