Hi Roelof,
The second and third SAQ transmissions were also clearly copied using
the SM6LKM converter/FT-817 and your mini-whip design. This was the first
time SAQ was heard here using a mobile RX. It was in a quiet location,
a km from mains lines and other RF pollution. SAQ became quite weak when
the RX was in the forest however. The trees must be good conductors at
VLF.
Is the low-power miniwhip mentioned below the same new one designed with
help from G4COL with a J310, Rs= 47-270 ohm and the FT-37-43 xfmr? I'd like
to try that at VLF.
73 and congrats to all who heard SAQ.

Hello all,
The first scheduled transmission of SAQ today has been received very well here.
There are still 2 more transmissions today: starting 10:15 UTC with a messagae
at 10:45 UTC
and 12:15 / 12:45 UTC.
My PERSEUS SDR is available for those who own a PERSEUS and my KiWiSDR is also
on line, each
connected to its own low power mini-whip, which shines at VLF.
