     Remark(s) (U)

(U) 1. The RF rate is selectable which affects the transmission bit rate so an emissions
    designator is included for both.



(U) 2. The configuration of the radio affects various frequency hopping parameters.



(U) 2a. The number of frequencies within the hop set is user selectable from 50 to 112.



(U) 2b. The hop rate varies between 47 to 167 hops per second depending on the configuration.



(U) 2c. The hop dwell time varies from 6 to 21 milliseconds depending on the configuration.



(U) 2d. The hop pulses per dwell varies from 16 to 317 milliseconds depending on the configuration.
