The setup is, there are persistent signal spikes across most HF bands, very loud, up to S7 or so, that don't appear to be exactly "local" in nature. These seem to be evident at all hours of the day and night.
Here's a video recording of my local receiver panadaptor coupled with a remote receiver that follows the local tuning, and the audio from the remote receiver, which is over 6 miles away.
There is some lag between the local tuning and the remote receiver tuning/audio response. Any ideas what these signals might be? https://youtu.be/zyOkDtgweUs
