Hello John and group,
Thanks for the MSK tests, and for the info ... well then let's say Ko was the first in EU who successfully decoded MSK here. I am still a bit sceptical if the signal wouldn't suffer from phase disturbances due to groundwave/skywave interference too much, since there is less phase reserve than in a BPSK signal (of course, if a coherent demodulator was used).
But because MSK08 and MSK31 will never be "very-weak-signal modes" compared to QRSS, JASON, WOLF and Co, it shouldn't be a big issue.
I have returned from the 440 kHz receiving session to a very very quiet 136 kHz
band, and am still hoping for some activity in regular CW, or whatever
