Yes, those are both good points. Also, a bad actor could straight up jam the signal. If you want to check out the signal of the competing system, it's just above or just below 15.735 MHz, using the sidebands of a shortwave broadcaster

It is a lot, but I think they want to be able to blast through difficult sunspot cycle activity. That's quite an electric bill, when you consider they're asking for up to 50 kHz bandwidth.

Yes, but they can't be used by ham radio operators.

I've seen what this is a counter proposal to on a wed-based SDR, and there were ten carriers within a 5 kHz space. The 10 carriers were switching on and off. It seemed to me like it was using a much more basic definition of digital, me

No, it would only permit commercial non-voice, non-broadcast communications on frequencies not allocated to ham radio.

My only experience with an amateur radio club: I studied to take my Technician Class exam, when I finished and passed, I found out I could take my General Class exam right then if I wished. When I took that second exam and failed, the club

In 47 CFR 73.624(b)[1], the FCC requires that broadcasters have at least one over-the-air video program signal at no direct charge to viewers. That one channel could be their home shopping subchannel, while the main ABC/CBS/NBC&#x

Historically, I've been a huge fan of OTA TV, but I just can't watch it anymore, because it's primarily an ad delivery platform. Even newscasts have home shopping segments now. The only exception is Public TV, as they are pro

Yup! The Chicago one does pretty well in the ratings. It's easier to monetize an FM radio signal than a low power TV station.

The big broadcasters would love to get rid of the OTA audience (and send them to subscription platforms). ATSC 3.0 encryption is the perfect way to do that.
101.
by RF_Enthusiast 3y ago
Those low power stations in NYC and Chicago are currently using it for a different reason. ATSC 3.0 technically allows for an analog FM side channel at the upper end of the channel's spectrum. In both of those cases, that lands right a

Keep in mind that is just AM. FM radio is still a top audio delivery platform and is not subject to the problems plaguing AM.
103.
by RF_Enthusiast 3y ago
Complaints would also have limited impact, since the stations have the right to encrypt and are breaking no laws.

OTA currently circumvents cable and satellite, in which the broadcaster gets re-transmission compensation; and circumvents their OTT delivery systems, in which they can chose to charge for access. OTA viewing, which is currently at about 20

I watched Eurovision, and now have enough excellent music to hold me over for a few months. Cha Cha Cha, y'all.

I think I know the station you're talking about. It's up in Maine-- one of their frequencies run the Overcomer Ministry and another one has dome theory flat earth programming called Worlds Last Chance. That's WBCQ. Check out

I checked another source just to be sure, but you're right! Phoenix has an empty lower-VHF dial! Prescott (Ch 6), Yuma (Ch. 2) and Tucson (Ch 4) have the lower-VHF stations in that region.

KBOO didn't purchase any spectrum, let alone double spectrum. They're a noncommercial station, which means they're not subject to application or regulatory fees. They have the rights to what every station on the FM dial has,

Channel 5 and 6 LPTV stations are being given the opportunity to upgrade from secondary spectrum user (that could be forced off their frequency) to primary spectrum user (that can't be forced off their frequency). So the option to use

Re: Turnkey Solution Bluetooth Auracast still has a chance at becoming a thing, and is a one-to-many terrestrial broadcast solution that, if implemented by manufacturers, will be available on almost any mobile device. It allows for 4 watts

The licensing for USA shortwave broadcasting is very difficult. For AM or single-sideband, you have to run a minimum transmitter output of 50,000 watts with a directional antenna. For digital/DRM, the minimum is 10,000 watts with a dir

by RF_Enthusiast 4y ago
Yeah, good point. Those people may have complained directly to the FCC, or a donor may have mentioned to KBOO that they can no longer get the station. Action may have originated on the listener level with a station as loved as KBOO.

The Portland station was broadcasting a Spanish language Christian religion format. The Eastern Oregon station was broadcasting a music format mixed with far-right talk (not to be confused with conservative talk).

by RF_Enthusiast 4y ago
Yeah, many of those translator licensees and LPFM organizers followed the rules, but not the intent of the rules. And they really pushed the limits of those rules.
115.
by RF_Enthusiast 4y ago
Yes, I think a lot of people don't know what's available (or, at least possible) on their local dial. It's hard to draw an exact parallel between public access on cable and public access on FM/AM. Public access on cable

That's funny! I just mentioned that further down in the thread at about the same time as your post. I think NZ started on FM later than many countries, so they saw the wisdom in reserving some frequencies specifically for that use. Unf

I think technology exists that could make that part of the concept work, but it would require certified transmitters that automatically check in with a database daily or hourly. There's also the issue of radiation danger. A human can n

It should be noted that the Portland pirate was interfering with a non-commercial licensed LPFM station on 90.3, and was operating on the same frequency as the digital signal of a non-commercial community broadcaster centered on 90.7. No co

Yeah, spectrum is not being used in the most efficient way. I've heard many different valid ideas on how to do it better, but, in most cases, requires a literal act of Congress.

I've purchased bandwidth in a competitive FCC auction and I'm in no way a preferred corporate buyer. If you replace "preferred corporate buyer" with "highest bidder", that would be more accurate in my experienc
