    AM Frequency of the week: 540

    Once again....we're now working our way through channels that are now home to class A channels. Next up: 540.

    Days: At my home QTH northwest of Chicago, it's WAUK from the Milwaukee area with a fair signal. 400 watts. Low end of the dial. Pattern that's somewhat favorable to me. It all adds up to a station that gets out quite well.

    Nights: WAUK cuts off the northwest lobe which improves the signal here slightly. I still hear CBK as often as not. Usually under WAUK, sometimes mixing on an equal basis. And in winter, CBK winds up on top on some nights.

    From time to time, other stations turn up. WDAK and KNOE historically have been the most common "usual suspects". XEWA used to also be do-able as often as not, but it's been at least ten or fifteen years since I've heard that one. Does anyone (such as David) know if they're running reduced power? Or are they even still on?

    Other Location: How's this for an impressive daytime signal....

    From my own experience with the Trans-Canada Highway, CBK is audible on a good car radio, from Just inside the western border of Ontario near Falcon Lake to near Sparwood, British Columbia. Just beyond the border with Alberta. That's a distance of over 920 highway miles!

    Those two were my constants when living in Cleveland nearly 6 decades ago!

    Today, WDAK is non-directional with 36 watts at night, and KMLB (the newer calls) is 26 watts. They both appear to still be on the air, but no doubt they run syndicated programming and do nothing live and local at night.

    Since CBEF moved from 540 to 1550, there has not been a dominant station, since the US station protect the Canadian border, and CBEF was quite well protected at a 6.3 mV/m NIF contour. Last new logging on 540 is WFLF a couple of years ago in the car. Usually I get the Pittsburgh area station.

    Down here, it's only been XEWF in Tlalmanalco. The only other strong candidate is CBK in Saskatchewan. They're 50-kW ND, so I'll be looking for them.

    Just a comment that may help DXers: the Mexican licensing authority lists stations by the "location" of the station transmitter facility. The US concept of "City of License" is not one that is employed in Latin America.

    In this case, Tlalmanalco is a contiguous suburb of Mexico City, and XEWF appears in media directories as "Ciudad de México".

    Were the Mexican system to be employed, we would have KFI in Buena Park, WABC in Lodi and WKAQ in Cataño.

    So when listening for local references on a station, look for the market, not the location.

    XEPRS in Tijuana is given with a location of "Rancho del Mar" which you will never hear mentioned. Or, picking one broadcasting in Spanish, XEMO, also in Tijuana, will never mention "Rancho Vista Hermosa" nor will, in all probability, the clients with ads on the station. It will be "Tijuana" for the station and the different "Colonias" or neighborhoods for mentions of locations in ads.

    In the near north Chicago suburbs WAUK has a pretty decent signal during the day. At night the signal is still pretty good and usually on top of CBK although CBK sometimes comes in on top.

    Retro/other: Before WAUK signed on, I forgot what year, KWMT could be heard here during the day winter and summer. Long ago I have heard KNOE at night a few times, but mostly it was CBK.

    I forgot all about KWMT. I've heard them a few times during daylight hours on the SuperadioII with WAUK nulled. I've also heard them during the day under WAUK on a couple of really good car radios.

    And then there was the time a years back when for some reason KWMT was running daytime power (5KW nulled toward CBK) at night and was widely heard. As well as discussed on this board. Do any of you guys remember that? It definitely was an easy catch for me.

    In the valley of the Jolly Green Giant (Le Sueur, MN)
    Daytime-either KWMT Ft Dodge, IA (classic country) or WXYG St Cloud, MN (the Goat Album Rock). Mainly KWMT until I get on top of the hill going towards the cities then its a crap shoot
    night-usually CBK

    I don't remember that, but KWMT could be heard here during the day any time of year, except during heavy thunderstorms. Do you remember what year the 540 in the Milwaukee area went on the air?

    Day - nothing
    Night - CBK Watrous SK (CBC R1, serving Regina). XESURF Tijuana BCN (SS Religion) is often heard in the null. Very rarely, XEWA San Luis Potosi (Los 40) will make it in, about 2000 miles away at 50KW.
    At sunrise, KYAH Delta UT (News/Talk) is often heard, along with KVIP Redding CA (Religion).
    NOTE: 540 is one of those 'even' 9khz channels too. I haven't heard any TP activity here, but I know the low-power NHK1's and the CNR1s have been caught on the coast!

    WANTED
    KRXA Carmel Valley CA (Spanish Rel) - Have never heard this one, just XESURF. Doesn't help that most of the pattern goes right into the Pacific.
    KNMX Las Vegas NM (Spanish, thought I had them a few years ago with a HSFB game but it was just too weak to ID the commercial that followed.)
    773 AM's in the log, 656 FMs (250 from Western WA), That's a DXer!
    FM, AM and SW DXer of Yakima, WA! God Bless America!
    Last New FM Log: KWEN 95.5 Tulsa OK (7/23/18 Es)
    Last New AM Log: 670 KLTT CO (morning) and 1300 KOLY SD (evening), Halloween 2018
