AM Radio Frequency Boost ???

Is it possible to boost the AM radio signal?

I remember way back when you could buy a FM signal booster, but what about the AM side?

Most of the AM stations I listen to sound pretty good, but there is one station in particular that is weak.

I have an aftermarket stereo in my Jeep, but I believe the antenna is the OEM antenna.

While aftermarket radios sometimes have weak AM tuners, that is probably not your problem. You could double check that your antenna and adapter, if it has one, is fully inserted into the antenna jack. However, I think that it's the station and you that is the problem. By the station, I mean its power output and direction. By you, I mean where you are trying to listen to it in relation to the stations transmitter site. There are plenty of stations that are actually outside of Houston that put a signal over only part of Houston. Of course, when a city is greater than 70 across from city limit to city limit you can loose just about any station somewhere. My favorite oldies station lost its HD signal just before Conroe and I lost it altogether before Huntsville. Reception in the canyons downtown is always problematic. You get the idea. . .

If you PM me the stations call letters and your location (Pearland, Sugarland, Woodlands, etc.) I'll look the station up and do some figuring for you.

Happy Trails,
Bob

I appreciate that.

However, I located the call letters. (New listener to this particular station.) KCTA out of Corpus Christi. And, here I am in Houston. I guess I'm just lucky that I'm picking up any signal at all.

Actually, I'm surprised that I can hear any of that station's broadcast.

You're about 200 miles away. That would be tough during the day. Nighttime propagation is better but they run a directional pattern at night, and Houston is on the back side in a null.

One thing about AM signal amplifiers/boosters, they boost the noise just as much as they do the signals. But the above answers are right on so far as what your issue is.

Salt marshes and flat earth help and there is not much else there to hurt southwest of Houston. AM can go a long way under those conditions and if there are no other stations on channel or the adjacent channels to interfere with the reception once it gets there. I think it must cover every Texas gas rig in the gulf - not that anyone on them has an Arbitron meter - but still, that's big chunk of the western gulf.

Happy Trails,
Bob
