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!
73, Stefan/DK7FC

Betreff: LF: Re: DK7FCs 5th VLF experiment...
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
