2. Land mobile radio system - Wikipedia

   en.wikipedia.org/wiki/Land_mobile_radio_system

   A land mobile radio system (LMRS) is a person-to-person voice communication system consisting of two-way radio transceivers (an audio transmitter and receiver in one unit) which can be stationary (base station units), mobile (installed in vehicles), or portable (handheld transceivers e.g. "walkie-talkies").

3. Project 25 - Wikipedia

   en.wikipedia.org/wiki/Project_25

   Several hand-held Project 25 radios used around the world. Project 25 (P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. [1]

   en.wikipedia.org/wiki/FM_H-10-44

   The FM H-10-44 was a switcher locomotive produced by Fairbanks-Morse from August, 1944–March, 1950. The units featured a 1,000-horsepower (750 kW), six-cylinder opposed piston prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type A trucks, with all axles powered.

5. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

6. Joint Tactical Radio System - Wikipedia

   en.wikipedia.org/wiki/Joint_Tactical_Radio_System

   The Joint Tactical Radio System (JTRS) as a Program of Record evolved from a loosely associated group of radio replacement programs to an integrated effort to network multiple weapon system platforms and forward combat units where it matters most – at the last tactical mile.

7. Television channel frequencies - Wikipedia

   FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by K200AA.; TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel E4A or channel IC, but at lower volume than wideband FM broadcast stations, because of the lower deviation.

9. Platinum-195 nuclear magnetic resonance - Wikipedia

   en.wikipedia.org/wiki/Platinum-195_nuclear...

   Among the naturally occurring isotopes of platinum, 195 Pt is the most abundant (33.8%) and the only one with non-zero spin I=1/2. [1] [2] [3] The magnetic properties of the nucleus are considered favourable; the high natural abundance coupled with a medium gyromagnetic ratio (5.768×10 7 rad T −1 s −1) result in good 195 Pt NMR signal receptivity, 19 times that of 13 C (but still only 0. ...
