Hi all, I think Markus idea is a good start but we have always made it the case that we do not have hard and fast rules on LF because the frequency of operation epends so much on local conditions and it is no good anyone laying down a marker that suits his location but doesnt fit with others. As I said Markus comment is a good guide. However......... Gerhard raises the point of using grabbers in your own continent for tests. This is good and usefull to do....I have done it myself. All that you require is to think about the long distance propagation and time your tests appropriately. For instance US and Canadian stations will not really start to appear until about their ground sunset (well ok, on very good days maybe a little before that) So you could safely do "local" (same continent) tests between your sunset and the East Coast US sunset time. They probably wont take too long and then it is unlikely you will interfere with anyone trying. For a TA contact. Of course you "could" do the test in daytime!! This would actually be more reliable, particularly at present, when the daytime paths are very consistant. You obviously need a grabber in daytime range. The old geoclock is an invaluable guide though I am sure there are other now. Just remember you are very strong at night in your own continent, and try to stay out of the immediate areas where DX signal may be coming in. We are hardly wall to wall QRM on LF and MF yet so enjoy it. Alan G3NYK |
