No trickier than the shrinkage-gap on 30-meters.

Several years ago GEARVAKf (the 'f' is silent) revealed the discovery that
radio waves were gradually slowing down. Found during experiments conducted
by our own Dr. Elwood P. Lishnus and Dr. Avruell U. Harnishe of the
GEARVAKf Scientific Studies Committee, the Harnishe-Lishnus Effect has had
a profound influence upon the manufacture and design of amateur radio
equipment and other devices that make use of the radio spectrum.

Originally, radio frequency drifing was thought to be a minor problem
within receivers and transmitters brought on by unstable heating and
cooling of frequency-determining circuits. That theory was abandoned,
however, when the slowing of the radio waves forced the electronics
industry to change its frequency measurement system from the
cycles-per-second to the Hertz standard. New equipment manufactured under
the Hertz standard did not drift, whereas old gear made under the
cycles-per-second standard continued to drift from set frequencies.
Observation of this phenomenon led to the discovery of the Harnishe-Lishnus
Effect in 1966.

The early experiments, however, dealt only with frequencies below 10 MHz.
Last year, Drs. Harnishe and Lishnus made a series of observations of the
slowing of radio waves above 10 MHz and found that they vary at a much
different rate than those below 10 MHz.

Surprisingly, they found that the lower frequencies are actually pulling
away from the higher frequencies, leaving a gap in the middle. That gap
just happens to fall right in the new 30 meter amateur band between 10.109
MHz and 10.115 MHz. The FCC won't let us operate there because there are
no frequencies to operate on! Any rig loaded up in the gap would see an
infinite SWR and instant destruction. The Harnishe-Lishnus Effect provided
early warning and probably saved thousands of dollar of equipment from
ruin.

Oh dear, what I meant was that it would be quite a trick to widen 75
meters because once it was widened, it wouldn't be 75 meters any more!

Yeah, I know - pretty lame, huh?
