Denver TV Stations VIA scanner

[nathancarlson]

I am able to pick up Channel 4 on 450.1625 with a 67.0 PL tone, and this is full time including commercials and everything, so I assume its not a remote up-link. I know I also have heard KOA radio and the news choppers come up once in a while on other frequencies in my seldom monitored "air" talksystem/bank. I haven't been able to find them in the database. Does anybody know what frequencies I can pick up the other channels? 7, 9, and fox? Just curious. I know that since they went to the new format, its hard to pick up TV audio the traditional way. Also, does anybody know why this is active, and what its purpose is? I live in Longmont and pick it up pretty well. It comes in handy when I want to listen to the news (since thats about all I use TV for), or since it comes up before the delay through the TV providers, I can mess with family members by correctly "guessing" the results to a game or show. .

When you hear TV audio like that it is most likely IFB Interruptible foldback - Wikipedia, the free encyclopedia

They normally use the remote pickup frequencies listed here eCFR — Code of Federal Regulations but they may also operate on commercial trunked systems or other frequencies.

You can search the FCC database for stations in the Broadcast Auxiliary service (BA) in your area.

In some areas the Society of Broadcast Engineers (SBE) has online frequency coordination databases on their local chapter web sites that list all the frequencies used by the broadcasters in that area.

Wow a Nov 2004 post, I'm beginning to feel old.

Much less traffic is being shared on these media UHF frequencies these days in favor of Nextel, Cell Phones, Blackberrys, PDA's, Pagers, iPads etc. You used to be able to hear everything.

That old post format sure looks familiar.

KCNC is using encrypted TRBO on all their 450 voice channels. IFB remains 450.1625 analog.

KMGH occasionally has news IFB on 450.5875

KUSA uses 450.3125 IFB w/buzz for both english (KUSA KTVD) and Spanish (KDEN) news broadcasts.

KOA uses 450.050 a majority of the time simulcasting their AM feed.

Thanks for the replies! I will try those out. I have wondered how they do the remote broadcasts now. I know that "mobile 4" seems like a low quality version of a video chat. It sounds like digital "garble" and looks like video chat did with a slow connection. I assume that's done via the internet with some sort of webcam system? Its always nice when I am showing off my scanner at Christmas and try to explain how its WAY more than just police scanner like my family assumed at first. I am constantly trying to improve what I have in my scanner, but its always fun finding the other capabilities. But since they changed the TV system, I am not at all familiar with how that works, or if there is much that can be done with a scanner or receiver anymore. But thats something I can research and find out about! Thanks again for pointing me in the right direction!
