<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.

## 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.
