Re: Gotta love Westwood One

Back in the "bee-doop" cue tone days of Westwood One, they used to sell an all-in-one tone decoder. It would handle bee-doops, DTMF, subaudible tones, NBC cue tones, dog whistles... 8) I put one of those on an automated all-sports station, only to find it would trigger on things like ref whistles an...

Re: Audio dropouts on Yankees game broadcasts

We have an in-state satellite network that is originated at our office, with XDS receivers at the affilate ends. I have access to a management console that among other things, lets me see "receiver health" if the affiliate has the receiver connected to the Internet. Sometimes I can tell if an affili...

Re: RDS options

I didn't think there was a way to make the PS "scroll" as the RT messages do. Like Kevin says, the PS text is actually static, it just changes every few seconds. I haven't seen too many car radios (if any) that will display actual scrolling RT messages, although most of them seem to work OK with "dy...

Re: Making a case for factoring malicious use of potent energy

Other than occasional shenanigans perpetrated by the Soviets during the Cold War, I don't think I've ever heard of anyone purposely trying to hurt people with "beamforming energy". I suspect this has to do with people who supposedly are hypersensitive to RF...a tiny, tiny subset of alleged sufferers...

On the other hand, here's a Denver TV reporter who found a way to do a story on the WEA without using prohibited tones, but actual duck noises:

Re: Weird satellite problem

Just looked at our Premiere receiver and the EB/NO is full scale. If they are having problems, it is not evident here (NC). I'm wondering if different transponders can have coverage issues that affect their footprint, to the extent that some parts of CONUS have boatloads of signal and others are bar...

Re: WWV WWVH

CHU is indeed still bangin' away. I use it to set my watch when I can't get WWV. I find their "top of minute" time pip a little harder to anticipate when setting time devices, because it comes right after the time announcement. WWV is a little easier because there is a second or two after the announ...

Re: 500w translator

How about a 10-kilowatt class-A FM station? I am guessing that WQUD Erie IL got the ERP and TPO transposed on their license-to-cover application, and the Commission issued the license with an authorization for 10 kilowatts ERP.

Does that make them the first C4 station? :roll:

Was there ever a real WKRP? A callsign search only pulls up WKRP-LP in Raleigh, North Carolina, wich is a low power fm.
I have my doubts about whether that station was ever built. My office is close by the alleged location, and I can't even hear a whisper of a carrier on their frequency.

Re: Strange skills learned

At an AM site I used to take care of, the farmer next door was allowed to let his cattle graze on the tower property. He installed a "cattle gate" (a grate made of steel tubing) in the driveway underneath the vehicle gate. He assured me that the cattle would not walk across the grate because they di...

Re: Tomato Soup Incident

One of my FM sites is co-located with a DTV, with an IOT transmitter. The coolant circulating pumps have conductivity gauges attached. If those readings get too high, the transmitter won't run. That TV station was off the air for several days once, because they ran out of coolant filters. Allegedly ...
