The railroads have until January of 2013 to replace any radios that are not narrowbanded. It doesn't mean that they have to use the new narrowband frequencies just then but they have to be ready to use them. Most radios sold to the railroads in the last few years already meet this new standard. Narrowbanding is the narrowing of the gap or spread in frequencies between channels. The link below provides a graph that explains this somewhat. http://wireless.fcc.gov/services/plmrs/images/vhfband.jpg
With railroads going to more data and train control systems they will need extra frequencies to do this.
In order to talk to Sioux City Yardmaster, we must dial in 175-175 into the Moto upon passing Homer Ne. for yarding instructions. Only narrowband I know of over the BNSF, but it has been reported BNSF Sioux City is testing P25 also.
the new Nexterna radios do... I hate those radios...
O man i even hate that word "Nexterna" they suck bad!!!!!!!!!!
Sources close to me in the RR have CSX using/testing the narrow band around certain areas.
There is alot of talk going around in Railscan Yahoo Group that the CSXT is testing out there P25 Digital system.Sources close to me in the RR have CSX using/testing the narrow band around certain areas.
