Received Airspy HF+ Discovery from local flea market for my SDR collection. The gold standard for DXing!

The problem of the overlapping tx times was solved by @sdrsharp with 3 MHz bw and 6 spectrum slices, 48 kHz bw each, with scheduled recordings. 50-60% CPU load on an old i3, 4GB, w/o separate GPU, when all SDR# windows are minimized. Recorded IQ files were small, ~100 MB each.

This is an unwise statement that can only make people confused about what LLMs can or cannot do. Let me tell you something: Math is NOT about solving this kind of ad hoc optimization problems. Yeah, by scraping available data and then clustering it, LLMs can sometimes solve some…
