FSS on IFR Enroute charts

You're saying that because the book is OF facilities, it's expressed
from the facility's point of view. But the other possibility would be
that because the book is FOR pilots, it is expressed from the pilot's
point of view. At least that was my thinking 25 years ago as a
student pilot, but maybe I'm denser than most

Cheers,

All true, except that none of those references actually specify that
it's the FSS that receives on that frequency rather than the pilot.
It may be obvious once you know it, but until then it is a question
almost every pilot faces-- hopefully not at the instant that he really
needs to know it, because at that point it's almost impossible to find
it!

read the legend pages in any Airport Facilities Directory under the

"Communications," It's amazing what you can learn by reading legend

The AS/FD answers your question by saying "122.1 is the primary
receive-only
frequency at VORs. 122.05, 122.15, and 123.6 are assigned at selected
VORs
meeting certain criteria." (No word on what those criteria are.)

When looking at a VOR navaid box on an enroute chart, and it says the
FSS station frequency on top of the box, such as 122.1R, does that
mean receive only for them on that frequency or receive only for the
pilot? Does the pilot listen on the VOR and transmit on 122.1
(receive only for them)?

Also, it says the FSS name below and outside the navaid box, with the
L-shaped sides. After reading the chart symbols, it says this is
remoted to a navaid site, does that mean to that VOR it's associated
with? I'm looking at L-2 by Sacramento (Rancho FSS)...- Hide quoted

It becomes pretty obvious when you consider the equipment in the
airplane: The VOR receiver in the airplane receives in the range of
108.00 to 123.95 and there is nothing in the airplane that transmits on
those frequencies. I.e. you cannot transmit on a VOR frequency. Think
about it: if you could, it would disrupt the NAV for other aircraft.

The VOR frequency range is 108.0 mhz to 117.95 mhz. My VHF transmitter
will certainly transmit on frequencies between 118.0 mhz and 135.95.

Do they actually have to say it? The A/FD says, "122.1 is the primary
receive-only frequency at VOR's." If you're trying to communicate with FSS
through a VOR, are you going to receive on the VOR frequency and transmit on
122.1, or are you going to receive on 122.1 and transmit on the VOR
frequency?

You'll figure it out when you try to tune the VOR freq on your comm
radio.

I just looked at BTY VOR in a remote area of western Nevada. The
frequency is 114.7. Over the primary box is "122.1R." How could that
be confusing for a properly trained student pilot?

Ummm... Never underestimate a student pilot? :-)

My bad, that should have been 108.00 to 117.95. The VHF radios go from
118.00 to 135.95

I have to admit that the charting confused me at first, too. Once I had it
figured out, there's an easy way to remember it. The charts are done by the
government. Who do think they care about more, them or us? Of course it's
where *they* receive.

I guess it depends on who is "Receiving" the pilot or FSS. In anycase,
the comm radio won't reach 114.7 so the pilot will likely figure that
something is wrong.
