SPAIN [non] The new DRM transmitter of REE at the Cariari de Pococi,
COSTA RICA relay is still bleeding far beyond the legal 10-kHz bandwidth
so touted by DRM as making it a good neighbor to analog signals. June 14
at 0004, shortly after opening of 2-hour transmission centered on 9630, I
can hear the DRM at least as far as plus and minus 20 kHz, not 5 kHz, i.e.
down to 9610 and up to 9650, or slightly beyond both.
Yes, the major brunt of this DRM is in the 9625-9635 band, but instead of
cutting off sharply at the edges, it progressively becomes weaker, and I
can imagine what it would look like on a spectrum analyzer.
So 9625 CBC Northern Quebec is totally blocked for two prime evening hours
so much for Randy Bachman's Vinyl Tap and Saturday Night Blues and their
fan in Costa Rica. It probably bleeds even further than 20 kHz in
proximity to the transmitter.
