Saw this WSPR beacon again last night:0230 -7 -1.9 0.137569 0 MQ3MLV RQ57 17 3756 I can contribute a single event to some phantom noise and signal beating. However, a second occurrence with same call sign and grid square? Seems improbable. Certainly the call sign and grid square could be intentionally (or unintentionally) false. MikeAB1AW
