Mike, in radar as in QRP, there is no free lunch.
Rest assured any broad spectrum signal can be found. For one thing it
inevitably brings up the noise floor and that can be detected. Good
receivers like the K2, could be helpful in noting such effects from new
radars or BPL use in an area.
Keep an eye on this one. Undetectable Radar! The inventor says it sounds like
static on a receiver.
