This is a new HFU feature I am working on. Not quite done yet, but far enough along I think for some more widespread testing.
It's a real time schedule of SWBC transmissions currently on the air. You can see all of the transmissions, as well as narrow down your results by language, country, target, frequency range or bands. You can also look for transmissions at a specific time, vs those currently on the air.
Links to directly tune in the stations (with frequency and mode set) on several KiwiSDRs are provided. There's even a field so you can add your own favorite KiwiSDR URLs to your custom list.
If you encounter any bugs or have suggestions for additions/improvements, let me know.
