Hello All,
We have got a special permission to radiate 1kW ERP (!) in the
135.7 - 137.8 kHz band during our "dxpedition" to Karlsborg on
Saturday the 27:th of November. SM6PXJ, Christer, will bring his
new 1 kW TX. The antenna efficiency is not known to us but it is
probably 50%, or more, so we will be able to radiate at least 500 watts.
We will have a 200 watt TX as backup in case Murphy decides to
blow up all spare MOSFETs...
We expect to be QRV from Saturday afternoon and we will continue
until dawn on Sunday.
We estimate there is a slight chance that our signals can be heard,
or at least detected, across the Atlantic ocean. Aim your loops at
Sweden and load some FFT software into your PCs (Spectrogram etc).
This may be the last chance to hear LF signals from the huge antenna
in Karlsborg. The old antenna will soon face the same fate as the
antenna in Annapolis did just weeks ago...
Suggestions for frequencies, sked times etc. are welcome. Write to:

Hello All,
SM6PXJ, SM0AOM and I are planning a 137 kHz dxpedition to
the transmitting site in Karlsborg on Saturday November 27.
We are going to use the old "T" antenna which is about 210
meters high.
- The special callsign will be 7S6SAJ.
- We will bring equipment for slow CW / QRSS / VCW.
- We will probably get permission to use more than 1W ERP.
We have not yet decided on frequencies, sked times etc.
Suggestions are welcome.
Stay tuned for more information.
