Yesterday I priced out all the parts for the multilateration system. Nearly everything is available from Digi-Key with the exception of the LNA, an oscillator, and an SMB connector that I have to get from Mouser and an RF splitter from Mini-Circuits. One thing I like about Digi-Key’s website is that they don’t have alot of useless graphics about that just make a site slow. Simple, clean HTML. Nice.
