[Scanner] Remoted ARTCC facilities

[Sheldon Daitch]

It is very possible that there are some transmitters located at the
actual ARTCC facility location, but I suspect there are very few
ARTCC locations do not also have remoted transmitters.

These remoted facilities are more important for the low altitude
en-route structure, because of the limited range of the VHF radios
at the lower altitudes, plus the multiple frequencies scattered across
the geographical areas allows for more efficient aircraft handling
when there is more traffic in the air - not as many aircraft on the
same frequency.

As an example, on chart L-36, the junction of the ARTCC coverage
for Atlanta, Jacksonville and Washington centers is a bit NW of the
Cheraw, SC airport.

A general aviation pilot flying from, say Florence, SC to Rocky Mount,
NC and using ARTCC low altitude routing facilities would initially
be in contact with Jacksonville Center on 133.45 MHz, remoted at
Florence, then handed off to Washington Center 135.3 MHZ, remoted
at Samson,  NC and then over to the Washington Center frequency of
118.475 MHz, remoted at Rocky Mount, NC.

Assuming the chart at:

is correct.

Even the high altitude structure has remoted frequencies, but they
are generally further apart, but with the higher speeds of aircraft at
these altitudes, the aircraft will be handed off from one frequency to
another rather frequently, as well.

I may have missed it, but Paul, did you ever post the Denver center
frequency?

Looks like chart L-10 ought to cover your area.
