In this case, the geometry section consists of twelve GW elements making up the antenna. Each element is longer than the last, and to maintain accuracy, the later elements are divided into more segments. All measurements in NEC use metres, so the first element is 2 metres wide, running from -1 to 1. The GE line indicates the end of the geometry ...
The AN/PRC-150(C) Falcon II Manpack Radio, is a tactical HF-SSB/ VHF-FM manpack radio manufactured by Harris Corporation. [1] It holds an NSA certification for Type 1 encryption . [ 2 ] The PRC-150 is the manpack HF radio for the Harris Falcon II family of radios, introduced in the early 2000s.
The AN/PRC-6809 MBITR Clear is a variant of the MBITR, made available without encryption. While the PRC-148 includes US Type 1 capabilities in all versions, the PRC-6809 uses Level III Data Encryption Standard, making it available to police, firefighters, and militaries unable to obtain International Traffic in Arms Regulations (ITAR) approval.
G-code (also RS-274) is the most widely used computer numerical control (CNC) and 3D printing programming language.

The USMC ordered 60,000 radios to be used until replaced by the more complex Joint Tactical Radio System (JTRS) cluster 5 spiral 2 radio in 2013. [2] However, JTRS was cancelled in October 2011, [3] and thus the PRC-153 continues to serve. The IISR is a Motorola XTS 2500i [4] with embedded encryption module to provide secure voice communications.
The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25.It differs from its predecessor mainly in that the PRC-77's final power amplifier stage is made with a transistor, eliminating the only vacuum tube in the PRC-25, as well as the DC-DC voltage converter used to create the high plate voltage for the tube from the 15 V battery.
