I was on the Amtrak Surfliner . I had made a file with just the AAR channels for the trip. But when I went to select only this file it said nothing to scan. I then went and selected a file which had all of the AAR channels it worked just fine . When I got home I downloaded the Read data files and the Surfliner file came up with the correct data. I compared it to the Railroad file and the settings were the same. One works and the other doesn't . Any suggestions ??
Did you manually create the file that did not work, entering frequencies in the systems using Sentinel? If so, were you using location on that list? If location was enabled, if you did not manually enter the location data, then the channels you entered were treated as out of range, and not enabled, unless you also manually entered the location details. If you append systems from the main database to a Favorites list, those appended systems & channels have the location details filled in. For rail, the location entered for the nationwide channels is entered as in roughly the center of the continental U.S., just west of Omaha, Nebraska, with a range of a little over 1500 miles, which covers the lower 48 states. But if you manually created your list, without location details, the location would be treated as zero degrees for both latitude & longitude, which is odd the west coast of Africa, and obviously out of range.
As
Stoli has noted, be sure that the Rail service type is enabled. For the first list you created, did you use the Rail service type, or something different?
