As always, China Radio International was booming in on multiple frequencies. But as I tuned them in, I noted something strange: a very distinct echo on the signal (you can hear it in the video above). Very strange. Kind of like the Long Delayed Echos we&#8217;ve all heard about. I started thinking of explanations. Might this be some weird regen reverb effect? (You see &#8212; I&#8217;m still wary of these regens!) But no, I checked &#8212; the echo was there when I listened with my superhet HQ-100. Could it be that this was some strange multipath effect, perhaps involving multiple powerful transmitters in different locations? I was listening to the 0100-0200 UTC (20 Aug 2014) CRI English language service. (The echo continued when they switched to Chinese at 0200) I think the frequency was 9580 kHz. An SWL website says the transmitter was a relay station in Quivican, Cuba. <\/b><br \/> <b><br \/><\/b> <b>What do you guys think?
