Channel 8 Tulsa on 450.39 MHz?

[hamjosh]

Why do I hear tv channel 8 KTUL Tulsa on 450.39 MHz? Is this normal?

It's my understanding that channel 8 should be in the 180-186Mhz. I believe it's also coming through my scanner in analog, but I thought all broadcasts were now digital.

Any ideas?

Remote audio for reporters doing live shots, common around the country in the 450 range

Thanks for answering!

I can't remember the correct terminology for what they call these but this is normal. You're not actually picking up the TV channel itself but you're picking up their broadcasting it over the air to the reporters / people at the studio. It's done so the live productions can be monitored at one or both ends. The correct frequency would really be 460.3875. But if your scanner is a little bit older it will probably round it off to 450.385 or 450.390. I wish I could remember the terminology for these kind of feeds. Sometimes they'll run all day and sometimes they just have them going whenever there's some kind of live deal going on. The frequencies between 450-451 MHz are media frequencies. There's also some down in the 170 MHz range. We have one in the Dallas area that I believe is on 170.15 that's like the one you're monitoring. And of course it's all analog in most cases since the media stations have been using these frequencies for decades. I think these are called IFB frequencies? I'm sure somebody else Will know or remember the correct terminology and be able to help you out more.

It's called the IFB. Its what reporters listen to in the field to know when they are on and get their cues.

450 (repeater) and 455 mz (simplex) are the most common frequencies for this in the USA, so yes. It is very normal.

If you search these frequencies and have more than one major market TV station in your area you will find not only more IFB broadcasts but communications between ENG trucks (electronic news gathering) engineering and the station setting up microwave antennas to do remote "live shots" and coordinating and dispatching news trucks.

450 or 455 can be used as the Repeaters for these users and there is no required official offset

I can hear them on 450.210 in McAlester when conditions are good. Channel 5 uses 170.150. Lots of juicy open mic moments on that freq.
