CHU can be improved upon, at least to the point of having 2 transmitter sites. This at least would allow for transmitters at some sites to be turned off while others are turned on -- allowing for the upgrade to pay for itself with respect to the power bill. > I've just gone through a round of audio driver upgrades for the WWV and > CHU radio services and the IRIG signal. The documentation has been > rewritten as well. I'm hoping that the CHU upgrade might find users in > Canada to support the continued operation of CHU with three frequencies, > even if the 7335 kHz frequency is moved.
