05....... message id
t.......... list type, input 1
f ......... frequency type:
0 = TWR, tower frequency
8 = CTF, common traffic advisory frequency
1 = GND, ground frequency
9 = DEP, departure
2 = ATS, for ATIS
: (3Ah) = FSS, flight service station

mk...... frequency:
m = desired frequency in MHz in hexadecimal, where m = desired frequency -
30h , with the desired frequency in the range of 118 to 136 MHz, or 162 MHz.
k = desired frequency in kHz where k = (desired frequency / 25 kHz) + 30h, with
the desired frequency in the range of 000 to 975 kHz in 25 kHz steps, or 0 to 39.

$PMRRC0511IT64<cr>
The above example message outputs a ground frequency type, 121.900 MHz.
Remote VOR List
The following two commands work together in allowing remotely connected devices to
provide a list of VOR frequencies to the SL30. The remote device will send a sequence of
Remote VOR Input commands (message identifier 20). When all of the VOR Input
commands have been sent, the remote device should send a Remote VOR List Trailer
command (message identifier 21) to terminate the list. The transmitted list will not be
considered complete by the SL30 until it receives the trailer message. The unit will maintain
a single remote VOR list, so each list received will replace any previous list. There may be up
to twenty entries in the remote VOR list. Any entries past twenty will be ignored.
Remote VOR Input
This input is used to input VOR frequency data used for the remote recall function.
The data consists of five characters for the VOR station identifier followed by two characters
defining the VOR frequency.
Message format:
“V” ................ Message Class. This is a VHF NAV message.
“20” ............... Message Identifier.
