The Mighty KBC Digital Transmissions @ 7375 kHz, 3 Mar 2013


Hello Eric and KBC listeners everywhere.

Kim Andrew Elliott here, but probably not listening, because just about now I'm giving the keynote speech at the Winter SWL Fest near Philadelphia.

So would someone please record this for me?

Coming up at just before 0200 UTC, MFSK32 with images will be centered on 1000 and 2000 Hertz.

This is The Mighty KBC on 7375 kHz.

Pretty awesome reception from this new transmitter and frequency, S9+10 or greater through the whole thing, although the broadcast started late. First digital segment was perfect across MT63-1K, PSK-125R and MFSK-32. All had the above text.

The second segment was images, which is blah. You know my opinion on using a digital FSK mode to transmit an SSTV image.

Apparently it came back yesterday. Word on the street is that the DRM transmitter broke. Word on the street also says that Montsinery is going to be shut down at end of month.



Anyway, they must have done something to the transmitter, because the sidebands are much better controlled. This leads to an immediate SNR gain.


SNR peaked at around 28.2 dB, probably the highest ever for TDP. There were some severe fades in the last half hour, so if I were logging for drm log plotter, it'd probably be like 99.95% or thereabouts.


Splatter begins to become noticeable when subcarriers breach -80 dBm.
