LF: 630 meter full size dipole

This may be of interest for your next exploit ...

 

Looking back in my 500 kHz log, I see that on 1/3/2010 I had a CW QSO with WD2XSH/35 in South Dakota ... who was running a full size 600 meter dipole. As I recall his antenna was relatively low at 30 or 40' above ground and he was running only 50 or 100 watts. His signal was weak but solid copy over the few nights that he was active. Distance was 1210 mi / 1950kM. Believe his antenna was 'out in the open' as he apparently owns a good sized farm.

Hi Graham,

Well, as often announced i want to do some tests with a full size dipole for 630m. Maybe the signals will be very weak. QRSS is not usual on MF and so Opera or WSPR will be useful for the tests. However i would have no internet access during the tests...

BTW which information is contained in one OP message? Just the callsign or the callsign+locator?

Thanks Stefan

 

Main thing is , that  all  stations  have the  same  mode  set , but if  you  are  using   the  windows  software , the  internet  beacon  will  show  the  mode  , OP8 or  OP32 ... this  is  where  the  PIC  based   systems  have a  problem. but  if  the  tx  is  remote , its possible to  simply   run Op  on a   web linked  PC to beacon via the  web ..

 

Monitors  can  run  X2   Opera   , one set to  OP8  , the other  OP32  , with some  CPU overhead , but not a problem on  a  'new'  pc better , just the  one  session.

 

If you  have a  day  selected, then  can post  to the  user groups, to  ensure  the  maximum  number of  Rx  stations
