: 20 Watts (stand-alone manpack); can be upgraded to 400 Watts with an external amplifier for vehicular or fixed-station use.

The operational manual for the TRC 3700 dictates a specific sequence for initialization to ensure system integrity. The process begins with the physical connection of the appropriate antenna—typically a broadband whip antenna for vehicular use or a tactical long-wire antenna for static manpack operations. The manual underscores the importance of impedance matching; failure to use the correct antenna or tuner can result in hardware damage and reduced transmission efficiency.

She flipped to Appendix C: Error Codes. E-42: PA bias voltage out of range – check J5 connector on controller PCB. The manual gave a resistance check and a simple voltage threshold. No guesswork. Just a clear diagnostic path.
