I'd like to say that this is an excellent way to re-purpose an old device. I have an old Windows Phone charging up right now to dedicate this to. I like the idea of a virtual frequency, but it seems a little confusing since it currentl

That's a fair and reasonable question to ask. Here is video of an unrelated party filming the WJLX transmission site 11 years ago: https://youtu.be/l1Srg9WEPzw?si=CVBcR3MrZ4BiaZgc The video from 11 years ago matches th

The WIXI site, 0.35 miles away, has a white building [1] [2] [3]. One-third of a mile distance in a forested area is a reasonable distance to not see the WIXI tower from the ground. I'm pretty sure the YouTube video is at the correct l

Between the danger of cutting a 1000 watt transmission line, and dismantling and hauling away a 61-meter high tower unnoticed, this seems a bit suspicious. Station data: https://fccdata.org/?facid=&call=wjlx

While a long antenna offers superior performance, a shorter one can still function, but with reduced efficiency. This trade-off becomes less critical in environments with minimal RF interference, like in the desert or in a power outage zone

In the US, AM Radio (both digital and analog) runs from 540 kHz to 1700 kHz, packing 116 channels in approximately 1 MHz (with 10 kHz spacing between stations). That's impressive efficiency for a frequency range unsuitable for much els

Swap the city perspective for the raw reality of the desert: vast and quiet, devoid of FM radio and cell phone coverage. I often traverse the vast, signal-sparse landscapes of the western US desert. These stretches are radio silence. FM? It

This is a proposal/suggestion by Kim Andrew Elliott that I think makes sense, changing the focus from an audio-focused medium to a text-focused medium. And nearly everyone has an acoustic-coupling decoder with their smartphone. This wo

We don't know what effective radiated power and antenna heights these stations [1] were using, so we can't pinpoint the areas of interference, but here are the conflicts [2] : 87.7 in Dorchester MA: Operates on same frequency as l

It's a poorly sourced paragraph. Could the author be confusing all early space television systems as being SSTV, when just some of them were?

No, I don't. It looks like the FCC is going to let the market decide on this one. The sunset date for ATSC 1.0, meaning the date that stations can choose to turn off their ATSC 1.0, is 17 July 2027 [1]. Unfortunately, I feel that conte

Yeah, it sounds like there's a considerable misunderstanding of the service YouTubeTV provides.

Does YouTubeTV carry public television stations? Aside from underwriting sponsor mentions at the beginning and end of a program, they're prohibited from mentioning sponsors [1]. [1] 47 CFR 73.621(e) https://www.ecfr.gov&#x2

This adds an uncertain future to OTA, but I don't think you can say it's implemented widely yet. Here's a list of current ATSC 3.0 channels, with an indicator for the encrypted ones: https://www.rabbitears.info&#x2

Are you saying that a transmitter with an output of 20,000 watts and a bandwidth of 50 kHz using digital modulation uses the same amount of electricity as a transmitter with 20,000 watts and a bandwidth of 1 kHz using digital modulation?

by RF_Enthusiast 3y ago
I'm talking about the bandwidth of the individual signal. A 5 kHz wide signal uses a lot less electricity than a 50 kHz wide signal.
