As a hobbyist in radio I like to keep track of what's going on in radio-land around me.
There is a utility company repeater near me that is basically abandoned. I used to work for the company, so when I was still there I did the narrow band and re-license. At that time, basically anyone that knew anything about the radio system had retired or got laid off. So the knowledge of the system or it's use was essentially drying up.
Fast forward 10 years and there is virtually no one there that knows anything about it. The mobiles are no longer installed, trucks have been rotated or sold, some got sold with radios still mounted in them! There is 1 control base in the main office, but I guarantee it got shut off, because when I worked there people would go where it was (a CDM1250) and turn it off because it made a noise, again lack of knowledge.
I had told an executive that we needed to keep the system up for emergency backup in case of the big disaster. At that time, we owned the site, it had backup power and I suggested at the very least we keep some portables ready to go in case we needed them. They used cell phones for everything, and like most modern "tech" people think, it's always going to work. Wrong.
That executive is now gone, the company sold, the tower site sold. But, the repeater is still on the air. And, with a lack of real understanding, they just recently renewed the license. Again, probably because they are not sure what it is, but figured they'd be safe and renew. I know how these folks operate.
So the repeater is VHF, it has an old school license - it's licensed for voice and data, 250 watts, and a 75 MIRA. I left it at 100 watts. It is on a premiere tower site, Rx at 275 feet and Tx at 200 feet. It talks, the coverage is amazing. I can hit it with my H3 from anywhere around here, and I know no one is using it, because anytime I hit it, the ID goes off, which it is set to only go off if used, and then every 15 minutes.
It's not mine, I won't use it, but a person could easily talk on it occasionally and no one would know. Anyone else have any instances like this? I find them fascinating.
