I knew that CBE is a Class A and that the US 1550's have to protect the
Canadian border as a consequnce. Or do they simly have to protect CBE's 0.5
mV/m 50% skywave? For some stations, the difference is significant. In fact,
if you check out KQXI, Arvada CO (on 1550), you will find a dazzling array
of applications and CPs to improve night sevice. This train of applications
is as confusing as WXLX's. By the old rules, a US station on a Canadian
clear channel had to be at least 650 miles from the nearest point of land in
Canada to be authorized night service. I guess that the Denver area is right
on that line. I think KQXI (or whatever the calls were originally) started
out as a daytimer and at some point was granted relatively low power night
service (this was before odd powers were allowed). I guess that KQXI is now
trying to take advantage of the new rules and, I presume, has been running
into the usual litany of environmental problems that any station that wants
to put up a new directional or even modify an existing one faces these days.

I think that CBE and KNZR in Bakersfield CA (on 1560) are the only two Class
A AMs in the US and Canada that don't run 50 kW fulltime. Like CBE, KNZR is
10 kW at night, but KNZR recently increased its day power to 25 kW.
