Hi Garry…..that looks like a consistently solid signal in your Argo snip! Things are starting to dry up around here, as most of the snow and ice has either melted or evaporated. As a result, the ground conductivity may be effected, which can change the ERP. Thanks for the report. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
