Hi, I have APRS working on Xastir on my linux machine. I see a bunch of stations when I tune to 144.390. Assuming I have a good antenna, what other modifications do I need to make to be able to recieve and transmit to the International Space Station on the 145.825? Thanks, Skyler KDØWHB -- Skyler Fennell amsatnet.info KDØWHB electricity440 at gmail.com
