Pensacola, FL MW & CC radio 2

[stormy01]

100KW. You probably could hear it during the day if you didn't have a local.

This is a stretch! There is a relatively close station on 1050, 20 miles or so away, about 3kW omnidirectional. But it is fun to speculate theoretically if this would be possible.

About 900 miles, from Monterrey, NL, Mexico to Fort Walton Beach, FL, 200 miles of which are over land with a conductivity of 5* 50kW on the low end of the MW band goes about 500 miles over water, doubling the power may add another 50 miles radius, so 550 maybe 600 miles but the entire path is not over water! But this is around 540kHz, 1050 is nearly in the middle of the MW band, so the range is even less! Perhaps with a beverage antenna or a Box Loop aimed right at Monterrey, NL with a communications receiver but not a GE SuperRadio. Possibly 'critical hours' (2 hours after sunrise/ 2 hours before sunset especially in the winter months) but unlikely at high noon.

25 kw at a low end frequency like 570 makes for an impressive groundwave signal! No wonder they sweep over the salt water like they do. It also explains why their skywave goes out a long way but does not seem to come in well anywhere.

Low MW skywave isn't as good but the groundwave blasts out there for hundreds of miles. Just look at how WNAX reaches from Rapid City to Kansas City to Minneapolis with daytime groundwave and only 5,000 watts http://www.radio-locator.com/cgi-bin/pat?call=WNAX&service=AM&status=L&hours=D. Imagine how they would do with 25 kw! Probably would be audible in Chicago's western suburbs! That's the kind of juice that RR has at 570 and it's why that frequency seems to be their most widely heard.

WNAX has the best groundwave signal I've ever heard.

Daytime, it's about a low frequency, ground conductivity, flat land, plus a scarcity of big cities. WNAX has it all. Long live WNAX!

They sure do. KWMT in Fort Dodge, Ia does pretty well also.

I'd probably give it to KFYR. The old CKY/580 was pretty impressive except to the east where problem was the null along with the Canadian Shield terrain that began about an hour or so outside of town.

Forgot about KFYR--very impressive.

OK, since we're having the "best groundwave" discussion here, I will offer up the best of all: CBK 540 Watrous, Saskatchewan. Incredible daytime groundwave signal which is basically local grade in both Edmonton and Calgary, Alberta - a good 400 miles west of it's transmitter! 50,000 watts of muscle.....

Are they ND?

 

[BRNout]

They are, day and night. One pattern, one stick. Have heard them at night from Wyoming eastward to Iowa - but it's the daytime signal that's truly impressive.

Interesting thing about skywave and frequency: when I was in Sioux Falls, South Dakota, I was able to pick up a weak signal of KNX 1070 from LA, but never actually ID'd KFI 640 (presumably in the mush of several signals - mainly the one from Iowa). The higher frequency was just a little better at bouncing that far east when neither had a conflict with a strong signal. The Tijuana-area signal at 1700 was still audible in SD as well.

But when it comes to groundwave or closer-in skywave, KFI is usually stronger than KNX.

It is true that the groundwave properties are far superior on the lower frequencies & the reverse is true with skywave.
I'd like to view CBK's groundwave pattern, but it's not on Radio Locator. Is there any other site which shows it?

Radioman, it's there but not easy to find. Here's the link: http://www.radio-locator.com/cgi-bin/info?call=CBK&service=AM

Yes, lower stations on the dial are much better for groundwave and the opposite is true at the upper end of the dial.
This is a tried-and-true example here ... check out the coverage areas of 700 WLW and 1530 WCKY, both 50K stations in Cincinnati. Even 550 WKRC, a 5,000-watt station in Cincy, has better daytime coverage than 1530.

 

[crainbebo]

Can hear CBK Watrous, SK any night here in Bothell, WA. 815 miles away. Sometimes hear KRXA Carmel, CA way under, 778 miles away. At daytime, 540 is a very faint TIS station from Burien, WA, about 20 miles away. I will post my regular AM bandscan at night soon.

Thanks BRNout--I got it.

 

[cyberdad]

CBK is audible in Winnipeg during the day....and for that matter also in northwestern, Minnesota. The latter location with some splatter from KFYR. Not exactly "listenable", but distinctly audible.

Wish I had tried when I used to go to northern Minnesota. I used to hear 580 in Winnipeg very well around Bemidji
during the day in the early 90s. They had a good oldies format then.

....Especially when they got Burton Cummings to do afternoon drive. Apparently he was....and presumably still is....an avid record collector. He was actually pretty good at the other aspects of being a jock as well...complete a good sense of humor. (He now has a park there named after him.)

I never knew he was a jock there. I presume he's from Winnipeg.

Rob, here's a novel idea, how about listening for an ID and not "I heard them say Alaska so I must have been hearing Alaska" and any other fleeting mention!

Greg
Holiday, FL

because ID's are not always possible, most is spanish, syndicated, and such and fades in and out.

i DID hear what sounded like canada on 1010 though, forgot the call letters.

i'll post a daytime up soon.

Rob,

I think you heard CFRB in Toronto.

 

[crainbebo]

Yes, it's CFRB.
