A current list of the features, as with the status this will be updated in the details.

AM features - 

- choice between 9V and 12V power source

- 5V USB port for powering phone/ipod (only works on 12V power)

- Indicator LED, intended to get brighter with tuning.  Seems to be more of a status, considering removal or changing to purely a power indicator

- Antenna out, connect an antenna for limited range broadcast (3' is the scope of the project, enough to sit at your desk, not intended to broadcast from your attic to your basement)

- Line out, feeds antenna through capicitor so you can clip a line directly to your radios antenna, in my opinion the most useful part of this as it allows a simple audio conversion from ipod to AM radio

- Fits in an Altoids tin

FM features - 

- Antenna out, range not yet determined

- Line out, same as AM

- Footprint of a 9V battery
