But the long haul stuff seemed to be doing the best. The KH6's were blasting thru fairly well. MK Hawaiians were reported strong on 50MHz as close to me as Memphis - unfortunately I was at work at the time! Channel 2 TV from Honolulu was definitely logged in Vancouver. There is evidence to suggest the same station was seen in Shreveport and the Lower Rio Grande Valley in extreme south Texas. Propagation characteristics almost seem like a cross between Es and F2. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |

Dang...Didn't even think to look at the tv...It's kind of a hassle, as I have to unhook the cable, etc...The KH6's seemed pretty F layerish. Real steady for long periods of time. Almost like 10m. Some of the stateside stuff might have been e layer. MK |

Some of the stateside stuff might have been e layer. MK See, I *knew* there was a good reason I don't have cablegrin! The Vancouver DXer was certain the opening was double-hop Es. The E and F layers are both ionized layers of the upper atmosphere that refrace radio signals. It's already accepted that a F1 layer merges with F2 at certain times - my question is whether maybe both F layers merge, at least partially, with the E layer on rare occasions. The immense magnetic storm we've experienced would certainly seem capable of triggering unusual effects. The Texas and Louisiana reporters did feel the signals had F-layer characteristics - severe multipath (much easier to detect with TV signals than with SSB!) and a relatively stable MUF within the TV channel. Given the difference in locations and latitudes, I suppose it's possible there was double-hop Es and F2 at the same time! -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |
