Way back I had a little slding world map with a Greyline chart on it that was supposed to tell me when I would get good DX. It is one of the FEW things I sold on Ebay. Perhaps I shoulda kept it. For NOW I need it desperately to tell me WHEN I have a shot at the T32C on 160M This morning I tried again, and at sunrise, I DID hear them briefly, but not good enough to make a contact. Maybe it WASN'T sunrise. What is the determining factor of a "SUNRISE"? Is it when the sky starts to lighten from Darkness? Or when you actually see the SUN coming over the horizon? How long does "Sunrise" last? And with this little chart, it seemed like you had to coordinate Sunrise here with Sunset THERE for it to work. Since I have such a MARGINAL 160M station, I need to know EXACTLY when to call the T32C. 160 is the ONLY band (except 6) I am short on, so I am Desperate to make the contact. So just what is this "GREYLINE" stuff and how does it work? It MUST work or no one would be using it. What bands does it work on? Any QRZeders use it?
