There’s an oft-neglected ham band up on 900 MHz. A few Boston area groups have been making a big push to try to revive ham radio activity in our allocation up there, especially GEMOTO<\/a>. They’re a club of GE and Motorola commercial radio aficionados, so it’s no surprise that the new machine<\/a> is looking really impressive.<\/p>\n

They say they’ve got a 130 Watt repeater, with split antennas: 9dB gain on receive, 12db on transmit. I’m not normally excited by coaxial cable, but at high frequencies like 900 MHz, attenuation through cables can be magnified; they’re using 1-5\/8″ Heliax on receive, and transmitting into 3-1\/8″ solid copper “plumbing.”<\/p>\n

It’s going up on One Financial Center<\/a> in Boston. It’s a 46-story skyscraper in Boston; Wikipedia puts it at the 7th-tallest building in Boston, but, if you include the towers on top, the third-tallest. They posted some photos of the ‘radio room’ on the top, which looks more like a high-end colocation facility than a room filled with radios. The towers seem meticulously planned, with a designated receive-only zone.<\/p>\n

130 Watts into an extremely high-gain antenna on top of one of the tallest buildings in Boston? Something tells me this repeater’s going to have some range! Now I just need to pick up a 900 MHz rig.<\/p>","protected":false},"excerpt":{"rendered":"
