Well let me ask you this: I, too, would rather use
'domestic' shortwave time service, but perhaps I'm
not understanding CHU? Does CHU broadcast from
an atomic clock in Canada - or are they just a
repeater for the WWVs?

It's the Canadian government's own time station, operated by the Institute for
National Measurement Standards of the National Research Council of Canada, which
has its own atomic clock.

FWIW, it also has a feature WWV/WWVH/WWVB do not - CHU sends a data signal at
seconds 31 to 39 which allows any computer with a Bell 103 compatible 300 baud
modem to receive/decode an accurate time source.

(If the Bell 103 standard sounds familiar to anyone here, that might be because
it's also the standard we hams use for packet radio on HF - so if your station
is already set up for that, you now know something else you can do with it)

The station is located at 45° 17' 47" N, 75° 45' 22" W, which is near Barrhaven,
Ontario, a short distance from Ottawa. They transmit with 3 kW on 3.330 MHz and
14.670 MHz, and 10 kW on 7.850 MHz. Any sources you see that say CHU operates on
7.335 MHz are obsolete - they moved from there to 7.850 MHz at 0000 UTC on
January 1, 2009 to escape interference from broadcast stations.
