Stop Buzzer?

Post by Ray » Fri Jul 26, 2019 12:02 pm

I had a frequency search service ask me for our "stop buzzer" this morning. I found out they were asking for the FCC Point of Contact for shutdown. I've never heard this term used before.

Many non-US-made transmitters have/had a big red button on the front for that. I would imagine this might be the genesis of that term.

Nope.... It's a relatively new concept (last 10 years or so) which the FCC wants a real human point of contact to terminate operation in the event of significant harmful interference. It's quite common in real time frequency coordination at congested locations and major events along with ENG operations adjacent to all the new cellular and satellite uses around 2.1 and 2.5Ghz. More than once it's been needed to correct IX to adjacent licensed services.

I was thinking more in terms of the wording than the concept.

The FCC has always required notification of the control point for broadcast, even after ATS and dial-up remote controls pretty much made such a thing no longer a thing.

I have been around radio stations since high school and I have never heard this specific term.

Get into the frequency coordination business, particularly around shared RPU, cellular, satellite, and ENG operations and it's very common. It's also regularly employed by experimental operations which need to protect incumbent licensees. And it's a requirement for coordination at any major sporting event, such as all NFL games, MLB gold events, NCAA Final Four, and many others. Even major concerts... Coordinators, et al. need to reach the right people fast if there is a problem in real time.

It's just less common for the usual and normal broadcast operations of a main transmitter and nothing else.
