Tortoise? is a portable, rugged, high-power transmitter system comprised of dual, independent modules giving the user freedom to transmit on any 2 unique frequency bands simultaneously without the need for expensive and bulky additional transmitters. Tortoise features two dynamically controlled Class A amplifiers for the cleanest signal output and VSWR protection. Tortoise features built-in thermal overheat protection circuitry with quad cooling fans to ensure against overheating during operation. Remote adjustments include power level, channel or frequency assignment and transmit On/Off via USB, RS-232 and Ethernet from anywhere. Optional LTE, UMTS, CDMA or WiMAX MODULATORS allow Tortoise? to simulate base station transmissions complete with adjustable step sizes, channel bandwidth and user settable ID Cell, Segment and frame lengths.

- CW module combos include frequencies for CDMA, Cellular, PCS, Paging, ETACS, iDEN, SMR, ISM, LMR, UMTS, GSM, LTE, WiMAX, Wi-Fi, AWS & more
