Our current SDR online list: https://list.websdr.fun Paul has done a good job to list them (almost) all. The old ones keep working for some time, but links will be stopped at some point.

Synchronous AM Demodulator

My first thought for new features in PhantomSDR+ would be a synchronous AM demodulator. As one who does a lot of listening to mediumwave and HF broadcasters, often under conditions of QSB / weak signals, synchronous works better. I am certain that a fair number of SWLs and MW DXers would appreciate it.

Here is a screenshot taken while receiving the talk show "Coast to Coast AM" on station WHAS. It seems to be a quiet evening on the NY4Q PhantomSDR site, with very few static crashes from lightning.

These is a BCB filter on that receiver too. I'm amazed you saw a signal.
