What is a transmit-only frequency? I found the above in the Jeppesen Airport Chart Legend.

What would be an example of a transmit-only frequency? Is it related to Flight Service Stations? If so, how?

Where can I find an example for transmit-only frequency on a chart?
(skyvector.com) Chart Supplement for Redding Municipal Airport.

An example of transmit-only frequency would be a VOR frequency used for a remote communications outlet (RCO). From the example above, 108.4T is a transmit-only frequency using the voice channel of the VOR.

How to use: How do I contact Flight Service while in flight?
