Please don't give your callsign but I've noticed that we have quite a few hams on here. Just curious about how many and what your interest are in the hobby. I have been a ham since 1987 and have an advanced license. I worked only CW (morse code) for many years before using voice. In the past few years I have become more interested in the digital modes. I have done slow scan tv, jt65, psk31 and my latest thing is trying to contact the International Space Station. I think I made contact yesterday using packet but I'm not positive. I got their callsign TO my callsign (UA F) so Unnumbered Acknowlegement ? Maybe one of you more familiar with packet can let me know.
