It's Tuesday, but feels like Monday, and I just had to jump in on this one, since I don't feel much like working. I had one of our supervisors come in to pick up his portable, he is responsible to ensure that the train cars we use for a commuter rail system are in spec (he is the FRA inspector as well). When we asked him does he see a lot of radio problems with the car's his answer is NO. Years ago he said it was a problem, but not now. SO here is the answer to every body's question as to why narrow band and digital. Radio's manufactured in the last 2 -3 decades don't break, no more tubes, dyna motors and vibrators that wear out.
The radio manufacturers say to them selves and the FCC how do we get rid of all those perfectly good radios (the manufacturers now have the FCC in their pocket, courtesy of George W. who I regret now having voted for) and force the consumers whether they be public safety or not buy new radios and keep them in business? Make them go narrow band!! This whole exercise is nothing but a scam to keep the radio manufacturers in fat city. With narrow band in the VHF 150-170 mhz band there will be NO, NONE, ZIPPO additional channels created, UHF 450-512 went 12.5 kc spacing 15 years ago, so again no additional channels. Now that the FCC has gotten everybody in the replacement mode for radio equipment every 10 years or so, now lets now make them go ultra narrow which requires digital.
Any manufacturer that states you must go digital by 2013 should be barred from doing business with that agency for 10 years, then maybe they will change their tune. Oh you say lets go ultra narrow 10 years early so we don't have to in 2020, would you buy a computer today for a mandate in 2020? The radios of today are basically a computer. Think about that one.
When you try to compare cell phones and public safety radios you can't. Cell phones are market driven, meaning the provider wants to get the most out of his spectrum. Replacing phones every 2-3 years mean they can introduce new technologies at will and migrate the users in it. (BTW you pay for it every month in your bill) With public safety you have to use technology that's proven and is backward compatable and will work with other systems. There is no 2-3 year turnover of equipment, most departments are happy when they get new equipment every 20 years. Mainly since that's when it needs to be replaced due to age and lack of parts.
