Why would anyone want to send am/fec on the SA beacon qrg ? , it was S 9 this evening , still in daylight with something like 1000 Hz double side band full carrier modulation , which makes these things 2K wide ? I don't think operating inside the side band - carrier space is acceptable ?

Hi  Stefan

When are you going to test NAVTEX  (amtor/fec) again ?

I have been using multipsk for decoding with an average score. It could
interesting to see if my "SCS PTC-IIusb" box is doing a better job.
