I am active on Digimodes and have worked a lot of state side and DX stations using Olivia, PSK31, and JT65A modes mostly. I have transmitted my signal on WSPR mode a total of about four hours several times the past two weeks on 10.402 MHZ at times when many other stations are present there. I also go to the WSPRnet.org site and have seen my station in the database as a station that has uploaded many spots.
Here is the mystery: No one has ever heard nor uploaded an indication they have spotted my transmission. This is twilight zone territory. I monitor my transmitted signal using fldigi so I know my transmission is going out (5-10 watts) and is in the correct range of frequencies. Can anyone give me any suggestions why no other station has ever heard me on WSPR? Thanks for you input in advance. AB7JK
