The Disco Palace DRM @ 17875 kHz, 6 Aug 2012


Looking pretty good, but I had to expand the demod bandwidth by 200 Hz because the centre was drifting.


I forgot to show the time, so you'll have to take my word for it, but it was around the same time. The center continued to drift, and by the end it had drifted about 191 Hz.


This isn't a big deal; 10.5 kHz demod bandwidth should be sufficient and Dream successfully tracks the drift. But starting out off by 138 Hz and then drifting about 50 Hz over the rest of the transmission doesn't scream stable mixer.
