Dont know if anyone knows about this, I did another search and came up with nothing in return so if I'm repeating I apologize.
1.) Go to
www.thebravest.com
2.)scroll down to the bottom and click on the image to enter the site
3.)Then once the new page loads, look at the top. You can listen to FDNY live on the web.
NOTE: It will not work with Mozilla Firefox for some reason, you will need to run Internet Explorer on this site....which sucks....i hate IE.
There are some other sites like this one -
http://www.police-scanner.info/live-police-scanners.htm
which you can search for your local area for Fire, Police, and EMS on the web - LIVE.
As always, take care and have a great day!
