CKWW
Re: CKWW
I don't know where AM580's tower is located. It's probably south of Windsor near the Detroit River. I live about two miles from the Detroit River. So, I doubt Traverse City, who's probably directional as hell, is being heard in Downriver Detroit. And, is so hard to believe that Family Life might buy time from Bell, so that they have a Detroit clearance? IHeart clears the overnight show on CKLW, CKWW clears their music shows, and their other Canadian stations clear U.S. national shows. These big syndicators need to have a Detroit clearance for national ad reasons, and their going to use the Windsor stations when they can't get a Detroit station. And, that's basically what Family Life radio is, a national programming producer.
Re: CKWW
Yes, CKLW is the official Detroit outlet for Coast to Coast. They also air US based infomercials. CKWW however, has no non musical programming other than the required public affairs shows. They had a brokered investment show from Troy until fairly recently.
I have picked up WTCM over CKWW in the western suburbs. It’s not often, but does occur. The 580 you heard might not have been Traverse City, but it’s not CKWW. I am curious as to what it may have been.
CKWW’s tower, by the way, is in Amherstburg.

Re: CKWW
I think it's a feature on another 580, possibly WTCM, that's like Focus On The Family. The WTCM minor lobe to the South is HUQE!
CKWW has a four tower in line endfire type array, oriented NNE. It has six nulls, and five minor lobes. It protects WKBN and WKZO in the Daytime, mainly. WTCM fit into the pattern when it moved to 580.

Is THAT where they got the idea for the 486-SX?

Re: CKWW
They have four towers, northeast of Amherstburg, about 4 miles east of Wyandotte.Jeff Dugan wrote: ↑Mon Jul 29, 2019 6:16 pmWhy in the world would Family Life need to have programming on CKWW when they have 4 translators in The Detroit Area, putting programming on a Canadian Station is silly when the translators run 24/7. Family Life would never buy time from anyone for programming if you have questions about this contact Family Life. I can tell you though Family Life would never buy time from any station, I have a contact in Family Life radio and here’s the name and telephone, Mike Brinks and the number is 800-733-1030.
They have several nulls in every direction except NE. Due to their deep nulls and long wavelength, carrier suppression is a real problem downriver, where an ordinary radio will sound like what single-sideband sounds like on an ordinary CB radio.
In fact, the CKWW signal in its nulls is double sideband suppressed carrier.
When I had my HF rig in my car, I could listen to them clearly using USB mode.

Their transmitter plant was perfectly positioned and aligned to serve a gigantic area of Southwest Ontario.
I was in a motel room one night in 1970 or 1971. The only station that could be heard on it was CBEF.
Re: CKWW
Once you get outside the major lobe, the Standard Pattern "ERP" based on 282 mV/m @ 1 km for 1 kW, is no higher than about 54 watts in the minor lobes, or less than about 11 watts in the nulls.
Is THAT where they got the idea for the 486-SX?

Re: CKWW
I'm thinking CBEF had it better all around. They had more power (2500d/5000n, vs. CKWW's 500u), and a better array (Taller towers of different heights).Jeff Dugan wrote: ↑Wed Jul 31, 2019 5:26 pmSo would 540 be better or worse or the same as 580 in the western portion of Detroit and beyond.
They were both beamed NE.
Re: CKWW
CBEF 540 minor lobes are as much as the equivalent of 81 watts, and the nulls as low as 11 watts. The major lobe maximum is around 36 degrees, which puts a larger arc of nulls toward the US than CKWW, which has a maximum at 26.5 degrees.
If the US and Canada could agree on a streamlining of remaining Canadian AM stations, both WRDT and CKWW and others might be able to have significant upgrades. Neither CKPR Thunder Bay nor CKAP Kapuskasing are on 580 anymore. There are no remaining AM stations in Thunder Bay. WTCM should be able to fill their null toward CKPR with their existing parallelogram. In some cases, both the US and Canada should allow full power directional FM allotments to be dropped in to replace AM stations where those stations limit the potential of AM upgrades. The fact that Canada is moving most of their AMs to directional FM allotments should be extended to allow Canadian companies to own three FMs in a market when it is done for border allotment realignment. No one listens to me anyway, so if you don't agree, don't worry. It probably won't happen anyway.

Re: CKWW
CHYR-AM 710 had a decent daytime signal into Lansing in the 70's and 80's. They switched frequencies to 730 at local sunset with reduced power. I could occasionally pick up the nighttime signal after WVIC-AM signed off, but it was barely listenable. Their format at the time was Top 40. Listened to them a lot as a teen and always thought they did a decent job with the format.
Shortwave is the ORIGINAL satellite radio.

OR, CKWW was off the air for some short bit of time, and another distant station popped into the Detroit area. I listen to CKWW on a fairly regular basis. I work in Warren and drive on southbound I-75 through Detroit, and usually can hear CKWW, quite clearly.Jeff Dugan wrote: ↑Fri Jul 26, 2019 10:22 pmFamily Life radio would never be on a Canadian station, you may have heard a Family life station from another state on 580 I've been tuned to CKWW this morning and again this evening and they're still oldies.
580+455=1035
WUFL is on 1030.
Many (used to be nearly all) AM receivers convert the signal to 455kHz and any further amplification is from that point.
Re: CKWW
I don't think the CKWW signal is strong enough near the WUFL transmitter to mix in the receiver to do that. It sounds like the 580 is getting into the WUFL transmitter and mixing and being amplified and creating the 450 kHz signal. I should go over there with an LW receiver and check 450 kHz.
This phenomenon is frequently found on FM receivers where you have two tuned to the same station. The oscillator from one radio mixes with a strong nearby signal and you can hear it all over the dial. But it requires both signals to be quite strong.

Re: CKWW
I've read about this where a neighbor in an apartment complex liked to play his stereo loud. The person that was annoyed had a stereo with a really strong oscillator and used it on his neighbor. This solved the problem.
