They are licensed licensed for it, so it sounds like this is the case. A discriminator tapped scanner or $20 RTLSDR running DSD+ should pick them up no problem provided that they are not using encryption.
If it is OK, I may also contact you by PM. I am interested in monitoring some of the new digital railroad stuff.
I have plenty of RT dongles, but am interested in using a scanner with discriminator audio. Have the PSR-600, Uniden 396/996 XTs. Have new x36HPs, know they won't work. Anyone know of someone in LA area that will tap a couple of scanners for a fee? Want to start using DSD.
As of a few weeks ago, all Metro Rail comms are now NXDN digital. Metro Red Line was the last to go, as it was a challenge since it's underground. But it has made the switch, along with the yard frequencies and the facilities maintenance channel. The employees I've talked to say they like it better than analog, they can hear the conversations much clearer. Icom radios are used, the red line cabs have remote head radios.
Awe geez... Am I actually going to have to break down and get a NXDN?
The original Goldline ops channel was really powerful. It made it all the way out to Ventura Co. Have no idea why. Might have been up at one of the mountain sites. But yes, the above/below ground situation, makes it a unique system. Glad to hear they got it right for once.
