Good Day All

Would someone please point me in the right direction. I have used wspr on all bands but on wsprnet I can never see my callsign being transmitted. I can only see who I can hear.

My set up is as follows

Rig: Icom 7600
Antenna: Multi-Band 1/2wave Wire Dipole.
Output Pwr: 5watts, then 15watts and then 20watts.

Appreciated any tips

Thanks
