There are actually two sites, one on the Kailua KONA side and one looking toward Hilo. They're tied together with microwave links.
Thanks for the update. I presumed that was now the case.
Actually at the hotel where we stayed during that 1964 Kona coast visit there were no hotels in the rooms (and it was a nice hotel). The only TV was in the lobby. It wouldn't be a stretch to say the picture from the Maui relay channels was actually as good, if not better in our apartment, than in that Maui hotel lobby. And that was just with rabbit ears. Of course there was no reason to watch the Maui channels, since the Honolu channels with the exact same programming came in crystal clear in our apartment.
