No the commentary definitely mentioned LBC, as though somebody had powered up the transmitter one last time.
And non-english.... I usually check a website call mwlist. There you can compare to live streams from the web and thus often
find the origin. In this case, there was no match. So it is is guess work. My bet is still on Trans World Radio.
Today I made my own synchronous am receiver in gnuradio and tested it on 198khz, 648khz and 1611kHz. It is not perfect yet,
but it handles the deep fading on radio Augusta well. The ultimate goal is to add in some side channel interference suppression
for channels like "shortwaveradio.de" on 6160kHz
The first picture shows that the carrier is locked (ideal is all points on a horizontal line. Interference causes them to deviate)
The second picture shows the desired audio signal, i.e., the in-phase signal, in blue and the quadrature signal in red.
Ideally the red one should be zero apart from some ambient noise.
Any interference from an side channel will affect both signals, which is the key to using the red signal to
(partially) suppress interference in the blue one. The current decoder does not handle that yet.
And here is a waterfall
Radio Augusta has a really cool website as well and a high quality audio stream on there (the medium wave stream is degraded by weak signals
and fading, which is why it is a good test channel). Some of the programs are really amazing and/or unusual. And they have no commercials, except for some jingles with ship horns and see gulls, and some announcement that they are looking for deejays.
Keeping the dream alive...

1611kHz in between various other pirate stations.
