TortoiseMulti-Band Transmitter

Tortoise Multi-Band Transmitter is a portable, rugged, high-power stimulus 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 AB amplifiers for the cleanest signal output and VSWR protection. Tortoise can support C-band, CBRS, 3.5 GHz and most other 3G/4G/5G (non-mm wave frequencies) RF spectrum.

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 connected to any PC. Tortoise simulates CW signals complete with adjustable step sizes, channel bandwidth and user settable ID Cell, Segment and frame lengths.

What is the maximum power output from Tortoise?

Tortoise class AB amplifiers support up to 25 Watts of output power depending upon single, dual or wideband configurations.

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?

Yes. In addition, two CW frequencies may also be transmitted simultaneously all from one transmitter housing.

Can Tortoise be powered from a DC source?

No. All Tortoises are AC (110V or 220V) only.

Can Tortoise be controlled remotely?

Tortoise supports connection via USB and can be controlled remotely when connected to any Windows PC.
