I forget the official name for this type of LW service. NAVTEX is only broadcast on one frequency (518) as far as I know. I wonder if you might be hearing Differential GPS? Speaking of longwave, I have a loud digital signal on 100 kHz. Does anyone know what it is? LORAN? I believe the Milwaukee DGPS is on 297kHz, check a USCG site for details. LORAN C is on 100kHz Dave |
