•

Enable External PA – If enabled, the radio ignores per message power values specified by

STFP and forces transmissions at a lower power level suitable for driving the external PA (around

200 mW).

[disabled, enabled; disabled]

•

Transmit Frequency – The initial frequency that the radio uses for over the air transmissions

upon booting.

[216.00625-221.9875 MHz; 220.106250]

NOTE

STFP messages specify the frequency to be used when transmitting. This parameter is ignored

once an STFP message has been received.

•

Receive Frequency – The initial that the radio uses for receiving over the air transmissions upon

booting.

[216.00625-221.9875 MHz; 220.106250]

NOTE

STFP messages specify the frequency to be used when receiving. This parameter is ignored

once an STFP message has been received.

•

Output Power – The RF Output Power from 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.

•

Duty Cycle Power Limit – Maximum output power the radio will transmit in response to a STFP

request. Radio will be able to transmit at equal to or less than the configured power value.
