OK, I now understand the new rules. In other words, you might as well
say no protection. If KNTS wanted 50 KW directional North, they could
probably do it. It is hard to tell exactly what the signal will do to
1220, but with 6KW, it will probably ruin it except on really good cx to
the East. But it is hard to tell. Also the directivity of my beverage
depending on the frequency. Some channels, the directivity is much
better than others. At least there are still some channels that the
beverage works well on. Portland signs off around 10:30 PM on 1330, and
my nearest going East in Wichita, Waterloo, etc,. So things aren't that
bad.

I wouldn't come CLOSE to saying no protection. The ratchet rule is VERY
restrictive, and is the reason that, after the power increase, KNTS won't
cover anywhere near the amount of territory east of the Bay by day as it
does now. (Though as Scott points out, the loss of population served will be
much less, percentagewise, than the loss of area served.) Any AM that
proposes a change of any consequence must demonstrate that existing
prohibited overlap with co-channel and first, second, and third
adjacent-channel stations wiil be reduced by at least 10%. In a few cases
(very few), stations have been able to (financially) induce the affected
stations to modify their operations to reduce prohibited overlap. The most
prevalent strategy, however, is to buy and take dark the affected stations.
However, the FCC permits taking stations dark for the purposes of upgrades
to other stations only in cases where service to the CoL of the station
going dark would not be significantly diminished. Recent FCC actions suggest
that, to upgrade another station, the FCC won't allow taking dark the only
station licensed to a community, even if the community is covered by 10 or
more technically excellent AM and FM signals from stations licensed to
nearby communities. This whole area is a technical and legal briar patch.
Several consulting engineering firms are making a nice living negotiating
this regulatory thicket for broadcasters who still feel that their AM
properties are valuable and are willing to invest in them.
