Shock Tolerant, Solid State, Submersible Emergency Transmitter

Softronics Ltd. proposes a module-by-module design refresh of the emergency HF transmitter, based on system analysis and critical circuit/component testing done in Phase I. Specifically, each of the six module types will be replaced by a PCB/SMT equivalent module that is fit/function interchangeable. Obsolete and/or troublesome components will specifically be replaced, otherwise legacy circuitry will be retained to the maximum extent possible to preserve the reliability and operational availability of the legacy system. The exception is the obsolete analog amplifier module, which will be replaced by a high-efficiency digital amplifier. This will enable new manufacturing lots and use as spares for older transmitters. Phase II culminates in a complete system design, test, and production documentation, and the Option performs legacy environmental compliance testing.
