WSPR (Weak Signal Propagation Reporter) is a piece of software written by K1JT starting in 2007. I have been doing this successfully that year and a little bit in 2008. I use my TS690s with power output fully turned down, which gives me about 2 watt then. I only have one antenna this is my 40m full size wire dipole. With only 2 watts of output from the transmitter I "risk" to do 2 minute transmissions without matching the antenna. 20m is not very successful, but 30m works OK for me. 40m is good with a very good antenna match here. I suffer somewhat from the overall noise present on the short wave bands, but still I can receive stations from all over the world. If you want to know more about WSPR have a look here: WSPRNET.ORG. This should give you an idea of what is is. After a long pause, I ran this WSPR again. The 30m band has been most successful. Reason for this is of course the highest activity is here. 40m worked too, but with only 20% of the activity compared to 30m, you will get lessd response of course. Activity on 20m is weak - so was the response. You will hear my signal again.
