Hello everyone,
I am an undergraduate student working on my final project on detecting and extracting HF signals from wideband recordings, and demodulating them where they are analog (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. A short note on the center frequency, sample rate, receiver and antenna would be a great 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. Hoping for a favorable response.Thank you very much for any help.
