25 watts EIRP allowed here in New Zealand, but that is because we
are a long way from anywhere!

Hi Markus,
not everywhere!
The outcome of WRC-12 was:
"The maximum equivalent isotropically radiated power
(e.i.r.p.) of stations in the amateur service using
frequencies in the band 472-479 kHz shall not exceed 1 W.
Administrations may increase this
limit of e.i.r.p. to 5 W in portions of their territory
which are at a distance of over 800 km from the borders of
Algeria, Saudi Arabia, Azerbaijan, Bahrain, Belarus,
China, Comoros, Djibouti, Egypt, United Arab Emirates, the
Russian Federation, Iran (Islamic Republic of), Iraq,
Jordan, Kazakhstan, Kuwait, Lebanon, Libya, Morocco,
Mauritania, Oman, Uzbekistan, Qatar, Syrian Arab Republic,
Kyrgyzstan, Somalia, Sudan, Tunisia, Ukraine and Yemen.
In this frequency band, stations in the amateur service
shall not cause harmful interference to, or claim protection
from, stations of the aeronautical radionavigation service."
In Belgium the power limit is 5W EIRP (3 W ERP), I believe
this is also the case in the Netherland, UK and Ireland.
But you are right about the saturation. With the right
antenna (height) it is easy to produce many 10's W ERP with a
few 100W TX power.

Note however that the power scale saturates at 1 W ERP,
which is (by definition) the largest power an amateur can
possibly radiate on LF and MF ;-)
Best 73,

Hello Szigy,
regarding the declared power level in WSPR: Most stations declare their ERP, not
PA output.

From: YO2IS
Hello from KN05ps,
was pleased to take part in the 8 ian JT9 activity.
Lot of signals received, propagation was similar to 2m Es !
very short openings from unexpected QTF's.
Nice QSO with DG3LV in JO53, IZ7SLZ responded to my CQ he was
a solid -23 then nil. Received again OR7T -27, we had a nice
QSO a day before, also wkd DC1RJJ who responded to my CQ !!.
CWNR, several times IW4DXW up to -24 and DF7FC -20 he often is
reporting my WSPR-2 nil in JT9...
My TVRT / IRF540 had only 20 W out into the 41m sloping wire.
it seems that the IC-7000 is not as bad for reception on LF / MF.
Surprised also by the WSPR-2 results, litle confused with the
received signal levels versus de declared power dBm! are real ?...
Enjoy the good winter conditions.
73 & DX, Szigy.ÿþ?ÿþ?
