Parameter
R/W
Description
A) Transmit Frequency R/W
The initial frequency in the 217.44625 to 221.95625 MHz range
that the radio uses for over the air transmissions upon booting.
Note: STFP messages specify the frequency to be used when
transmitting. This parameter is ignored once an STFP message
has been received.
B) Receive Frequency
R/W
The initial frequency in the 217.44625 to 221.95625 MHz range
that the radio uses for receiving over the air transmissions upon
booting. Note: STFP messages specify the frequency to be used
when receiving. This parameter is ignored once an STFP
message has been received.
C) Output Power
R/W
The RF Output Power from 2 to 25 Watts with which the radio
transmits. Note: STFP messages specify the power to be used
when transmitting. This parameter is ignored once an STFP
message has been received.
D) Enable External PA
R/W
If enabled the radio ignores per message power values specified
by STFP and forces transmissions at the 2 Watt power level.
E) Max Message Age
R/W
The maximum age a transmit message can remain in the queue
before it is dropped. This time is measured from when the
message is received via UDP until it is about to be placed into a
packet for transmission OTA.
F) Force TX Key
R/W
“Normal” to allow
the radio to operate in data mode, “Forced” to
key the transmitter for test purposes.
TX Key Timeout
R
If TX Key is Forced, the radio will automatically De-Key after this
timeout.
