The FCC has not put a date on any 6.25 kHz (or 6.25 kHz equivalent) mandate (except at 700 MHz), but has strongly indicated that it is their intent to get there.
Sooo, forgive me if I sound a little offbeat but I have been reading about the railroad upgrading their com's in the near future and one question comes to mind...what does it all mean?
I read about the NXDN/6.25 radio's and how com's may not be heard. Yes, I like listening in to crews calling out milepost #'s, etc. Seems like rail activity has picked up which makes for some good pictures, etc as well.
Anyway, I was wondering if someone could maybe highlight the top 5 answers that would help explain how listening to railoads in the future will be?
Thank you for your help and again forgive me if I sound a little offbeat. Not looking to argue or what is right or wrong, just some clear understanding on what it means. Thank you for the help and understanding.
Some of the conversations are downright embarassing:
I once heard a crew talking to mechanical about their lead unit went down. Mechanical, of course asks the engineer if there is any fuel in the tank. The engineer says the "dipstick" has "plenty of brown stuff sticking to it".
Some are personal:
Such as 2 trains passing each other, crew knows each other and starts talking about how one hasn't had relations in a few weeks and needs relief fast. I had been assigned to a local job out of York, was waiting to get into main track 1, our cab radio had a scan feature and yep, it was scanning.
Lets not forget the occasional ringtone noises, farting, belching and "Management" that make you feel stupid transmissions.
Sometimes the kids get ahold of their Daddy's radio(s) some keep spare portables around for various reasons and will play cops and robbers, Star Wars, among some things. There was an issue with that for about a week at Hobson Yard in Lincoln, Ne. until the radio techs tracked the transmissions down.
What locomotive mounted radio had a scan feature? Our new GE's have a "scan" button but its disabled.

"New" GE's?
New General Electric locomotives I operate/run at work. Rich knew what I was talking about

Ah, I was thinking that some division of GE was back in the Clean Cab radio business.
Who's radio are they using, or is it part of the control panel that remotely controls a separate radio unit?
Interesting.. GE and Ericsson start LMR business... GE gets out leaving Ericsson alone, Ericsson pretty much fails, Tyco/M-A Com takes over.. also ends up in hot water, Harris takes over and seems to be doing good, now GE back in with Harris.... Full circle?
Harmon is correct. I have a bunch of PDF files for this radio, including the service manual.
One of the older files (circa 1998) shows Harmon Industries on everything, including the faceplate drawing with a Harmon logo. By the early 2000's the names and logos changed to GE Global Signalling. The service manual is from 2004 and makes no mention of Harmon. FWIW, the mailing address goes to Grain Valley, MO the same location in the Harmon drawings.
Not quite,
GE is in the radio business.
GE wants out because Welch says "Be number one or a strong number 2 or get out"
Ericsson is in the phone business and in the cellular business except for US handsets.
Ericsson buys GE radio group to get into US handset market, and gets the radio business along with the deal (structured as a partnership)
Ericsson does not do well in handsets, but GE-Ericsson does OK in radio and gets some big EDACS deals.
Ericsson wants out, but contracts have to be completed, so Com-net buys the radio division.
Com-net is really not big enough to properly support the radio group, and Microwave Associates Communications (M/A-COM) buys the group.
Somewhere prior to this M/A-COM had developed OpenSky for Fedex and merges the product lines.
Then AMP buys M/A-COM, then Tyco buys AMP. (I might have the order not quite right, or even missed a step)
Then Tyco breaks into three companies, and then Harris buys Tyco Electronics.
Now we have not talked about all the Harris history which includes the creation and sale of the divisions that are now Harris Stratex Microwave (sold 2008/2009) (just now with a new name), and Harris GE train control systems (Sold 1999/2000).
Then we could do a whole nother line with the various parts and pieces of microwave radio companies that have been started, sold, or part of Motorola, GE, and/or Harris over the years.
Just when you think you have it all figured out someone buys, sells, merges or divests a critical piece.
It's hard to keep up with it all. Then you've got Wabtec doing Motorola refurbs, and JEM doing the ones with Kenwood/Icom guts.
