A long time ago, in a galaxy far away, Dwight and I were messing around one weekend after checking the main radio out on the regular frequencies, so we went up to 11 meters and started listening while pointed at various points of the compass. We picked up a strong signal about 61.5 degrees east of north and called out to him. It did not take him long to start boasting about his linear amp, since Dwight had said we must be able to communicate because of skip. The guy remarked that we were quite clear also, so we told him we had a 10KW Collins driving a log-periodic antenna array on a rotating tower. He then asked if we were 'afraid of the Feds', so Dwight keyed 'We are the feds.' Complete silence for about a minute or so, then very faintly some voices saying in effect "We hope you guys catch him." The guy was in Rhode Island, we were in western Maryland at a facility owned by the US Navy and operated by a joint service command we were part of. What I was doing there is not quite as secret as our Chaplain's service, and while a lot of my secrets have been declassified in the past 48 years, I don't have anything in writing from my old unit as to exactly WHAT details I can and cannot share. Many of the sites, but not all, I worked at have been 'repurposed' by other agencies in the last two decades, just as the satellites have been. If you are curious and you look at the current DA PAM 670-1, figure 20-67, you can probably fill in some of the other details of my story.
