Andrey, Chris, Halld=F3r, Dave, Clemens, LF,

Thanks for the reports about my 1W beacon. I'm happy that it is clearly= visible in Moscow and on most grabbers in a radius of 1000km.

Chris, the link you show below opens the same picture you posted last night= . Can you do it again, pse?

Stefan,

A trace of your signal visible here tonight. See attached.

=A0 =A0 LF,

=A0 =A0 Last night i shot my PA again :-( No replacement FETs were availab= le so
i had to stay quite during the night. Replacement parts are ordered now and=
will arrive tomorrow :-)

=A0 =A0 During that time i will run a LF beacon on 136.172 kHz running 1W = TX
power in DFCW-90, starting in the afternoon. If someone can receive that weak QRPP signal, then a report is very apprechiated :-)

=A0 =A0 Also i will do some optimisations on my recently posted PA output = stage
(http://dl.dropbox.com/u/19882028/LF/= DK7FC_137kHz_TX_antenna_and_PA_schemati

interested in general:

=A0 =A0 -C=3D 220pF/WIMA FKP-1 2kV =A0(In series with R, across Drain-Sour= ce)
