Hi Stefan
Any info about Reunion Is acty for the coming DX season ?
Not hrd u for a while on 472=20
have been getting good wspr reports on 472 over 3000 Km and VK most =
early evenings VK2, VK5, VK6, VK7=20

  Hi Paul,=20

  Probably you are the only one who is able to pick up the message that =
i will try to send soon. I'm not sure if your RX is running, i just give =
it a try.
  There has always been the question if it can make a significant =
difference, due to propagation effects, if the transmit frequency varies =
by just a few 10 Hz.
  Thus i'm now running an EbNaut transmission on 2 frequencies, sending =
the same message (parameters) and the same antenna current from the same =
antenna:

  f1 =3D 6430.005000 Hz
  f2 =3D 6510.005000 Hz
  Start time: 16.October.2017  13:00:00 UTC
  Symbol period: 15 s
  Characters: 2
  CRC bits: 6
  Coding 16K21A
  Duration: 2h32min
  Antenna current: 200 mA, on each frequency

  I can repeat the message at night but let's give it a first try. Jacek =
asked for a similar test some time ago. He will need a night time signal =
i think.

  73, Stefan
