La PORTE — Forget about the Internet, cell phones and solid-state anything at all. This group is sticking with old-fashioned vacuum tubes and antennas. Hundreds came to the Civic Auditorium in La Porte on Saturday to swap stories and hard-tofind electronic parts at the annual Cabin Fever Hamfest sponsored by the La Porte County Amateur Radio Club. Given the remarkable evolution in communications, no one would be surprised to see interest dwindling in vintage radios. Many who poked around in dusty boxes at the show Saturday recalled tinkering with electronics as kids in a way that doesn’t seem to interest younger generations as much. But club president Brian Salzer said the hobby still has life, and in the past couple of years he’s see a resurgence. Although this is one of the only electronic swap meets left in northern Indiana, those who attend are avid.
