I was fortunate to receive a Glenayre 97 Series paging amp and 28v power supply from an abandoned VHF paging site.. I believe it's a 3T97A250, which there is documentation on repeater-builder about it. To my surprise, even after being abandoned for years, the amp still works. I've not done much testing with it yet at the house, but the power supply does power on & supply power and the amp comes to life, and does amplify. I fed it with a 1w signal from a Motorola mobile and the level meter on the front went to about 30-40%. Theres a label that says "Power adjusted to 150 watts" so I assume the paging company turned the power down for this particular site, so I'm not sure if 100% power is 150 watts or 250 watts.. it was used with the original exciter and other hardware, which I have but most of it is junk, and of course useless to me.
Main reason I'm posting here.. wanted to see if anyone else has used these before and if there's anything I should be looking out for. Right now I am holding it for a potential 2 meter repeater project if a tower site pans out, and plan on pairing it with a set of Motorola mobiles and a Pi running Hamvoip. I would love to use it on our current 2 meter repeater, but it takes up way too much room in the rack, and I'm not sure if these have any sort of bypass circuitry for power outage situations, and we don't really have the means to convert to a 24v backup solution with a stepdown to 12v for the repeater and other hardware on site.
