Hi Stefan,
Hope this not turning into a
20-watt ERP beacon.. ;-) Well just kidding, but see calculations
below.
AFAIK, we are still limited to 1 W ERP in this country since some
borders are less than 800 km away from the 'primary' users. Not sure if this
will change - anyone out there with more info ? From the old (preliminary?= text
at at
http://www.bundesnetzagentur.de/SharedDocs/Downloads/DE/BNetzA/Sachgebiete/Telekommunikation/Regulierung/Frequenzordnung/Amateurfunk/AmtsblattverfuegungenAFu/Mitteilung3862012NutzungFreqBereich472_479kHz.pdf?__blob=publicationFile>
Es
wird darauf hingewiesen, diese Regelung sensibel anzuwenden, Störungen zu
vermeiden und die
maximale Leistung nur dann auszuschöpfen, wenn es zur
Aufrechterhaltung einer Funkverbindung
oder für experimentelle Zwecke als
zwingend notwendig erachtet wird.

Anyway, make the best of it,
and add a few taps at the output transformer to step down the power if
necessary. Remember Andy's nice EIRP calculator (xls) ?
Effective antenna
height = 10 meters
Capacitance = 260 pF (guesstimate but realistic for a
medium sized antenna)
Total resistance = somewhere around 31 ohms
Power
input = 700 Watts
-> EIRP = 27 Watts
Good for DX but not
for the license.
