SO-50 from Cal Poly 4/24
by Jerry Buxton 23 Apr '15

23 Apr '15

There is a good pass of SO-50 right at the lunch break for CubeSat Developers' Workshop Friday April 24 starting at 19:20 UTC. Several here want to see the ham satellites in action, so I plan to be on that pass - if you work me please respond with your name and city, state rather than grid square, so they can get a feel for where you are! Thanks and 73 Jerry N0JY

Historical OSCAR 7 Recordings?
by Paul Stoetzer 23 Apr '15

23 Apr '15

This may be a bit of a long shot, but I was curious if any recordings still exist of two unique transmissions made via OSCAR 7. 1. The National Air & Space Museum dedication speech made by President Ford and rebroadcast via OSCAR 7 on July 1, 1976. 2. The codestore message congratulating Queen Elizabeth II on her Silver Jubilee, transmitted on June 5, 1977. Thanks and 73, Paul, N8HM

SO-50 dropout?
by Bill ACITO, W1PA 21 Apr '15

21 Apr '15

I took a couple month hiatus over the winter (since I was under 10 ft of snow), and now I’m back working SO-50 from work, and ramping up on the linear birds in the evening. On the last two SO-50 passes I worked (one “overhead” Saturday night, and one at 25deg an hour ago) the bird dropped out about mid-pass. I don’t remember this happening before. I use an FT530, 432-pre-amp, and Arrow antenna. With clear sky, SO-50 is pretty much full-scale. Is this antenna shielding on the bird by the bird (it has a 1/4 whip on one corner, correct)? How fast does SO-50 tumble? I am losing the 2nd half of the passes, and I don’t remember it doing that before. Bill W1PA

ISS Contacts
by John Fickes 20 Apr '15

20 Apr '15

Hello to the group With increased traffic on the ISS digipeater, what constitutes a valid contact ? Maybe this has already been discussed and there is a procedure in place? I would think that something along the lines of JT65 would work well enough to know that someone was actually on the other side of the QSO and not just a beacon. Like the exchange of call signs and grid squares, a signal report of some sorts ( of course they would all be 599 so maybe something else could be used, maybe grids would work better here instead of grids with call signs ) and then a 73 to finish it off. So something like CQ CQ KC0BMF KC0BMF de AB0CDE DMxx AB0CDE de KC0BMF EN31 KC0BMF 73 AB0CDE ABOCDE 73 KC0BMF of course like JT65 the last 73 would be optional. Using the program UISS this is pretty straight forward as you can have the messages already built in the TX APRS message except for the call sign and the callsign is added to the message by double clicking the appropriate call in the MHeard list and changing the message with the pull down window. Any thoughts would be appreciated as I'm being asked by folks what I contact this very question. 73 John KC0BMF 1:16 Minutes:Greatest commercial EVER https://www.youtube.com/watch?v=hxU1ZhINaHk
