Ooh, what was my previous test? I've done several previous tests in the last 24 hours :-) And please define short range :-) Probably you mean VLF (?). Well, i know that OK2BVG received my complete call in DFCW-600 on 8970 Hz, while i was using the fixed LF antenna here and run 350W...500W RF power. So this is to be beaten. OK2BVG is in about 600 km distance from me. So there are chances for UK stations as well. I think DF6NM or maybe DD7PC would be a good partner for first digimode tests. Not to forget Paul Nicholson!

If you  can  generate  the signal  of your  previous  tests , I don't  think  the  range  will  be that  short  !!

Ooh, what was my previous test? I've done several previous tests in the last 24 hours :-)
And please define short range :-)

Due to the  long  tx pulses  of  OP4 Hr  , the  signal  will  also  show  on spec-lab , so  test  data  is not  lost  , if  decode  fails .
 
The  software  produces  the  8K audio  tone  via  the  sound  card and has the com-port  on/off  keying  output as well  ,  normal  sound cards  are  suitable  , the  software inputs  directly  at  8K  using  sound  card  as  SDR
 
If you  have a  target  date ,  I can  post  in the  Op  group  for  monitor's

I'll give it a try Graham. The problem may be to find monitoring stations in a short range...

Hi all,

Hmmm, theoretically we can generate every WSPR speed now. Markus, should we try a WSPR-256 on VLF/ 8970 Hz? :-) I still have the big coil in the cellar and the band looks fine :-)
Remember the "old" times... http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html
