This for people who have a scanner. The Freq. is 170.150. So that means still the analog age is still alive... on scanners.

Scanner Freq. for KXAS-TV (frequent dropouts)
- Thread starter eskipper411
- Start date
It comes in really great here in Wise Co. Best site to go to is:m.radioreference.comScotpfv said:I had forgotten about this until you mentioned it. I have that freq locked out on my scanner. For some odd reason at times it was silent and at other times it had the audio from KXAS. Never knew why. I'll unlock it tomm and see if anything is still there.

If you're hearing KXAS programming audio, then they're using this frequency for IFB (Interruptable foldback), mainly to let reporters in the field converse with the anchors during the newscast. Many stations use cell phones for this now.
Side note: now that the analog signals are off, crews in the field can't depend on a television set to see/hear when they're on the air, since there's a delay of up to 7 seconds between the time a signal leaves the studio and when it comes out in a digital receiver. That makes some form of IFB indispensable.

I don't know exactly how the term came about, but it's selecting certain audio sources to send to a specific location: for instance, to a reporter in the field you send them everything EXCEPT their own microphone, since the delay of their own voice is very distracting.
The "interruptable" part is because the producer in the control room (and perhaps a live truck operator) can push a button to interrupt the audio and say something directly to the reporter without it going on the air.
