The Mighty KBC Digital Transmissions @ 9450 kHz, 24 Feb 2013

I actually managed to reel something in at S9+10.

It's missing the period after gmail, but I think this was an actual typo and not due to bit errors over the air. On the question of whether frequency of the transmission within the passband matters, for SDR's that have a pure digital path after ADC it won't, so it didn't.

MT-63 2K:

This flmsg actually failed checksum on both the simultaneous voice/data and data only transmissions. But the content came out okay.

I don't know why, but 9450 kHz into Toronto has always been pretty lousy. I tried WebSDR once again but despite being something ridiculous like S9+50 in the first half hour, by digital time it was around S7-S8.

But for some reason, parts of the US seemed to have pretty solid reception. The following are decoded off of a recording from The SWLing Post.

WORLD RADIO DAY

13 February was World Radio Day — a day to celebrate radio as a medium; to improve international cooperation between broadcasters; and to encourage major networks and community
radio alike to promote access to information and freedom of expression over the airwaves.

WITH THANKS TO THE MIGHTY KBC

PSK-125R:


"Shortwave radio can provide service where other platforms such as satellite, FM or Internet are unavailable due to high cost, geographical location, lack of infrastructure, or
even during natural or man-made disasters. ... Shortwave radio ... reaches across the digital divide to the most disadvantaged and marginalised societies."

Personally, this slow-scan stuff over MFSK is kind of pointless. If we're going to need a certain minimum of processing power to receive this stuff at all, then send the image as attachments over flmsg.
