My top 5 of my best dx using wspr. On 20m the antenna is a half wave vertical. On 80/40 and 30m I used the Diamond W735 with an extra dipole for 30m. This antenna hangs just 2 meter above the lawn.

A friend of me asked if I could detect some WSPR signals on 20m. He has been monitoring it a while without any activity.
I also read the comments of G4ILO on the WSPRnet.org site : http://wsprnet.org/drupal/node/384
I must admit that I was also stuck on 30m.
He made a statement and yesterday I had a day off. A whole day of listening later this is what passed my screen :

Not much.

Hey guys, if you want that propagation monitoring works, we need to activite all bands.

ON3JT_WSPRTonight I used WSPR again to see the activity on 30m. Now I received about 7 stations from the USA, Hungary, Spain, Switzerland, UK and the Czech republic. After a few hours I ticked the 20% T/R option. This switches the transceiver on for 20% of the time and the remaining 80% listening.

And yes, my signal gets out. Using only 2 watts my signal is picked up by VK6KHD, Nigel in Australia. My first.
That is about 14190 km or 7095 km per watt or very very far from my qth :-)

Last saturday night my computer has been running all night long the WSPR (whisper) software from ….. to see if I could receive that mode too. My wife had the night shift in the hospital and could not argue that the computer is making too much noise in the bedroom :-) That is the downside of having the shack in the bedroom.
I set the receiver to 10.138.7 in the 30m band and went to bed.
