KGRX-LD

KGRX-LD is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand KGRX-LD rather than just read about it. In short: KGRX-LD (channel 19) and KGRY-LD (channel 28) are low-power television stations serving the Phoenix, Arizona, United States, metropolitan area from transmitters on South Mountain. Licensed to serve the Gila River Indian Community and owned by Gila River Telecommunications, a tribal enterprise, KGRY-LD operates in the ATSC 3.0 (Next Gen TV) format and supports the forthcoming launch of Evoca, a subscription TV servic…

Key takeaways

KGRX-LD belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect KGRX-LD to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of KGRX-LD from memory before moving on to harder problems.

Reference excerpt

KGRX-LD (channel 19) and KGRY-LD (channel 28) are low-power television stations serving the Phoenix, Arizona, United States, metropolitan area from transmitters on South Mountain. Licensed to serve the Gila River Indian Community and owned by Gila River Telecommunications, a tribal enterprise, KGRY-LD operates in the ATSC 3.0 (Next Gen TV) format and supports the forthcoming launch of Evoca, a subscription TV service, in the Phoenix area. KGRX-LD previously operated in ATSC 3.0. These stations are separate from the Gila River Broadcasting Corporation, which primarily broadcasts First Nations Experience (FNX) from transmitters on the Community itself.

History In January 2012, the Federal Communications Commission (FCC) granted the Gila River Indian Community construction permits for a series of television stations to be located on and licensed to serve the tribe. These included K19JT-D and K28MO-D. However, it was more than seven years until activity resumed on the facility; in the case of K28MO-D, the filings by Gila River had to demonstrate that KCOS-LP, a long-defunct analog station on channel 28 whose license was still on the books, was out of service. In August 2021, the transmitters came into service, operating for the first month with FNX programming in the ATSC 1.0 mode. On September 20, 2021, the stations converted to ATSC 3.0, though Evoca has still to launch in the Phoenix area. Subchannels are in place for the over-the-air distribution of three paid services. As in Boise, Idaho, customers will pay $9.50 a month for Evoca's Scout box, which is capable of receiving ATSC 1.0, ATSC 3.0, and broadband content. While in its Boise and Colorado Springs markets, Evoca carried the relevant regional sports network, it has not been able to do so in Phoenix. According to Evoca CEO Todd Achilles, this is because Sinclair Broadcast Group insisted that, if Evoca wanted to carry Bally Sports Arizona, it would have to pay retransmission consent fees for Sinclair's broadcast stations in the Boise market (CBS affiliate KBOI-TV and CW affiliate KYUU-LD). In April 2022, KGRX-LD reverted back to ATSC 1.0, citing lack of receivers in use. They returned to ATSC 1.0 with content from two different conservative-themed political networks, Newsmax2 and Real America's Voice. It was later discovered that the station was being programmed by a third party operator, and "the Community is currently considering all available options to remove this programming, which it does not endorse." As of January 2023, both networks have been removed from the channel and it carries a simulcast of sister stations KGRQ-LD and KGRF-LD, both affiliates of FNX. KGRY-LD continues to broadcast in ATSC 3.0.

Subchannel

All ATSC 3.0 stations must provide at least one channel of free-to-air television programming. As with Boise's Evoca transmitters, this obligation is fulfilled by airing BYU TV on each transmitter. Evoca offers additional programming utilizing the hybrid functionality of ATSC 3.0, similar to Hybrid Broadcast Broadband TV (HbbTV) in Europe.

Worked examples

Example 1 — a first encounter with KGRX-LD

Start with the simplest possible case. Write down what KGRX-LD claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to KGRX-LD before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about KGRX-LD ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of KGRX-LD

In research: KGRX-LD appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses KGRX-LD in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: KGRX-LD is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2021 establishments in Arizona, Gila River Indian Community, Low-power television stations in Arizona, so understanding it makes those chapters shorter.
In everyday life: Look for KGRX-LD outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
