TIME-OUT TIMER The TX6600PRO has a built-in time-out timer that automatically limits transmissions to a maximum of 3 minutes of continuous operation. This feature is required by the ACMA to prevent accidental blocking of the frequency should your PTT key become jammed or be otherwise pressed accidentally.
VOICE SCRAMBLER Your TX6600PRO incorporates a simple voice scrambler using band inversion technology. The scrambler is compatible with other GME radios and with most scramblers used by other manufacturers, allowing you to enjoy scrambled communications with owners of both GME and non-GME radios.
1 - 40. This feature provides additional compatibility with older 40-channel radios. Switching the filter Off increases the tolerance of the TX6600PRO receiver to older wideband 40 channel radios or to signals that might be slightly off frequency. Switching the filter On increases the selectivity of the receiver on channels 1 - 40 which can help reduce interference from strong interfering signals on adjacent channels.
1 - 40. Generally users have compensated for these differences by adjusting the volume control for each incoming signal. The TX6600PRO has a unique GME feature called Dynamic Volume Control (DVC) that automatically compensates for these variations in received audio level. When activated, this feature automatically adjusts the received audio level resulting in a constant audio output level to the speaker.
