Hello Lowfers, I can confirm that the offending Navtex station is not station H as I just decoded a transmission from it and when the message finished so did the transmission. I'll watch for station P which is at Thunder Bay and see if it's the culprit. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
