Matt KK4FEM just tweeted about something that happens on SO-50 when you start talking before the satellite gets into the repeat mode.
SO-50 is a CTCSS Squelch repeater. You need 67Hz tone to make it repeat your signal. The satellite must decode your signal before it will turn on the transitter. If you start talking immediately, the first letter or two of your callsign will not be heard. If you are not known, others may get your callsign wrong. Those that are full duplex have the advantage of hearing what gets transmitted. Those that are not, don't realize what is happening.
So just key up and pause a half-second before giving your callsign. You will have much better results. This does not apply to FM satellites like AO-85 which are constantly transmitting once activated.
