KQWB AM 1660kHz IN WEST FARGO, NORTH DAKOTA RE-LAUNCHES THEIR AM STEREO MUSIC FORMAT

Thank you to Jake Bechtold, CBT/assistant engineer, for re-launching C-QuAM stereo for their listeners. In classic "out of the box" thinking, the engineering staff placed the KQWB(AM) stereo feed from their studio onto their KBVB FM HD-3 subchannel, using the Telos Z/IP One codec from the studio to the KBVB transmitter. Sony XDR-F1HD tuner was used to receive the FM HD-3 signal directly OFF-AIR to feed the KQWB(AM) stereo transmitter!


WRDN(AM) IN DURAND, WISCONSIN WILL LAUNCH C-QuAM STEREO BROADCASTS FOR THEIR LISTENERS

Todd's First! Todd's First!

Brian Winnekins will be launching C-QuAM high fidelity stereo at WRDN(AM) in Durand, Wisconsin USA in coming weeks. Brian will be using CRL Systems AM Stereo gear. Brian received one Matrix Processor, two Spectral Energy Processors (one for each stereo channel), as well as Audio Preparation Processor, and Stereo Modulation Processor, all manufactured by CRL Systems. We are certain that WRDN listeners will rejoice in the streets!


WCOR 1490 IN LEBANON, TENNESSEE LAUNCHED PURE COUNTRY -- REAL COUNTRY MUSIC -- IN FABULOUS C-QuAM AM STEREO !!!

WCOR(AM) in Lebanon, Tennessee has returned AM stereo to their listeners. WCOR features the Real Country format, which blends the traditional sound from today's hottest new artists, with the great country music classics.

This is a recording of WCOR(AM) in the early morning hours of January 12, 2014. WCOR is a class-C AM broadcast station located in Lebanon, Tennessee operating at 1,000 watts full time, non-directional day and night, and the tower is located approximately 29 miles east of Nashville, Tennessee USA. WCOR is owned by Bay-Pointe Broadcasting company, and broadcasts various community related programs, as well as locally produced shows on a daily basis. WCOR simulcasts sister station WANT(FM) for most of its broadcast day, and carries Cumulus Media's Real Country format. Programing differs in some day parts, usually to carry local sports programing.

LISTEN TO ALMOST THIRTY MINUTES OF
WCOR COUNTRY MUSIC IN AM STEREO
:



This air check was recorded using a Tascam DR-07 digital recorder in uncompressed PCM from a Sony SRF-A100 AM Stereo "micro boombox" portable radio. A great example of how great AM Stereo sounds starts at 16 minutes, but the entire recording sounds very good. This file is uploaded in uncompressed PCM. YouTube's processing does introduce some compression. Also, the Sony radio has a touch of distortion from the C-QuAM decoding process, so the distortion heard is due to the radio, and not from WCOR. With a wideband high fidelity AM tuner, it is very easy to hear how AM stations sound- with or without AM stereo- despite the current NRSC bandwidth limitations. Try getting that with digital HD Radio on the AM MW broadcast band, especially with the widespread use of Spectral Band Replication (or SBR), which is their best guess for how the high audio frequencies should be heard!

How does WCOR transmit AM STEREO? Station engineering decided to activate the stereo encoder card that was designed and intended for use with their new modern Broadcast Electronics AM transmitter. Since WCOR has non-directional antenna pattern, simply utilizing one tower, it was very easy to launch the C-QuAM format with minimal tuning and other effort. Also, the air studio is wired for stereo, and nearly collocated with the AM transmitter, so an expensive studio-to-transmitter link was unnecessary. Try to give the station a listen one day or night from your AM stereo receiver or tuner! If you do not have an AM stereo tuner, then please contact meduci to remedy that situation!


KYET AM STEREO 1170 BROADCASTS C-QuAM STEREO WITH CLASSIC TRADITIONAL COUNTRY MUSIC FORMAT INTO MOHAVE COUNTY ARIZONA!

KYET(AM) in Kingman, Arizona signed on for the first time at 1170 kHz on October 14th, 2012. KYET is owned by broadcast veteran Joe Hart and Route 66 Broadcasting company. They have Harris DX-10 transmitter combined with the ever elusive Harris STX-1B AM stereo C-QuAM exciter. KYET is licensed by the FCC for 6kW days and one-watt nights into an omni-directional antenna pattern.

KYET's Chief Engineer says that they experienced very little difficulty in making their Harris transmitter play with the Harris stereo exciter. Rather, it was much more challenging to get the stereophonic sound from the studio to their transmitter site. "Most AM stations only need either a single narrow-band STL channel, or a dry telco circuit, or even in some cases, a POTS [plain old telephone service] line. But because we are an AM stereo music station, we need the best sounding dual-channel STL possible." KYET's transmitter is approximately 2.5 miles from the studio, and it sits on the other side of a mountain pass. So not even the tip of the 190-foot tall tower, near the junction of US93 and SR68, is visible from the roof. "Because there was no [telephone] service to our area, and the nearest telco junction box is 7,500 feet away, the local phone company wanted $42,000 to run a single residential grade phone line, with no guarantee DSL would work on it. About the only thing we could do was to partner with Datamax Wireless, who brings us 20Mbps up and down to make the I.P-based STL run. And that is actually better than the DSL connection we have at the station," says KYET's Chief Engineer. "We are currently using a pair of Barix Exstreamer 500's running MP3 compression 16-bit Stereo 48kHz, at about 256kbps, and it sounds pretty good when it hits the air. ... We are using the built-in limiter, typically running at six to 10dB of compression, and there is no other audio enhancement gear in the air chain." Since the exciter sat unused for about 12 years, the power supply required some initial repair, and the exciter was also recently modified to provide the proper NRSC pre-emphasis curve, with 10 kHz low-pass filtering.

KYET claims to be heard in Barstow, California, Wickenburg, California and loud and clear to north Las Vegas, Nevada. KYET will originate local news and talk, while maintaining the traditional country music format.


ALBUM ROCK 540 WXYG LAUNCHED AM STEREO IN SAUK RAPIDS, MINNESOTA!

WXYG STEREO AM

WXYG "THE GOAT" now broadcasts magnificent C-QuAM AM STEREO to their many listeners in St. Cloud and all of central Minnesota, as of Friday, May 3, 2013. WXYG formats album oriented rock music, playing from a large library of deep classic rock album cuts. WXYG is locally owned and operated, not a satellite feed from somewhere. WXYG's goal is to make the music they play an (un)boring listening experience. There is so much great music from the golden age of the progressive rock era. Therefore, this is not a classic rock station where they play the same 200 songs over and over again. Now presenting a new age in broadcast radio - WXYG returns the power of great music to the people. WXYG was officially launched at 5:40 A.M. on June 25, 2011 -- which was owner Herb Hoppe's 77th birthday! WXYG has Nautel ND-1 transmitter with Gates BC-1G as back-up transmitter. WXYG power is 250 watts day/night using four towers on the daytime pattern, as well as three towers on the night pattern. You can listen world-wide at>> WXYG AM STEREO.


AUSTRALIA's 2CA HAS RESUMED ANALOG STEREO TO THEIR LISTENERS!

2CA

2CA, as heard at 1053 kHz in Canberra, Australian Capital Territory, has resumed their analog C-QuAM stereo broadcasts to their listeners. With the DAB+ digital stereo launch, 2CA began exclusively airing their "Forever Classic" music format in the digital stereo format. Immediately after 2CA discontinued analog stereo, there were many unhappy listeners, that made their comments known on the station discussion boards. These regular listeners regretted the ceasure of broadcasting in C-QuAM stereo on the medium wave AM band -- they vowed to record air checks from their analog AM stereo radios if 2CA ever returned to AM stereo. Their opportunity vanished, as station management decided to discontinue analog AM stereo broadcasts to their listeners! 2CA's Internet streaming service was also discontinued. This was due to a federal court ruling that streaming of this service over the Internet was not any longer considered to be a simultaneous transmission of 2CA's medium wave radio broadcast. As a consequence, there were music licensing issues that prevent 2CA from continuing to provide this web stream. 2CA is still available to listen to ON-AIR at 1053AM.
