Bay Area Maker Faire! For once, I'm actually attached to a booth; I'll be helping the Bay-Net group show off their Software Defined Radio themed booth, so make sure to come find us if you're at all interested in SDR.
It isn't SDR related, but I will be setting up a UHF analog repeater, so if you're coming to Maker Faire and happen to have an amateur radio license, make sure to bring your radio and have 441.875MHz programmed with a +5MHz offset and 100.0Hz PL and Tone Squelch.
This is the first time I've set up a repeater at Maker Faire (and I'm not aware of it happening before). I'm really interested to see how many users an ad-hoc repeater collects at an event like Maker Faire. If you do get on it, make sure to say hi!
