Ok, were they off the air or just on an antenna and at a power level where you couldn't receive them. I'm a bit confused.
FWIW, yes, this is a common problem around the country on a normal day, let alone when all of the repack stations increase the demand for tower crews.
I can tell you from personal, non-repack experience, scheduling a tower crew is an exercise in frustration. There are only so many of them and a lot of things can wreck their schedules. Winds, rain, snow, low ceilings... any of that will put the brakes on a tower climb. If the delay's long enough, it impacts the next job on their schedule, starting a domino effect. Add to that flat-out emergencies, such as a tower collapse or feed-line damage that actually DOES put a station off-the-air and the schedule gets wrecked, again. Don't forget, some of the same crews also have to work FM stations into their schedule.
Someone put a bullet into our helix, forcing us to run at low power on a pathetic backup antenna. It rained on our first crew appointment, so they ditched us and went on to the next, which had complications and took longer than planned. That bumped us, again and snow wrecked another date. Finally got it fixed after a month.
Companies such as American Tower have added more crews, but even that's tough as there's not a lot of people with the skill set or the desire to spend a few days a thousand feet in the air in November in Ohio.
There's no conspiracy. It's just the nature of the beast.
