Local Broadcast Radio Station

http://www.fybush.com/featuredsite.html

WBBM is down the highway a little ways from my house. I modeled the 695 foot tower on my EZNEC, and it looks like a slightly higher than 1/2 wave vertical and has 7.6 dBi gain in all directions with a perfect ground model. A quarterwave vertical has just over a 5.2 dBi gain with a perfect ground.

Our local station, WNVA, is pretty close to me. I've got no idea about their tower/antenna specs but when I've built a crystal radio, it's hard for me to receive anything else. I built a Ten Tec regenerative receiver a few months ago and Radio Havanna will overload it on some bands if I'm not real careful. Does your local station have any effect on your receivers?

I have the same situation, Audie. I'm 2 miles from the antennas (phased verticals, both around 350' tall) of WRVA, 1140. But they seem to have an incredibly clean signal, as they don't bother any of my amateur gear. Pretty hard on the alarm clock radio's, though!

I'm fortunate in that I live at least air 5 miles away from the nearest AM radio station's transmitting facility so I don't have severe BCB intermod issues.

The station - WHLO; 640 - just manages 50/S9 on my R71A's S-meter on a good day. Nothing else (of either a local or DX nature) could register that kind of signal strength.

Imagine my surprise when I was tuning across 40M on Christmas night...dropped into the 6900 KHz region - and came upon a signal with pinned the R71A's S-meter with the attenuator switched in !

Was WYFR in FL on 6.915. All that with a measly 100 KW. Wonder what they're running for an antenna array...

Way back in the early 80's I worked as a contract courier for AT&T before Congress busted it up. Most of my driving was in the wee hours of the AM, and I listened to WRVA's all night show. It was for truckers, all country music and was broadcast from a truckstop near Richmond. Great signal to this end of the state. How many watts are they using at night? Are they a clear channel station?

If I try hard, I can tune to adjacent channels on my FT-840 and hear the stations there. So these local stations are pretty clean. I have three 50 kW stations within 5 miles here. My big problem is line noise. It is an intermittent friend that never goes away totally.

EDIT: WBBM- 780, WGN- 720, And WSCR 670 are all at the legal limit here in the neighborhood. I could pick those up in Kansas real easily. These are not phased, but like vertical dipoles.

Yes, 1140 is a clear channel frequency, and they advertise 50,000 watts.

I live within spitting distance of WHAV. Makes working 75M AM interesting.

I live about 40 miles each way from any AM radio station. Just the way I like it.

My friend Mike W2MLS lives a few hundred feet away from WWRL 1600 AM. Makes working pretty much any band a challenge.
