Thanks for the report of an audible signal….it sure looks solid on the Argo screen shot. That’s why I run it 24/7/52, as you never know when and where the surprise will come from on LF. Thanks for giving me the reason to keep it on, Mike! 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
