Ok  Stefan
 
Well  GM4SLV  is   monitoring  at the  moment ,    I see  you  did   decode during  the  day    round  0800  he  was  reporting  -30 dB  , that's  very  close to the  limit , as he  has a  quiet location  -31 -32 may be possible ......
 
Interesting  , 0400 / 0600  no  decodes  ?
 
Last  night  your  level   was  -8 dB  , and  would  of  been  ok  for  CW  qso  , if  you  could  receive  my signal  of  course !
but  for  most of the  spots, the  power level  was  20 dB  over the  noise floor , so  1 watt should  decode at most monitors
 
 
Q  not  sure  on the   476.5 ?

Hi G.,

Yes i know, thanks.
Well, it is still the groundwave distance. There are some stations in PA monitoring but this is to far for the groundwave at this power level i assume.
DK8IZ is 17km distant. I didn't know that there is someone who watches the band so close to me.

But you should decode me at this power level at night.
Is my announcement for the common CW sked at 21 UTC on 476.5 kHz visible?

So far  so  good then !
 
The minimum   decode  level  is   round   -31 dB  ........
 
From  the  map, you  can see  what  stations  are  monitoring  and  what  qrg

Hello MF,

I just started a QRP beacon on 477 in OP4 mode using 1W TX power (not ERP).

Maybe someone can receive me?? :-)
