  Hello Jim,

  QRM is less in the early morning and there are some stations who hav=
e not yet received the signal without doubts. Thus, i will start with=
 DFCW-600, transmitting some letters out of my call.=20

  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 tr=
ansformer (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 wo=
rks 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 str=
ongest 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 circ=
uit with the BFO. A very good idea for checking possible QTHs for comp=
act VLF antennas!

  73, Stefan/DK7FC

  Dear Stefan, LF Group,

  I will be attempting to receive your sigs again tomorrow morning. No=
t 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 no=
ise
  level.

  Please could you give some idea of your planned schedule - in partic=
ular,
  will you be starting with DFCW60, or DFCW600 mode?

  Good luck for the tests,

  Cheers, Jim Moritz
