[Discuss-gnuradio] powerline PHYs?

2008-10-02 Thread David Young
I am curious if/how folks are attaching SDRs to household electrical outlets for data networking experiments. Are there any kits or off-the-shelf components that adapt from 120 VAC to a form more suitable for SDR I/O? Dave -- David Young OJC Technologies [EMAIL PROTECTED

ctions are in silicon. If Marvell would publish the 88W8388 and 88W8015 documentation, it would jumpstart some open-source development. Source code is a poor replacement for proper chipset documentation. Dave -- David Young OJC Technologies [EMAIL PROTECTED] Urbana, IL * (217) 2

pps. Here is an example that uses a sound card, <http://www.araneus.fi/audsl/>. It would be neat if there were the PC audio-out equivalents of the iGo iTips power adapter plugs, with plugs that adapt audio-out to media such as AC powerline, phone wire, Cat5, and television cable. A suitable

s for reading/writing the format. The HDF format is extensible and I *think* self-describing, FSVO of self-describing. HDF might also be overkill for SDR. Just a thought. Dave -- David Young OJC Technologies [EMAIL PROTECTED] Urbana, IL * (217) 278-3933
