Tortoise MultiBand Stimulus Transmitter

Tortoise™ is a lightweight, (under 20 lbs) DC powered transmitter system composed of dual independent, transmitter modules giving the user freedom to transmit on any 2 frequency bands from anywhere without expensive and bulky additonal transmitters. Each Tortoise™ is housed in a high impact ABS water resistant case. Each transmitter module has a built-in agile frequency synthesizer, dynamically controlled power amplifier and remote control of all transmitter parameters via an IR remote controller. Remote adjustments include power level, channel or frequency assignment and transmit On/Off.

Mag-Mount Antenna (perfect for drive studies)

Forecaster PC software allows Tortoise and compatible receivers such as Coyote to overlay all drive-study measurements for overall RF coverage.

Why won't my Tortoise turn on when I hook it up to a gas portable generator? Certain model generators output an impure noise spike in the AC output. This anomaly has been traced to ignition noise riding on top of the sine waveform. So while this output is fine for most devices requiring AC power, the Tortoise will not turn on because it requires pure regulated AC power. Several model Honda generators have been tested and approved for this application, and also this problem can be easily remedied by simply using an inexpensive AC surge suppressor found in any convenience or hardware store. Can Tortoise transmit from 2 modules at the same time? No, but you can mix and match 2 completely different frequencies in one unit so that you do not have to leave the field to transmit another signal.
