I've never priced attenuators, but I do know that when you reach the price level of a quality notch filter, you're to the point where it's cheaper to just buy a clean used commercial radio that's purpose-built for the band you want to listen to. Especially handhelds.

That's exactly what I did for another of my hobbies, watching Great Lakes freighters. I purchased an Icom marine handheld that works great, plus it's waterproof.

The weather service has a pretty comprehensive series of maps for their transmitters.   

Relatively speaking, they use a hughamonguluss amount of power, 1000 watts usually, as compared to the average 40-50 watt power of a locomotive radio.

Their frequencies are between 162.4 and 162.55, which is just a megahertz from the railroad band at 160-161.55.  If you are close to their towers, you will get your radio front end overloaded.  Or you get plusses and minuses of two or more frequencies intermodulating in your receiver.  I agree with the previous poster about the pagers, which were located just below the RR band.  Good riddance to them!

Here's the NOAA link.

Without world class trains and internet, Indiana is failing as a sucessful competitor in the 21st Century.

The tower is located along Post Road between Brookville Road and Washington St
If in doubt, Notch it out!
