Walter, that first link you've kindly provided is this same thread, just a page back.
I'm still waiting for Ezzer to comment on a question I asked about REIN myself, also, the 'experts' I know involved with REIN, and our in-house guideline documents all say you will only detect REIN at 612Khz on the MW scale. Other interferences at different frequencies found on bit-loading graphs will not be associated with REIN apparently.
