CKZN-CBU transmission solution:

http://cbc.am/cbc-src.htm

Canada's rural and northern populations are for the most part not fully
served by AM & FM radio stations during daytime hours. Although CBC North
runs an extensive AM / FM and TV network for northern Canadian residents --
there are still millions of square kilometres that the CBC-SRC will never be
able to reach with its current broadcast network.

The lack of daytime information radio network service does not help northern
and rural residents in their day to day lives. It goes without saying that
the lack of access to an information radio service in Canada's remote
regions increases the demands on expensive to deliver federal and provincial
services. Poor delivery of basic government services has led to a negative
relationship between northern and rural residents and Canada's southern
urban population.

In a matter of speaking CBC-SRC has pretty much failed to meet fully the
news and information needs of all northern and rural residents, since these
residents fell into the revised CBC-SRC mandate in the 1970s. This mandate
is providing a basic information radio service to all of Canada's regions.

Most of Canada's populated remote areas can be reached cost effectively with
two shortwave transmission sites. Shortwave is an ideal media for delivering
radio programming to remote regions during morning, daytime and evening
hours. The proposal before you is for a transmitter site in British Columbia
that could serve western and northern Canada and a transmitter site in
Newfoundland that can reach Labrador, Northern Quebec and regions in the
high arctic that are poorly reached by the BC transmitter site.

Technical Notes

It is assumed that the shortwave transmitters would be fully Digital Radio
Mondiale (DRM) compatible. DRM allows for FM radio quality digital audio
over very long distances using shortwave.
This proposal is for a 2 frequency nationwide network using the 49 meter &
41 meter bands. In total 4 frequencies may be required to provide daytime
and nighttime transmission with 95% availability. This proposal requires
using 2 variable frequency automated 50 kw DRM SW transmitters.

The 2 DRM transmitters would be expected to run around 16 hours a day, out
of a shortened 112 hour week transmission schedule. In cases of national
emergency, the network could run 168 hours a week with 5 different voice
only audio streams.
I do not expect a new frequency allocation for this shortwave service, as
the CBC-SRC is already using three shortwave frequencies
(http://www.cbc.ca/frequency/shortwave.html). CBC-SRC needs to make a
uniform allocation of 40 khz for domestic shortwave broadcasting within the
49 m and 41 m bands. This allocation would be made for use by all domestic
shortwave broadcasters.

These area coverage computations do not represent full optimization. The
frequency and antenna types may need to be slightly altered so as to achieve
the goal of covering 98% of Canada's land mass with a reliable shortwave
service from two transmitter sites.

DRM = QRM you stupid 'tard.

This is "assumed"? Why? Is the objective to squander as much bandwidth
as humanly possible? While we're at it, maybe we should burn their
forests and poison their water.
