Hi guys, my local TIS stations are run by Penn DOT, and they follow the pattern of Cosmik's, has to be at least 15 years of test messages, National Weather Service relays in their early days, but I've heard very few real traffic advisory messages, and lately of the ones I can hear are just giving their ID and saying 'This isa test' with an electronic voice, endlessly with no signoff. That despite the fact that we had a large construction project project on the same corridor that several of the TIS are located along!
The construction trucks might have torn up some ground on the one site closest to me, 1560, it now has hum modulated by the voice message.
