The website you're viewing is a v2.0 upgrade of the original, which had built up a considerable legacy of dusty truths over its first two decades of life.
The old content got re-organized, re-journaled, and brought up to a "modern" spec. For example, the Receiver Setup Manual is actually useful.
You'll also find lots of information, preserved in amber here, which is either (a) outdated, (b) impractical, (c) irrelevant ... or, more likely, some combination thereof.
This station has a history ... and I hope it will provide you with some entertainment value.
