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 ...

Re: Barix 500 Serial question

Assuming you are running the STL firmware on the Barix, this might help: https://www.barix.com/fileadmin/data/Documentation/Software_Documentation/STL/rtpstl_manual.pdf Also there is a Yahoo group for Barix users which is frequently monitored by the developers.

Re: RadioWorld Magazine

My Radio World subscription somehow got converted to "digital only" about a year ago and I stopped getting the print version.

I intended to call them and get it fixed, but I have gotten used to reading the digital version and not having to deal with disposing of another magazine.

Re: OPIF Health

The FCC has announced that it will remain open for business at least through Friday. Apparently it has funding available to operate until then, if the rest of the government can't get its panties untwisted.

Whether or not they make it a priority to fix OPIF, who knows.

Re: The high leg

Correct me if I'm wrong, but I think the OP was referring to three-phase closed delta with a high single phase leg, sometimes called a "stinger". Pretty common around here. Two of the single phase legs are the normal 120V, the high leg is around 208V. You have to be careful not to use that leg for s...

Re: Nielsen NECAT locks soundcard input at 100%

Just a WAG, but...

If you pull up the recording device properties on the laptop sound card, are there a couple of option boxes having to do with "Exclusive Mode"? Would be under the Advanced tab.

Maybe un-checking those would keep NECAT from messing with levels.

Re: adjustable Studio desk

KEZO-FM in Omaha used to have adjustable height studio furniture, for their Todd & Tyler syndicated morning show. I saw it on a studio tour some years ago. Not sure if it was custom-built or something they adapted from an existing product. Since then they have relocated studios, and I'm not sure if ...

Re: KYFR radio

Don't know anything about KYFR, but CSP is now known as Phasetek, with more or less the same people involved. You can still get some of the parts for the CSP stuff. I have a couple of phasing systems built by them.

You may want to contact Phasetek and see if they can provide documentation.
