Title: Request for a wideband HF IQ recording for signal-detection project
Post by: Republic on November 10, 2026, 0345 UTC
Hello everyone,

I am an undergraduate student working on my final project on detecting and extracting HF signals from wideband recordings, and demodulating them if they are analog boardcast(SSB, AM and similar). I don’t have an HF antenna, so I can’t capture real signals myself, and simulated Claude data isn’t enough to test the work properly.

If any of you have a good HF antenna and a wideband SDR , could you share a raw IQ recording of up to about 10 MHz of bandwidth? Even a few minutes would help. If a full 10 MHz isn’t possible, a narrower recording such as 1–2 MHz would still be very useful.

It will be great help.Thank you very much for any help.
