Hi Herb NH8S was on this morning (1200Z). Not strong, running split, and was busy putting NA into the log. After I got him on 160, then on 80. I expect he will be on for a few more mornings, so you have a few more chances (fingers crossed). Tom - VE3CX On Tue, Sep 11, 2012 at 2:30 PM, Her

Jiim, Nice work with 5 watts. I can't hear a peep here in the Eastern Caribbean on TB with three Beverages pointed that way. I did work N8S in 2007 without any problem. Summer time DX is problematic (whatever that means). But D64K was not a problem last month on TB although I don't believe na

NH8S is the call sign for this one. You may see KH8/S listed as the prefix here from some sources but note that KH8/S does not necessarily mean the call is KH8S. I've seen a few cluster spots already for KH8S -- these are simply bad spots. N8S was the last DXpedition to Swains in 2007. Mike N1TA

I never take anything for granted when accuracy is desired. I use a noise bridge and my receiver to zero in on the exact frequency, the noise backround null is very pronounced with good coax. Beats turning on an expensive VNA. Carl KM1H - Original Message - From: "HAROLD SMITH JR"

Tom I think everything is real quiet while a bunch of folks are busy looking at manuals and crunching numbers with their analyzers. Wes, The problem Jim suggests is real, but the numbers are so small at HF for normal good cables they are meaningless. Until we get a really small cable, or
