Re: [Discuss-gnuradio] Fw: Need Advice for SDR choice

[Andrew Rich]

I have built a little tracking device on 434.950 MHz and it uses machester 
endcoding

It TX's at 19k2

Is that something a SDR could decode ?

The other things I would like to try is ax25 packet on ISS 145.825 MHz

Satellites - mainly just interested in the specturm and see I can rx them..

How about AIS on 161 MHz ?

The standard hardware we have for what you are after is the USRP,
probably with a WBX daughterboard (50 MHz - 2.2 GHz). Look at
www.ettus.com for the range of hardware they sell.

As for the OS, you should be fine with OpenSUSE or OSX. If you're
comfortable in Linux, this is the most likely to work well for you. We
try to work in OSX as well (thanks to Michael Dickens, especially),
but most of the developers work natively in Linux.
