B.2.2.3 Select Squelch Override

This message is used to turn the receiver manual squelch override on and off.

Message format:

“GRM”.............Company identifier.
“C” ...................Message class.
“03”..................Message identifier.
n .......................Squelch override: (ASCII) 0 = off; 1 = on

Example message:

$PGRMC030<chksm><CR><LF>

Set the squelch to normal operation.

B.2.2.4 Remote Frequency Lists

The following two messages work together in allowing remotely connected devices to provide frequency
lists associated with and airport. The host device should first send the Remote Airport Identifier Name
message, followed by a sequence of Remote Frequency Input messages. The list type field is used to tie the
two messages together. Up to ten frequency lists are supported, each containing up to twenty entries.

B.2.2.4.1 Remote Airport Identifier Name

This message provides the airport identifier name that is used to identify to the user which airport facility
that the list of frequencies is associated with.

Message format (GTR 200):

“GRM”.............Company identifier.
“C” ...................Message class.
“04”..................Message identifier.
t ........................List type: (ASCII) “0”, “1”,…, “9”
aaaa ..................Airport Identifier of the frequency list. Note that if the airport is three characters,

then the fourth character will be filled with a space. Airport Identifiers are
restricted to using ASCII characters 0-9 and A-Z.

Example message:

$PGRMC041KOJC<chksm><CR><LF>

Airport Identifier to be associated with list #1, Airport Identifier to display is “KOJC”.

Message format (SL 40):

“MRR”.............Company identifier.
“C” ...................Message class.
“04”..................Message identifier.
t ........................List type: (ASCII) “0”, “1”,…, “9”.
aaaa ..................Airport Identifier of the frequency list. Note that if the airport is three characters,

then the fourth character will be filled with a space. Airport Identifiers are
restricted to using ASCII characters 0-9 and A-Z.

Example message:

$PMRRC042K81<space><chksm><CR><LF>

Airport Identifier to be associated with list #2, Airport Identifier to display is “K81 ”.
