I've been doing radio and satellite communications professionally for about
10 years now. I've just started working with SDR and I have to say...wow.
Even after 10 years as an RF tech, and university training in Computer
Science, this stuff isn't easy to just "pick up". Thanks to all
Hello all,
I need some advice. I'm trying to take UDP datagrams from one port,
transport them over an RF link to a receiver, and then send them back over
another UDP port. Sounds simple, but I'm having a difficult time with it.
