“From Auto Chum to Repeater Maps: How Hams Navigate the Airwaves and the Highways.”
Introduction:
Tonight’s discussion topic blends a bit of vintage travel with amateur radio:
The Rand McNally “Auto Chum”, the inaugural edition of what became the best-selling Rand McNally Road Atlas, was released on April 15, 1924. It was the first comprehensive, bound road atlas designed for motorists, featuring hand-drawn maps of the 48 states.
It wasn’t just a map - it was a companion, offering directions, suggestions, and even personality along the journey.
As hams, we’ve had our own version of that over the years:
Today, much of that has been replaced by apps and digital tools.
So tonight, let’s explore what’s changed—and what we may have gained or lost along the way.
Auto Chum as the Original Repeater Directory?
The Auto Chum told motorists:
The Move From Paper to Pixels
Today most hams use:
· Digital hotspot networks
Does digital navigation make us better operators—or just more dependent on devices?
“The Lost Art of Getting Lost” — RF Edition
Early road travelers got lost and learned from it.
Early hams also got “lost” on the bands, spinning the VFO, logging random QSOs, learning by doing.
Do we still explore? Or do we follow the same few repeaters and nets like GPS routes?
If the Grid Fails, Who Thrives?
If GPS fails, a Road Chum becomes valuable again!
If the internet fails, so does RepeaterBook, RFinder, AllStar lookups, DMR IDs, and hotspot routing.
Do you keep offline resources—paper repeater lists, local frequencies, band plans, maps?
Net Discussion Question
“If you had to take a road trip today with ONLY a Road Chum and your ham gear—no GPS, no smartphone apps—what rig would you bring, what antennas, and what frequencies would you rely on to keep connected?”
