FRack
n
(
n
= 1 – 15)
Default 4/4
After transmitting a packet requiring acknowledgment, the KAM Plus waits FRACK seconds before
incrementing the retry counter and sending the packet again. If the retry count is exceeded, the
current operation is aborted. If the packet address includes relay-requests (digipeaters) the time
between retries is adjusted to FRACK × ((2 ×
m
) + 1) where
m
is the number of intermediate re-
lay stations. The FRACK timer begins when PTT is released (the packet has been sent) and is sus-
pended when data carrier from the radio is present, or when your station is transmitting.

FREequal
n
(
n
= v8.2
Default 20
Maximal number of bits in error when scanning for free signal.
FSkinv ON | OFF
Default OFF
This command controls the polarity of the FSK output on the HF port of the KAM Plus. When OFF,
MARK is open-collector and SPACE is ground. When ON, the polarity of MARK and SPACE is re-
versed.
FUlldup ON | OFF
Default OFF
When OFF, the presence of a received signal will prevent the KAM Plus from transmitting to avoid
collisions. When ON, the VHF modem is run full-duplex and the presence of a received signal will
not inhibit transmission. Full-duplex may be especially useful for split-frequency operations.
GMON v8.0
Immediate command
The GMON command places the KAM in the monitor mode, allowing you to monitor G-TOR QSOs.
To exit the GMON Mode and return to the command prompt, type [Ctrl-C][X].
GPShead
n string
(
n
= 1 – 4) (
string
up to 8 characters) v8.0
Default blank
This command determines which GPS NMEA sentences will be stored in the LT buffers.
n
deter-
mines which which buffer will be used to store the data (1 – 4) and
string
is a NMEA sentence
header.
When the string is received, the KAM Plus will store the up to 128 characters in the associated LT.
GPSInit
string
Initial text sent to terminal in GPS Mode (string up to 128 characters) v8.0
Default blank
This command establishes a string which will be sent to the attached GPS unit upon power-up.
This may be useful to configure your GPS unit to provide only the information you require. Some
GPS units may require more then one sentence; consult your GPS unit manual. To send more than
one, enter a [Ctrl-N] at the end of each sentence and the KAM Plus will send a CR/LF sequence to
the GPS unit.
