That's more like it!  (I think my conversion to rms went wrong.) 
I'll use the formula below in future.
         (Epk)^2
Power  =  -------
           2 R


Many thanks Andy.


By the way, the QRN (static) on 136 kHz has been high here in
Chepstow for a couple of days, and is currently peaking S9.  But
I did manage QSOs earlier today with F6CNI (RST 569), G8RW (469),
and G3OLB (599).  I also heard PA0SE (569).
