P25 baseband samples

[nycap]

Hello everybody! I need a sample file of baseband P25 to test my gnuradio program. Does anybody have one handy?

Thanks,
Matt

Baseband can mean so many different things. Do you want stereo IQ or FM discriminator audio?

Control channel or voice channel? FDMA or TDMA?

Hello there! FM discriminator output please. FDMA or TDMA? Both if possible, voice channel please. The decoder does FDMA and that is where I want to start although I really should familiarize myself with how all signals look on the scopes. Thanks!

Most folks messing with GNU radio want IQ sampled data.

Someone else had also asked. for a TDMA voice sample. I have one but I don't remember if it is HQPSK or what. Symbol rate is 6000. I'll create a CQPSK sample of some clear voice and post a link of both later today. I'll try to snag a C4FM sample but weekend traffic is less frequent on the IR sites.

Ok then maybe the IQ is what i need. i havnt yet been able to get the gnuradio guys to tell me exactly how to feed the file source. kind of a steep learning curve with this gnuradio.
