Shortwave Broadcast / BBC Clashes with itself on 12096.68 kHz? Twente WebSDR Receiver
« on: December 12, 2013, 0243 UTC »
Giving credit where credit is due, the work of RW observer and his number stations observation using the Twente WebSDR Receiver motivated me to go tinker with this site again. Presently there are over 60 receiver sites available at WebSDR.org.
Of particular interest is the Twente general coverage Receiver of from 0-29.6 kHZ Not only do you get a high performance receiver, the chat box feature also enhances the experience (so far).
At about 00:30 utc the BBC was observed on 12096.68 kHZ with a strong echo. This echo stimulated considerable speculation and comment given the propagation conditions which were poor for DX at the time. At about 01:00 BBC Signature Interval Signal was observed co-channel with male presenter. Promptly at sign off, interference Echo and interval signal vanished and the typical broadcast continued. Apparently some sort of BBC scheduling difficulty? I was a Deutsche Welle Technical Monitor back in the day and don't recall DW ever causing interference to itself? This may be a first, at least it is for me. It should be noted that my times are for illustration purposes as my comments scrolled off the Chat box feature and I am working from memory
In addition, it should be noted that there are several interesting novelty receivers at this site such as K6FRC's 10 meter beacon Receiver and the receiver in Dresden designed to observe Cube SAT's as the tumble around in low orbit. I did not have any such luck picking up a Cube Sat (Shoe boxes in space program) but I had fun anyway.
I really like the waterfall displays a lot more than analog or digital. Have fun with that.
