Example message:
$PMRRV22SLE<Sp><chksum><CR><LF>
Indicates the start of a remote localizer list associated with the airport “SLE ”.
Remote Localizer Input
This input is used to input Localizer frequency data used for the remote recall function.
The data consists of three characters to identify the runway associated with the localizer,
followed by two characters defining the frequency.

“23” ............... Message Identifier.
iiii .................. Station or Runway identifier. This field will provide an identifier for the
“23” ............... Message Identifier.
iiii .................. Station or Runway identifier. This field will provide an identifier for the
localizer which can be either the actual station identifier or a string
indicating the runway associated with the localizer. The station identifier
can be up to four characters long. A runway identifier will typically be
two numbers that indicate the runway direction followed by the character
“R”, “C”, or “L” to differentiate between parallel runways (right, center,
and left). Note that if either type of identifier is less then four characters,
then the trailing characters will be filled in with spaces. Identifiers are
restricted to using ASCII characters 0-9 and A-Z.

mk.................. Frequency: m = MHz, where m = MHz frequency – 30h, with the desired
frequency ranging from 108 to 111 MHz, or 3Ch to 3Fh; k = (desired kHz
offset / 25 kHz) + 30h, where the desired frequency ranges from 000 to
950 kHz, or the even numbers from 30h to 56h. Note that the field will be
checked to ensure that it is in range and a valid localizer frequency.
Frequencies used for VORs, which can also be found in the range of
108.10 to 111.95 MHz, will not be accepted in this message type.
