Major AM change

Huntington, West Virginia: 1200kHz:
WEMM granted move from 1470kHz.
Daytime power to increase from 5,000 watts to 22,000;
nighttime power to decrease from 72 watts to 9.

Limited to 8,000 watts critical hours.
(the two hours following sunrise and the two hours preceding sunset)

WEMM will remain non-directional, and the tower site will not change.

I would expect this move to make it much easier to log West Virginia at points west.

New AM station

Ewa Beach, Hawaii: 1320kHz:
Permit issued for new station.
5,000 watts fulltime, directional. (same pattern day & night)
21-19-16N/158-00-40W

OK, so it's not a realistic DX target for most of us (grin)...

IBOC report from Canada

See the final report of the Canadian Digital Radio Co-ordinating Group.

This committee was formed to study the technical issues involved in introducing IBOC digital radio north of the border. It included:

6 members - representing commercial broadcasters
1 member - representing the Canadian Association of Broadcasters
2 members - representing technical consultants
4 members - from the CBC
6 members - from the Canadian Research Council
5 members - from the Industry Canada and Canadian Radio-television and Telecommunications Commission

The paper is quite educational. A few interesting points:


  • It says "interference-free service for many US stations is achieved only within their 1 mV/m (60 dBµV/m) contours.", then indicates that interference would be more likely in Canada as Canadian stations are protected to their 0.5mV/m contours. Thing is, in the U.S., commercial Class B stations are also protected to their 0.5mV/m (54dBµV/m) contours. These stations are the most important stations in seven of the ten largest U.S. radio markets! - these are the stations the Canadians believe are subject to IBOC interference...


  • Note, at the end, the mention of the large amounts of heat generated by a high-level-combiner IBOC installation. 12kw of heat for one station alone in Toronto.


  • The conclusions reached by the committee:

  • The CRTC should refrain from authorizing permanent IBOC operation until Industry Canada (the technical regulators) has established appropriate technical rules.

  • Industry Canada should refrain from issuing technical rules until they complete additional studies, including field measurements, and establish mitigation measures to deal with harmful interference within the protected service areas of existing stations.
  • Canadian broadcasters should continue to monitor the availability and popularity of IBOC receivers and service in the USA to determine whether IBOC should be pushed for faster implementation in Canada.





  • The committee specifically located harmful interference from IBOC tests on CJBC-FM (90.3) Toronto within the protected contour of CBLA-FM-1 Crystal Beach (90.5).

    There's a lot more "meat" in this report. Take a look.

    DX Tests

    (as always, visit DX Tests.info for more information)

    Fort Atkinson, Wisconsin: 940kHz
    WFAW will test from midnight to 3am Central Time on November 12th. This is late Sunday night into Monday morning.

    Reports to:
    Ernie Swanson K9LO
    Chief Engineer
    WFAW Radio
    P.O. Box 94
    Fort Atkinson, WI 53538-0094

    Thanks to Ernie and Jim Pogue for arranging this test!


    The WIRL-1290 (Peoria, Illinois) test was well heard. Unfortunately I was very short on sleep that night so couldn't stay up long enough to try live, and with storms pending I didn't dare leave the gear set up for unattended recording.


    Finally, the Joint IRCA/NRC Broadcast Test Committee (the fine folks who do the work to bring you these DX Tests) have begun the "BTC Podcast". You can subscribe or download individual podcasts. The BTC Podcast will be regularly updated with new DX Test information.

    AM station deleted

    Taunton, Massachusetts: 1570kHz:
    WPEP has surrendered its license for cancellation.
    This will allow WNSH Beverly, on the same frequency, to increase daytime power from 500 watts to 30,000 and go non-directional.

    Changes granted to AM station

    University City, Missouri: 1190kHz:
    KRFT granted move from DeSoto.
    Nighttime power increased to 6.5kw (directional) from a new site at 38-26-13N/90-16-45W.
    (daytime facility remains at existing site elsewhere)

    anti-IBOC website

    Don't like HD Radio?

    Neither do Bob Savage, CEO at WYSL 1040, Rochester, NY; Watt Hairston, Chief Engineer, WSM 650, Nashville, TN; or Jerry Arnold, Director of Engineering, Midwest Communications, Terre Haute, IN. (WPRS-1440 and three FM stations)

    They've formed The Anti-IBOC Alliance. The group is aimed largely at small-group station owners, emphasizing why they should be opposed to AM HD - how it's a threat to their operations.

    The website still needs a little work, but it's well worth a visit.

    ALSO... a special request from DX Test Coordinator Jim Pogue...

    The La Salle News Tribune is writing an article about this DX Test. They want to know ASAP after the test how many people heard it and at what distance.

    Jim writes:
    "As soon as possible after the test, I’m asking everyone who hears it to send me an e-mail. In addition to telling me that you heard the test, I’d also invite your “non-technical” comments about the test as well. Most readers don’t care about weird tones and Morse code, but if you are thrilled to hear the sound of an announcer’s voice from far away north-central Illinois, that kind of comment is something average readers can understand."

    If you hear the WLPO test, please email the details to kh2ar comcast net. (insert @ and . in the appropriate places. Da*n spam criminals.)

    Major AM station changes

    Lawrenceville, Georgia: 990KHz:
    WISK files amendment to major change application.

    Amendment moves tower a few miles, reduces day power from 1,000 watts to 950, and adds 25 watts night power. New coordinates 33-57-27N/84-00-17W.

    Application is to move from 1390KHz in Americus, over 100 miles to the south.

    (to move from 1470kHz)

    Amendment specifies 8,000 watts critical hours, from sunrise to 2 hours later and from two hours before sunset to sunet. Application calls for 22,000 watts daytime, 9 watts night, non-directional.

    Wednesday, October 03, 2007

    New AM stations

    Redding, California: 600KHz:
    Modification filed to application for new station.
    800 watts daytime
    1,000 watts nighttime
    different patterns day & night
    40-30-16N/122-07-18W

    Modification reduces day power from 1,000 watts and moves transmitter site.


    Middletown, New York: 1400KHz:
    Modification filed to application for new station.
    1,000 watts fulltime
    directional daytime only
    41-28-26N/74-27-01W

    Modification moves transmitter site and adds daytime directional antenna.


    Junction City, Oregon: 960KHz:
    Modification filed to application for new station.
    50,000 watts daytime
    3,500 watts nighttime
    different patterns day & night

    Modification reduces night power from 20,000 watts.

    Monday, October 01, 2007

    New AM stations

    Santee, California: 1400KHz:
    Amendment filed to application for new station.
    500 watts fulltime, non-directional
    Daytime site: 32-53-50N/116-55-34W
    Night site: 32-51-12N/116-58-22W

    Amendment also changes the city-of-license from Lemon Grove.

    I think this would be the only two-site Class C station if authorized.

    Santee (and Lemon Grove) are San Diego suburbs.



    Kirk, Colorado: 1490KHz:
    Amendment filed to application for new station.
    250 watts fulltime, non-directional
    39-37-33N/102-35-26W

    Kirk is in the middle of nowhere (?!) a few miles south of U.S. Hwy. 36 and about 20 miles northwest of Burlington in east-central Colorado. How they expect to sell enough advertising to support a radio station out here is beyond me.



    Bon Air, Virginia: 1200KHz:
    Amendment filed to application for new station.
    50,000 watts daytime
    20,000 watts nighttime
    directional all hours, two different patterns
    37-33-24N/77-41-50W

    amendment changes transmitter site.

    Bon Air is just west of Richmond - makes a lot more sense than Kirk, Colorado!



    Waterville, Washington: 1450KHz:
    Amendment filed to application for new station.
    1,000 watts daytime
    500 watts nighttime
    non-directional
    47-38-32N/120-05-34W

    Amendment increases power and changes transmitter site.

    Waterville is about 20 miles northeast of Wenatchee in central Washington State. (and not really near any large bodies of water)
