Does anyone out there know, if there's a Navtex receiver (518kHz and 490kHz) module out there. I'm looking for something small that I can connect to an Arduino.
Alternatively, does someone have a simple LW receiver circuit that would allow to receive those two frequencies with sufficient quality? Most long and medium wave AM receiver modules seem to just jump over those frequencies, they end somewhere around 250kHZ and restart at 520kHz.
The message decoding is less of a problem, I'm more interested in having the RF part done with a working solution I don't need to debug - I'm a software guy after all.
