<Didn't review your math, but the more important question is, "how old is <your noise data?" In my experience trying to work EU on Topband now as <compared to c.a. 2007-8 is vastly more difficult thanks to higher noise <levels on both ends. Back then I could work EU on CW; now, with better <antennas, I need the 10 dB advantage of FT8. In the past six seasons <I've heard six EU/U.K. stations on CW, two were able to hear me. And <those were all during one of this season's contest. <Bottom line -- if your noise data is ten years old, I'd add 10 dB to it; <if it's older, probably more. <73, Jim K9YC ## Clearly whats required is a long overdue increase in TX power limits on 160 band...and also 80+40. That or arrl legal remote RXs..... pick one. Jim VE7RF _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
