I will add Opera 477 to my listening set up. This can be done by either using a fourth software receiver in SDRConsole running on an Afedri SDR. However, lately I have been playing on NAVTEX 518 kHz with a 20 Euro RTL-SDR V3. This has been a revelation and it is about on par with the Afedri! It is a bit deaf at LF, hence I am using a tuneable pre-amplifier preceded by a 530 kHz low pass filter. This way it becomes a decent receiver. Just for fun, I will set it up for Opera 477 kHz and let it run overnight. 73, Roelof, pa0rdt
