I have 2 mini's, each put out 4-6 watts. The 20 meter version is rev1, the 40, rev2. Each is setup for WSPR. Each is setup using the exact same process. I set them at about 1.5 watts. Same resonant antenna, a vertical with a good radial system.
40 meter rev2, heard everywhere. The spotting is heard all over USA, and the Caribbean.
20 meter, rev1 heard nowhere. No spotting at all.
Both radios have been used quite successfully for QSO's.
Any ideas what I am doing wrong?
Thanks, Gary W0CKI
