CHU is probably unique in the world in that it is transmitting the carrier and JUST ONE SIDEBAND. It transmits only the upper sideband. This makes it clearly detectable by our receiver. As Dean pointed out to Wayde, all he had to do was &#8220;zero beat&#8221; the carrier with the PTO signal (tune to the point where they are on the same frequency and the audio tone disappears). Because there is only one sideband, the direct conversion receiver can demodulate it very well. If there had been two sidebands, this would have been a standard AM signal, and our little receiver &#8212; which does very well with SSB and CW &#8212; would have been unable to demodulate the signal without distortion.
