I’m guessing that it had 20 pre-programmed frequencies you had to figure out and enter?
Any idea what those frequencies would be for the GEXR train?
That's exactly how a modern scanner works. Older ones (from the 1970s) had fixed frequencies for each channel: you needed to buy the correct frequency crystal for each channel. Later (in 1980s maybe?) most scanners became digital and programmable.
If you only want to monitor GEXR (Square provided the link for the SWO train frequencies) you wouldn't even necessarily have to have a scanner: a (digital) shortwave radio tuned to the GEXR frequency would work well, too.
