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.

Re: Aligned our STL this morning. Opinions?

I had to jump back to the picture in the previous post a couple times before I realized the picture above is a split-screen of both ends of the system. :) I must be missing something...the Nicom unit at the top of the picture appears to be an FM broadcast transmitter or exciter, not a 950 MHz STL t...

Re: Factory Reset XDS PRO1P

I am guessing Scott's receiver is one that doesn't have the front panel display, which means there is no access to a daily password for logging into the embedded web page or anything else.

Re: Wanna Play "Guess What's in the Grey Box?"

Pretty sure that is a Sage Endec in the pics, which does have its own interrupt relays.

The box could be someone's homebrew version of a multi-station relay gismo. It does kinda look like there is a pair of wires between the box and the Endec relay outputs.

Re: Wanna Play "Guess What's in the Grey Box?"

Given all of the XLR connectors spraying out of that box, I would guess it is somebody's half-assed distribution amplifier (or passive splitter). Maybe to split off air chain audio to different destinations.

Re: EAS911 Unit, trying to understand relay closures

The other end of that cable should be going to either a TFT EAS-940 relay box, or else a homebrew relay apparatus, to insert EAS audio into an air chain. The DC voltage on one of your wires is probably coming from the relay coil(s) in the TFT relay box. The relay inside the EAS911 will route it to g...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

The AMC-18 replacement satellite was successfully launched by Space-X yesterday evening (10/11). The C-band portion of it will be known as "SES-11". Reportedly it will be placed into service in late November. Typically the operator will switch from the old to the new bird in the middle of the night,...

Re: ETRS Reporting Forms 2 & 3 09/27/2017

What browser were you using? There were many, many problems reported by those trying to use Internet Exploder.

Firefox and Chrome apparently work much better with ETRS. I used Chrome for filing Forms 1 & 2 (still working on 3) and have had no problems.

Re: New member - LPFM transmitter recommendations

I'm glad you were able to find a transmitter that suits your needs.

If you please, do report back after you have installed the box and lived with it for awhile.
