Dear Uwe, LF Group,
The calculations look OK to me - the results seem to be in line with
other measurements. The ERP calculated from FS measurements is about
0.8dB below the value calculated from antenna current and Rrad; this is
also normal. I would be interested to know the "environment" of your
antenna, ie. is it in an urban or rural QTH, are there many trees, etc?

first an second image.
Between QTH DJ8WX and QTH RegTP monitoring station (1,7km) where the FS
measurements have been made are meadows and pieces of wood (80%wood en toto).
Topography: Ground of my aerials 3m above NN (moor) and of the monitoring
station 34m above NN (glazial dune sand).
meanwhile I updated the site PWR.htm .
Best regards
