Dear Marcin,
My /p ground is a copper band of about 20cm x 25m x 1mm (abt 25kg, so no
problem in the wind)
With this band, just rolled out within 1...2 Minutes I get a overall loss
resistance of 50...55 Ohms (earth losses, wire losses, coil losses and, of
course, the radiation resistance) ;-)
Are you qrv or just receiving until now? We always could try a qso if you are
interested.
73s to all, Stefan/DK7FC

Dear Stefan, LF
Very good copied your signal in Poland.
Why use your portable ground system?

Dear Lowfers,
This is my first mail to the reflector and so i want to say hello to all :-)
It´s nice to be able to participate now here although my activity will stay
on the band mostly ;-)
If there will be no weather problems this evening I will agn be qrv on 137
in CW (abt 136,8) and/or QRSS3.
Since abt 3 weeks I am qrv again. Since I live in a city I have no
possibilities to be on LF, even not in RXing (QRM)... Therefore and cause I
like to be in the nature I am now qrv in /p. I use a kite antenna, 100m up
(!). This should have a radiation resistance of 0,83 Ohms. My overall
resistance is abt 30...55 Ohms, depending on the ground a achieve. So you
can imagine abt the ERP. I have a 1KW class E PA that I use with limited
power. But The ERP easily reaches the 1W ERP limit, as one can imagine..
My RX is still poor but I am working on a receiving loop. Now, I use the TX
ant for receiving that causes some problems ;-)
It would be nice to get some QSOs or even RX-RPRTs tonight. Until now I got
2 QSOs in each activity ;-)
Best regards,
Stefan / DK7FC
