Hi Stefan,

Anyway, make the best = of it,=20 and add a few taps at the output transformer to step down the power if=20 necessary. Remember Andy's nice EIRP calculator (xls) ?

Effective = antenna=20 height =3D 10 meters
Capacitance =3D 260 pF (guesstimate but = realistic for a=20 medium sized antenna)
Total resistance =3D somewhere around 31 = ohms
Power=20 input =3D 700 Watts

-> EIRP =3D 27 Watts


Good for = DX but not=20 for the license.

73,  Wolf .
