Hello Jim,
QRM is less in the early morning and
there are some stations who have not yet received the signal without doubts.
Thus, i will start with DFCW-600, transmitting some letters out of my call.
If i am visible on my grabber in DFCW-60,
the 600 transmission will be also visible, of course. Additionally Markus will
try to catch the signal in DFCW-60. I will do this later.
The new PA will be tested in the first
time. I have an adjustable transformer (0...260V (230V input) / 1 kVA) and
will slowly increase the power of the new PA watching the temperature rise and
so. So, maybe the first letter is of unstable amplitude. But if the whole
system works without problems and the earth losses are significantly reduced
by the earth rod, my ERP could reach the 5 mW level! This will be my strongest
signal ever and could be hopefully detected even with more QRN.
Wish you good luck on the home QTH. And
tnx for the your new RX circuit with the BFO. A very good idea for checking
possible QTHs for compact VLF antennas!

Dear Stefan, LF Group,
I will be attempting to receive
your sigs again tomorrow morning. Not sure
if I will be able to use the /P
location as last time - if this is not
possible, I will try from my home
QTH, although this has a higher noise
level.
Please could you give
some idea of your planned schedule - in particular,
will you be starting
with DFCW60, or DFCW600 mode?
Good luck for the tests,
Cheers,
Jim Moritz
